Sandwich ELISA analysis of mouse IL-4 was performed using a Mouse IL-4 Colorimetric ELISA kit (Product # EMIL4) by loading 50 ul per well of Mouse IL-4 Recombinant Protein (Product # SMIL4) in dodecuplicate at 375, 75, 15 and 0 pg/ml across a 2 ug/ml rat anti-mouse IL-4 (Product # MM450C) pre-coated plate and incubating for 2 hours at 37°C. The plate was washed, then incubated with 100 ul per well of an HRP-conjugated rat anti-mouse IL-4 antibody at a concentration of 0.4 ug/ml for 1 hour at 37°C. Detection was performed using 1-Step Ultra TMB Substrate (Product # 34028) for 30 minutes at room temperature in the dark. The plate was stopped with 0.16M sulfuric acid. Absorbances were read on a spectrophotometer at 450-550 nm.
