Direct ELISA analysis of TNF alpha was performed by coating wells of a 96-well plate with 100ul per well of human recombinant protein TNF alpha (Product #RTNFAI) diluted in carbonate/bicarbonate buffer (Product # 28382) at a concentration of 1ug/ml overnight at 4C. Wells of the plate were washed, blocked with starting blocking buffer (Product # 37538), and incubated with 100ul per well of a mouse anti-TNF alpha monoclonal antibody (Product # M3TNFAI) at a dilution of 1:25, 1:50, 1:100, 1:200, 1:400, 1:800, 1:1600 and 1:3200 for 90 minutes at 37C. The plate was washed, then incubated with 100ul per well of a HRP-conjugated goat anti-mouse IgG secondary antibody (Product # 62-6520) at a dilution of 1:2000 for 90 minutes at 37C. Detection was performed using 1-Step Ultra TMB substrate (Product # 34028) for 5-10 minutes at room temperature in the dark. The reaction was stopped with Stop solution (Product #N600), and absorbances were read on a spectrophotometer at 450-550nm.

M3TNFAI targets TNF Alpha in ELISA, and WB applications and shows reactivity with Canine, Feline, Human, Non-human primate, and Porcine samples.
The M3TNFAI immunogen is recombinant human TNF alpha from Pichia pastoris.
M3TNFAI detects TNF Alpha which has a predicted molecular weight of approximately 26 kDa.
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.
