Human IFN gamma ELISA Kit (A334828)

Human IFN gamma ELISA Kit

Human IFN gamma ELISA Kit is a sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human IFN gamma in serum and plasma.

Sandwich (quantitative)

Human IFN gamma ELISA Kit (A334828) employs a one-step sandwich enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of human IFN gamma in serum and plasma. A 96-well microtiter plate is provided pre-coated with an antibody specific for IFN gamma. Standards and test samples are added to the wells, allowing IFN gamma to bind to the immobilized capture antibody. A prepared antibody mixture is added and incubated to form antibody–antigen complexes. After incubation, unbound material is removed by washing, and TMB substrate is added to develop colour through an HRP-catalysed reaction. The reaction is stopped with acidic stop solution, producing a yellow endpoint signal. The intensity of the colour is proportional to the amount of IFN gamma captured in each well. The concentration of IFN gamma is determined by measuring absorbance at 450 nm and interpolating from the standard curve.

This ELISA Kit contains 10X 600 µL Capture Antibodies, 10X 600 µL Detector Antibodies, 2 Lyophilized Recombinant Protein Vials, 25 mL Assay Diluent #11E5, 10X 20 mL Wash Buffer, 12 mL TMB Solution, 12 mL Stop Solution, Pre-Coated 96-Well H-Microplate (12 x 8 well strips), and 2 Plate Seals.
