Description & Specifications

Assay IL-4 (human interleukin-4) levels in human serum, plasma (EDTA, heparin, sodium citrate) and culture supernatant samples with our Thermo Scientific Human IL-4 ELISA Kits.

The human IL-4 ELISA kits use pre-titered, matched pairs of coating and detection antibodies to achieve sensitive and accurate measurement of interleukin-4 (IL-4), also known as B-cell stimulatory factor 1 (BSF-1, BSF1) or B-cell growth factor 1 (BCGF-1, BCGF1), in samples at 50μL per well. Also included are calibrated recombinant protein standard, TMB substrate solution and stop solution. The complete kits contain pre-coated 96-well strip plate(s) and lot-optimized reagents. All components undergo quality control testing to minimize lot-to-lot variability.
