Sandwich ELISA analysis of Human TNF alpha Biotinylated MAb (Pierce product # M302B) was performed using components of Thermo Fisher Scientific Human TNF alpha Colorimetric ELISA Kit (Pierce product # EH3TNFA) by loading 50ul per well of Recombinant Human TNF alpha in octuplicate at 1000, 500, 250, 125, 62.5, 31.2, 15.6, and 0 pg/ml across a 5µg/ml rabbit anti-Human TNF pre-coated plate and incubated for 1 hour at room temperature. The plate was washed then incubated with 100 µl per well of Human TNF alpha Biotinylated MAb (M302B) in duplicate at 2, 1, 0.5, and 0.25 µg/ml for 1 hour at room temperature. The plate was washed and incubated with 100 µl per well of Ultra Streptavidin-HRP (Pierce product # N504) in all test wells at 1:1,500 for 30 minutes at room temperature. The plate was washed then incubated with 100ul per well of TMB substrate for 30 minutes at room temperature in the dark. The plate was then stopped with 0.16M sulfuric acid and absorbance was read on a spectrophotometer at 450-550nm.

M302B targets TNF Alpha in ELISA, and WB applications and shows reactivity with Human samples. The M303 antibody (clone 2TNF-H34A) has successfully been paired as the coating antibody in a sandwich ELISA with detection antibody M302B (biotinylated conjugate of clone 2TNG-H33).
The M302B immunogen is recombinant human TNF alpha.
M302B detects TNF Alpha which has a predicted molecular weight of approximately 26 kDa.
The M302B TNFa antibody (biotinylated conjugate of clone 2TNF-H33) has successfully been paired as the detection antibody in a sandwich ELISA with capture antibody M303 (clone 2TNF-H34A) Typical dilutions for sandwich ELISA include 1 µg/ml for coating and 0.125 - 0.25 µg/ml for detection.
Biotinylated antibody M302B (clone 2TNF-H33) and antibody M303 (clone 2TNF-H34A) have successfully been used in combination with recombinant TNFa protein STNFA in ELISA applications.
This gene encodes a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. This cytokine is mainly secreted by macrophages. It can bind to, and thus functions through its receptors TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. This cytokine is involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. This cytokine has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer. Knockout studies in mice also suggested the neuroprotective function of this cytokine.
