GRP78 is a ubiquitously expressed, 78kD glucose-regulated protein, and is commonly referred to as an immunoglobin chain binding protein (BiP). The BiP proteins are categorized as stress response proteins because they play an important role in the proper folding and assembly of nascent protein and in the scavenging of misfolded proteins in the endoplasmic reticulum lumen. Translation of BiP is directed by an internal ribosomal entry site (IRES) in the 5’ nontranslated region of the BiP mRNA. BiP IRES activity increases when cells are heat stressed (1). GRP78 is also critical for maintenance of cell homeostasis and the prevention of apoptosis (2). Luo et al. have provided findings that suggest GRP78 is essential for embryonic cell growth and pluripotent cell survival (3). In terms of diseases, GRP78 has been shown to be a reliable biomarker of hypoglycemia, to serve a neuroprotective function in neurons exposed to glutamate and oxidative stress (4), and its protein levels are reduced in the brains of Alzheimer’s patients (5). Also, the induction of the GRP78 protein that results in severe glucose and oxygen deprivation could possible lead to drug resistance to antitumor drugs (6, 7).Sample Type:TissueIntended Use:This ELISA BioAssay kit is used to quantitate GRP78 concentration in rat samples.Sensitivity:0.15ng/mlRange:0-50ng/mlSpecificity:Recognizes rat GRP78.Test Principle:This ELISA BioAssay Kit (Rat) 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 0-50ng/mL, with a sensitivity of 0.15ng/mL. The other highlights of this BioAssay kit are a quick incubation time, stable reagents, and an easy to use protocol.Kit Components:ELISA Plate, 1x96wellsStandard, 2x56.7ngStandard and Sample Diluent, 1x50mLBiotinylated Antibody Concentrate, 1x150uL10X Wash Buffer Concentrate, 1x100mLBiotinylated Antibody Diluent, 1x13mLStreptavidin Poly HRP Concentrate, 1x150uLStreptavidin Poly HRP Diluent, 1x13mLTMB Substrate, 1x13mLStop Solution, 1x13mLStorage and Stability:Store powder at 4°C liquid at -20°C. Store other components at 4°C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
