Human WAP Four Disulfide Core Domain Protein 2 ELISA Kit

This sandwich ELISA kit from Antibodies.com enables quantitative in vitro determination of human WAP Four Disulfide Core Domain Protein 2 (HE4) in serum, plasma, saliva, tissue homogenates and other biological fluids. The assay employs a pre-coated microtiter plate and the sandwich enzyme immunoassay technique, with sequential incubation using a biotinylated anti-HE4 antibody and an HRP-avidin conjugate. Detection is performed colorimetrically by measuring the absorbance of the TMB reaction product at 450 nm in a microplate reader.

The kit has a reported assay range of 0.156-10 ng/ml and a sensitivity of 0.068 ng/ml, with a total assay time of 4h 30m, and it is reactive with human samples. Components are stored at +4°C or -20°C as instructed, and the kit should not be used past its expiration date.
