This kit is designed as a sandwich ELISA workflow with a qPCR detection readout, described as semi-quantitative for CCL20. Practically, it can be helpful when you want a readout that supports broader dynamic tracking rather than absolute concentration reporting in every scenario. We recommend running an internal reference sample across plates and including a dilution series to confirm linearity in your own matrix, so your trend comparisons remain consistent across experiments.
The kit is positioned for use across different sample types (as stated on the product overview), but matrix effects can vary widely between serum/plasma and culture supernatants. To minimize interference, we suggest (1) performing a small pilot with spike-and-recovery in your target matrix, (2) testing 2-3 dilution factors to bring signals into a comparable window, and (3) keeping sample collection/handling consistent (freeze-thaw cycles are a common source of variability). This approach helps you separate true biology from matrix-driven shifts.
"Semi-quantitative" generally fits studies focused on relative changes (e.g., treatment vs. control, time-course trends, or pathway activation comparisons). If your manuscript requires strict absolute concentration claims across multiple matrices, you may want to validate with an orthogonal quantitative method or run a fully quantitative colorimetric kit in parallel. Many customers handle this by using the qPCR readout for screening and ranking, then confirming top findings with a quantitative assay on the final sample set.
