The Rat GRP78 ELISA Assay is a sandwich ELISA that can be used for the quantification of Rat GRP78 in Tissue Lysates. The ELISA utilizes an Anti-Rat GRP78 monoclonal antibody-coated plate and a Biotinylated antibody for detection which allows for an assay range of 0 to 50 ng/mL, with a sensitivity of 0.15 ng/mL. The other highlights of this kit are a quick incubation time, stable reagents, and an easy to use protocol.
