Additional Information
Gene ID 3303;3304
Positive Control Recombinant human HSP70
Application & Usage Western blot analysis (1-2 µg/ml). However, the optimal conditions should be determined individually. The antibody is specific for the inducible form of Hsp70 (Hsp72) and does not cross-react with the constitutive Hsc70 (Hsc73).
Other Names Heat shock 70 kDa protein 1A/1B, Heat shock 70 kDa protein 1/2, HSP70-1/HSP70-2, HSP70.1/HSP70.2, HSPA1A, HSPA1, HSPA1B
Target/Specificity HSP70
Antibody Form Liquid
Appearance Colorless liquid
Formulation 100 µg (0.5 mg/ml) affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 0.5% BSA, and 0.01% thimerosal.
Handling The antibody solution should be gently mixed before use.
Reconstitution & Storage -20 °C
Background Descriptions
PrecautionsHSP70 antibody is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Synonyms HSPA1, HSX70
Function In cooperation with other chaperones, Hsp70s stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. In case of rotavirus A infection, serves as a post-attachment receptor for the virus to facilitate entry into the cell. Essential for STUB1-mediated ubiquitination and degradation of FOXP3 in regulatory T-cells (Treg) during inflammation (PubMed:23973223).
Cellular Location Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs
Tissue Location HSPA1B is testis-specific.

Hsp70, one class of stress proteins, is comprised of multiple members, all of which bind ATP in vitro, but are localized within different intracellular compartments. These include: a) the constitutive Hsc70 (or cognate) present within the cytosol/nucleus; b) the highly stress-inducible Hsp70 present within the cytosol/ nucleus/nucleolus; c) the constitutive glucose regulated 78 kDa (or BiP) protein present within the lumen of the endoplasmic reticulum; and d) the glucose regulated 75 kDa protein present within the mitochondria. Hsp70 is typically not expressed in the cell under normal growth conditions, but is expressed at high levels in the cell experiencing stress. Consequently, detection of Hsp70 using an antibody specific for the inducible form is quite useful in ascertaining whether a stress response has occurred in the cell. It should be noted, however, that there is a constitutive level of Hsp70 expression in some cell types such as primates, e.g., human and monkey. Nevertheless increased expression of Hsp70 is observed in such cells following stress.
