The indirect ELISA method is more sensitive than the direct ELISA method as more than one labeled secondary antibody can bind the primary antibody . It is also more economical than . standardized ELISA kit or tested antibody pair Best for: analysis of complex samples, since the antigen does not need to be purified prior to measurement .
The kits include antibody-precoated plate(s) and other components to perform the assay. Each kit undergoes validation and quality testing, so laborious optimization steps (described below) are not needed. The representative data that follows was produced using a TNF alpha colorimetric ELISA kit to detect mouse TNF alpha mouse recombinant protein.Kit components & Storage An unopened kit can be stored at 2-8℃ for 1 month.
