Product Brief

  • Introduction

    Boster's GRP78 ELISA 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.

    Properties

    Sensitivity0.15 ng/ml
    *Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive.
    Assay Range0 - 50 ng/ml
    *This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range.
    Sample TypeTissue

    *The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine? ELISA kit should detect it. 
    **For protocol and tips regarding preparing your sample of interest, please check our ELISA sample preparation guide.
    StorageStore at 4°C.

    Gene NameHspa5
    Protein NameEndoplasmic reticulum chaperone BiP
    Protein FunctionEndoplasmic reticulum chaperone that plays a key role in protein folding and quality control in the endoplasmic reticulum lumen (By similarity). Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10/ERdj5, probably to facilitate the release of DNAJC10/ERdj5 from its substrate (By similarity). Acts as a key repressor of the ERN1/IRE1-mediated unfolded protein response (UPR). In the unstressed endoplasmic reticulum, recruited by DNAJB9/ERdj4 to the luminal region of ERN1/IRE1, leading to disrupt the dimerization of ERN1/IRE1, thereby inactivating ERN1/IRE1. Accumulation of misfolded protein in the endoplasmic reticulum causes release of HSPA5/BiP from ERN1/IRE1, allowing homodimerization and subsequent activation of ERN1/IRE1 (By similarity).
    Subcellular LocalizationEndoplasmic reticulum lumen.
    Uniprot IDP06761
    Alternative NamesEndoplasmic reticulum chaperone BiP

    Background for Endoplasmic reticulum chaperone BiP

    GRP78 is a ubiquitously expressed, 78-kDa 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. GRP78 is also critical for maintenance of cell homeostasis and the prevention of apoptosis. Luo et al. have provided findings that suggest GRP78 is essential for embryonic cell growth and pluripotent cell survival. 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, and its protein levels are reduced in the brains of Alzheimer’s patients. Also, the induction of the GRP78 protein that results in severe glucose and oxygen deprivation could possible lead to drug resistance to anti?tumor drugs.

Instructions

Intra/Inter Assay Precision

Intra-Assay Precision: Three samples of known concentration were assayed thirty times on one plate. The intra-assay coefficient of variation of the Nitrotyrosine ELISA has been determined to be <10%.
Inter-Assay Precision: Three samples of known concentration were assayed thirty times in three individual assays. The inter-assay coefficient of variation of the Nitrotyrosine ELISA has been determined to be <15%.
