Researchers have indicated that they want access to novel target antibodies quickly to aid in their research. IMGENEX is pleased to be able to offer researchers access to cutting-edge products that are still in the process of characterization/validation. IMGENEX’s ‘IMX’ antibody line is shown by ELISA to bind to the peptide used as immunogen. Investigators should empirically determine the suitability of the antibody, including optimal dilutions, for other applications of interest.

We cannot guarantee that the yet-to-be-fully validated antibody will work in any application other than in an ELISA against the peptide used as immunogen and therefore cannot offer a refund if the antibody does not work in your application.
The antibody is offered at a lower price compared to a more highly validated antibody.
We are not able to provide the immunogen for the antibodies, but do provide the amino acid sequence.

These antibodies are not fully validated and we appreciate your feedback. Customer feedback is used to help generate testing methodologies which can lead to further product validation or withdrawal.
  Principal Names: BiP; GRP78; Glucose-regulatory protein; HSPA5; Immunoglobulin heavy chain-binding protein; Endoplasmic reticulum luminal Ca2+ binding protein grp78; MIF2; Heat-shock 70KDa protein 5; Official Gene Symbol: HSPA5 Gene ID: 3309(Human) Gene Map Locus: 9q33-34.1(Human) GRP78, a 78KDa Glucose-regulated chaperone protein, is a member of Hsp70 family of heat shock proteins. It is a multifunctional protein consisting of an N-terminal ATPase domain and a C-terminal peptide-binding domain. It plays a vital role in ensuring Ig protein folding and maturation, maintaining permeability barrier of ER translocon during early stages of protein translocation, targeting misfolded proteins for proteasomal degradation, serving as a sensor for ER stress by regulating activation of ATF6, IRE1 and PERK and contributing to ER calcium stores. It regulates proper folding and maturation of other proteins including Prp, TSHR, apoB and LDL receptor. It translocates to the cell surface and binds to MHC class I. It also serves as a receptor for alpha2-macroglobulin-dependant signaling and for uptake of certain viruses. It might have a role as a protective factor against UVC-induced cell death.

Amino acids 17-28 (RAEEEDKKEDVG) of human BiP protein were used as the immunogen.

Application Notes
The NCBI accession number for BiP is AAF42836.  The amino acid sequence used as immunogen is 100% homologous in a broad range of species.
