Porcine Albumin ELISA Kit (Plasma and Serum) Swine Albumin ELISA (Enzyme-Linked Immunosorbent Assay) kit employs aquantitative competitive enzyme immunoassay technique that measures swine plasma, serum in less than 3 hours. A polyclonal antibody specific for swine albumin has been pre-coated onto a 96-well microplate with removable strips. Albumin in standards and samples is competed by abiotinylated Albumin sandwiched by the immobilized antibody and streptavidin-peroxidase conjugate. All unbound material is then washed away and a peroxidase enzyme substrate is added. The color development is stopped and the intensity of the color is measured.
