Sandwich ELISA analysis of mouse TNF-alpha was performed using a Mouse TNF-alpha Colorimetric ELISA kit (Product # EMTNFA) by loading 50 ul per well of Mouse TNF-alpha Recombinant Protein (Product # SMTNFA) in dodecuplicate at 2450, 350, 50, and 0 pg/ml across a 3 ug/ml rat anti-mouse TNF-alpha (Product # MM350C ) pre-coated plate and incubating for 2 hours at room temperature along with 50 ul per well of rat anti-mouse TNF-alpha biotinylated antibody (Product # MM350DB). The plate was washed and incubated with 100 ul per well of Streptavidin-HRP (Product # N504) in all test wells at 1:30,000 for 30 minutes at room temperature. Detection was performed using 1-Step Ultra TMB Substrate (Product # 34028) for 30 minutes at room temperature in the dark. The plate was then stopped with 0.16M sulfuric acid. Absorbances were read on a spectrophotometer at 450-550 nm.
