Enzyme Linked Immunosorbent Assay Rabbit Tumor Necrosis Factor α Collect Sample – serum or blood plasma Storage: 2 - 8 °C Package size: 96 determinations PRINCIPLE OF THE METHOD： The TNF-α kit is a solid phase phase sandwich enzyme linked immuno sorbent assay(ELISA). Samples , including standards of known TNF-α concentrations and unknowns are pipetted into these wells. During the first incubation, the TNF-α antigen and a biotinylated monoclonal antibody specific for TNF-α are simultaneously incubated.Afterwashing, the enzyme(streptavidin-peroxydase)is added. After incubation and washing to remove all the unbound enzyme, a substrate solution which is acting on the bound enzyme is added to induce a coloured reaction product. The intensity of this coloured product is directly proportional to the concentration of TNF-α present in the samples.
