Based on how this product line is described across related listings, the colorimetric CCL26 kit is aligned with a colorimetric ELISA workflow for measuring CCL26; in this catalog, colorimetric kits are typically positioned for quantitative measurement in a standard ELISA application context. If you need strict claims for a manuscript, we recommend validating linearity in your own matrix via dilution series and running a full standard curve each time to support quantitation and reproducibility.
Serum and plasma can differ due to clotting-related release, anticoagulant effects, and protein binding. To reduce misleading shifts, use consistent collection tubes, process samples quickly, and avoid repeated freeze-thaw cycles. Run matched dilutions (at least two) for both matrices and confirm recovery with a spike test if possible. If your end goal is ranking samples rather than absolute values, keep matrix type consistent within each comparison group.
For low-abundance targets, the most effective approach is a pilot that tests larger effective input (if permitted), minimal dilution, and careful background control. Run duplicates or triplicates, and confirm that your blank and low standard points are stable. If your matrix suppresses signal, consider using a cleaner sample preparation or switching to a detection approach with higher sensitivity if available. In all cases, consistent handling and curve quality are key.
