产品概述

The rat IL-4 ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for detection of IL-4 in rat plasma, serum, and cell culture samples.This assay employs a quantitative sandwich enzyme immunoassay technique that measures rat IL-4 in approximately 3.5 hours. A polyclonal antibody specific form rat IL-4 has been pre-coated onto a 96-well microplate with removable strips. IL-4 in standards and samples is sandwiched by the immobilized antibody and a biotinylated polyclonal antibody specific for rat IL-4, which is recognized by a streptavidin-peroxidase (SP) conjugate. All unbound material is washed away and a peroxidase enzyme substrate is added. The color development is stopped and the intensity of the color is measured.
