Q: Why are there two different Human Chemokine 11-Plex panels?

The two panels cover complementary chemokine families. Panel 1 covers the CCR1/CCR2/CCR3/CCR4/CCR5/CXCR1/CXCR3 axes — the most commonly studied chemokine receptors in inflammation and oncology. Panel 2 covers the CCR6/CCR7/CCR9/CCR10/CXCR4/CXCR5/CX3CR1 axes plus MIF — extending coverage to dendritic cell trafficking (CCR6/CCR7), mucosal homing (CCR9/CCR10), hematopoiesis (CXCR4/SDF-1α), and the unique CX3CR1/Fractalkine axis. The 13-Plex combines coverage from both into a single larger panel. Choose Panel 1 for core chemokine profiling, Panel 2 for extended trafficking coverage, or the 13-Plex for the most comprehensive single-well chemokine measurement.

Quantify chemokine-mediated immune cell trafficking, migration, and chemotaxis using MSD multiplex panels spanning the CXCL and CCL chemokine families — from focused 6-plex mouse panels to comprehensive 13-plex human chemokine configurations, across human, mouse, and NHP.

Chemokines are the molecular navigation system of the immune system — a network of approximately 50 structurally related chemoattractant cytokines that direct leukocyte migration through concentration gradients. Unlike classical cytokines that primarily regulate immune cell activation and polarization, chemokines govern where immune cells go: CXCL chemokines (IP-10/CXCL10, IL-8/CXCL8) direct neutrophil and Th1 cell trafficking; CCL chemokines (MCP-1/CCL2, MIP-1α/CCL3, RANTES/CCL5) recruit monocytes, macrophages, and T cells. Dysregulated chemokine networks underlie the immune infiltration of tumors, the synovial inflammation of rheumatoid arthritis, the demyelinating lesions of multiple sclerosis, and the atherosclerotic plaque formation of cardiovascular disease. Dedicated chemokine panels — recognized as a distinct service category by leading CROs offering independent Chemokine Panel I product lines — capture this trafficking dimension that general cytokine panels do not adequately address.

Why Chemokines Deserve Their Own Panel

General cytokine panels answer "is there inflammation?" Chemokine panels answer "which immune cells are being recruited, and to where?" The distinction matters: a researcher studying tumor immune infiltration needs to know whether MCP-1 (monocyte recruitment) or IP-10 (Th1/Tc cell recruitment) is driving the infiltrate — information lost when chemokines are buried among 30+ general cytokines in a broad panel. Chemokines also present unique analytical challenges: they share high structural homology within subfamilies (MIP-1α vs. MIP-1β; MCP-1 vs. MCP-2 vs. MCP-4), operate at low pg/mL concentrations, and their biological interpretation requires knowledge of receptor-ligand pairing. For example, CCR5 binds MIP-1α, MIP-1β, and RANTES simultaneously — measuring all three ligands in a single well provides the integrated CCR5 signal that single-analyte assays cannot reconstruct. Dedicated chemokine panels address these challenges: structurally related chemokines occupy separate electrode spots with no cross-talk; ECL sensitivity captures low-abundance chemokines in the pg/mL range; and panel composition is organized by receptor specificity rather than arbitrary plex count.

 What Dedicated Chemokine Panels Provide
Receptor-axis-resolved trafficking data: IP-10/CXCL10, I-TAC/CXCL11, and MIG/CXCL9 are the three CXCR3 ligands directing Th1 and CD8+ T-cell trafficking — measuring all three simultaneously provides the integrated CXCR3 chemotactic signal. The Human Chemokine 13-Plex covers the major chemotactic axes: CCR1/CCR5 (MIP-1α/β, RANTES), CCR2 (MCP-1/2/3/4), CCR3 (Eotaxin family), CCR4 (MDC, TARC), and CXCR1/CXCR3 (IL-8, IP-10).
Chemokine-specific analytical performance: MSD's spatially separated electrode spots eliminate cross-talk between structurally related chemokines. MIP-1α and MIP-1β share 70% sequence homology yet occupy separate spots with independent signal readout. The V-PLEX Chemokine Panel lot-to-lot bridging ensures that chemokine measurements remain analytically comparable across multi-year studies.
Species-matched translational chemokine panels: Mouse chemokine panels include species-specific KC/GRO (functional homolog of human IL-8) and MIP-2 — chemokines absent from human panels but essential for murine inflammatory models. NHP panels cover the chemokines most relevant to non-human primate infection and vaccine models, enabling preclinical-to-clinical chemokine data comparison on the same analytical platform.
Complementary to cytokine panels, not competing: a cytokine panel + a chemokine panel from the same 50 µL sample provides comprehensive immune profiling — which cells are activated (cytokines) and where they are being recruited (chemokines). This is the analytical combination used in leading CRO chemokine service offerings.

Chemokine Receptor-Ligand Biology — The Six Major Axes

CCR1/CCR5 — Myeloid & Th1 Recruitment

Ligands: MIP-1α/CCL3, MIP-1β/CCL4, RANTES/CCL5, MCP-3/CCL7. Biology: CCR5 is the major HIV co-receptor and a therapeutic target (maraviroc). CCR1/CCR5 ligands recruit monocytes, NK cells, and Th1 cells. CCR5Δ32 mutation confers HIV resistance — a naturally occurring human gene knockout validating this axis as a therapeutic target.

CCR2 — Monocyte Recruitment

Ligands: MCP-1/CCL2 (primary), MCP-2/CCL8, MCP-3/CCL7, MCP-4/CCL13. Biology: the dominant monocyte recruitment axis. MCP-1/CCR2 drives macrophage infiltration in atherosclerosis, tumor microenvironments, and adipose tissue inflammation. The most therapeutically targeted chemokine axis — CCR2 antagonists in clinical development for NASH, oncology, and fibrosis. The 13-Plex measures all four MCP family members.

CCR3 — Eosinophil & Basophil Recruitment

Ligands: Eotaxin/CCL11, Eotaxin-2/CCL24, Eotaxin-3/CCL26. Biology: the eosinophil recruitment receptor. Eotaxins are central to allergic inflammation, asthma, eosinophilic esophagitis, and atopic dermatitis. Eotaxin-3 is the most specific and potent CCR3 ligand. The 13-Plex includes all three eotaxin family members for comprehensive Type 2 inflammation assessment.

CCR4 — Th2 & Treg Recruitment

Ligands: MDC/CCL22, TARC/CCL17. Biology: Th2 and Treg cell recruitment. MDC and TARC are elevated in atopic dermatitis, Hodgkin lymphoma, and mycosis fungoides. CCR4 is a validated therapeutic target — mogamulizumab (anti-CCR4) is approved for cutaneous T-cell lymphoma. Both ligands are included in the 11-Plex Panel 1 and 13-Plex.

CCR6 — Th17 Cell Homing

Ligand: MIP-3α/CCL20. Biology: the sole CCR6 ligand — recruits Th17 cells and dendritic cells to mucosal surfaces and inflammatory sites. Central to the IL-23/IL-17/CCL20 feedback loop driving psoriasis. CCR6+ Th17 cells are the dominant pathogenic population in MS, IBD, and psoriatic arthritis. Available in the 11-Plex Panel 2.

CXCR3 — Th1 & CD8 T-Cell Trafficking

Ligands: IP-10/CXCL10, I-TAC/CXCL11, MIG/CXCL9. Biology: the dominant Th1 and cytotoxic T-cell recruitment axis. IP-10 is one of the most consistently elevated chemokines across infection, autoimmunity, and allograft rejection. I-TAC is the highest-affinity CXCR3 ligand. Both are available in our chemokine panels — IP-10 in all human panels, I-TAC in the 11-Plex Panel 2. Measuring all three CXCR3 ligands provides the integrated chemotactic signal for this axis.

Electrochemiluminescence for Chemokine Detection

Advantages for Chemokine Measurement

Spatial separation eliminates cross-talk: structurally related chemokines (MIP-1α vs. MIP-1β, 70% sequence homology; MCP-1 vs. MCP-4) occupy separate electrode spots with electrically addressed readout — no spectral overlap, no compensation. Each chemokine produces an independent, cross-talk-free signal regardless of structural similarity.
Low pg/mL sensitivity: chemokines operate at concentrations often 10–100× lower than classical cytokines. ECL's background-free detection — where SULFO-TAG labels emit only upon electrical stimulation at the electrode surface — provides the sensitivity needed for reliable chemokine quantification in complex matrices.
Wide dynamic range per spot: chemokine concentrations can span 3–4 orders of magnitude across different biological contexts (e.g., IP-10 from ~50 pg/mL at baseline to >5,000 pg/mL during acute inflammation). ECL's 4–5 log dynamic range accommodates this without dilution.
V-PLEX lot bridging: documented chemokine reagent lot-to-lot consistency for multi-year longitudinal studies — critical given that chemokine panel configurations may span the entire duration of a clinical development program.

Why Choose Electrochemiluminescence for Chemokine Detection

Dedicated chemokine panels — not a cytokine afterthought: chemokine-specific multiplex configurations designed around receptor biology rather than simply extracting chemokines from general cytokine panels. Leading CROs recognize chemokine profiling as a distinct service category with dedicated product offerings
Zero cross-talk between structural homologs: MIP-1α and MIP-1β share 70% sequence identity — on bead-based platforms, their overlapping emission spectra introduce compensation error. MSD's spatially separated electrodes eliminate this problem entirely
Receptor-axis-resolved data interpretation: chemokine concentrations reported by receptor family (CCR1–CCR6, CXCR1–CXCR6, CX3CR1) rather than as an undifferentiated list — enabling biologically coherent trafficking analysis
25 µL for 13 chemokines: the same sample volume as a single ELISA well. A chemokine panel + cytokine panel from a single 50 µL plasma aliquot provides comprehensive immune profiling
Species-matched translational panels: human, mouse, and NHP chemokine panels on the same platform — enabling preclinical-to-clinical chemokine data comparison without cross-platform variability

Frequently Asked Questions

How do chemokine panels differ from general cytokine panels?

Cytokine panels measure immune activation and polarization (Th1/Th2/Th17). Chemokine panels measure immune cell trafficking — where immune cells are being recruited. While there is some overlap (many broad cytokine panels include a few chemokines), dedicated chemokine panels provide: deeper coverage of structurally related chemokines without cross-reactivity; organization by receptor family (CCR1–CCR6, CXCR1–CXCR6) for biologically coherent interpretation; and sensitivity optimized for the low pg/mL concentrations at which chemokines operate. For research focused on cell migration, tumor immune infiltration, or chemokine receptor pharmacology, a dedicated chemokine panel provides more actionable data than a general cytokine panel.

Why are there two different Human Chemokine 11-Plex panels — which should I choose?

The two panels cover complementary chemokine families. Panel 1 covers the CCR1/CCR2/CCR3/CCR4/CCR5/CXCR1/CXCR3 axes — the most commonly studied chemokine receptors in inflammation and oncology. This is the panel most frequently used as a standalone chemokine assay. Panel 2 covers the CCR6/CCR7/CCR9/CCR10/CXCR4/CXCR5/CX3CR1 axes plus MIF — extending coverage to dendritic cell trafficking (CCR6/CCR7), mucosal homing (CCR9/CCR10), hematopoiesis (CXCR4/SDF-1α), and the unique CX3CR1/Fractalkine axis. 13-Plex combines the highest-demand analytes from both into the most comprehensive single-well chemokine measurement. Choose Panel 1 for core inflammatory chemokine profiling, Panel 2 for extended trafficking coverage, or the 13-Plex for maximum receptor-axis coverage in one well.

Can chemokine and cytokine panels be run on the same sample?

Yes. Both require 25 µL per panel on the same MSD platform. A single plasma aliquot can support a chemokine panel (11–13 analytes) plus a cytokine panel (10–30 analytes) — 50 µL total for comprehensive immune trafficking + immune activation profiling. This is particularly valuable for studies where chemokine-directed cell migration and cytokine-mediated immune polarization are both relevant to the research question, such as tumor microenvironment characterization or autoimmune disease immunophenotyping.

What sample preparation is recommended for chemokine measurement?

EDTA plasma is preferred — the clotting process in serum collection releases platelet-derived chemokines and cytokines that can artifactually elevate certain measurements. Process within 1 hour of collection at 4°C, centrifuge at 1,500×g for 10 minutes at 4°C, aliquot into polypropylene cryovials, and freeze at −80°C. Chemokines are susceptible to freeze-thaw degradation; single-use aliquots are strongly recommended. Consistent matrix use within a study is essential — do not mix serum and plasma. For cell culture supernatant, centrifuge to remove cells and debris before freezing.
