Product details:
Abcam’s HSP70 High Sensitivity in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of HSP70 in serum and plasma samples from human, mouse and rat origin. It does not detect other Hsp70 family members such as Hsc70 (Hsp73), Grp78, DnaK (E. coli), or Hsp71 (M. tuberculosis).
A HSP70 mouse monoclonal antibody has been precoated onto 96-well plates. Standards or test samples are added to the wells, incubated and then washed. A HSP70 polyclonal antibody is then added, incubated and washed. An HRP conjugated anti-IgG antibody is then added, incubated. The plate is washed once more and the TMB substrate is then added which HRP catalyzes, generating a blue coloration after incubation. A stop solution is added which generates conversion to yellow color read at 450 nm which is proportional to the amount of analyte bound.

HSP70 is a molecular chaperone whose expression is induced upon exposure of the cell or organism to conditions of stress. It prevents protein aggregation and promotes the refolding of proteins that become damaged in response to environmental insults, pathogens, and disease. Its activity is essential for cellular survival and recovery under stress conditions, as well as for the maintenance of normal cellular function under non-stress conditions. HSP70 has been implicated to play a role in a variety of disease and physiological processes such as hyperthermia, hypertension, toxic exposure to chemical agents, hypoxia, ischemia, inflammation, autoimmunity, apoptosis, cancer, organ transplantation, and bacterial and viral infections. HSP70 is also a key regulator of many normal physiological processes including aging, spermatogenesis, menstruation, and physical activity such as exercise. The HSP70 high sensitivity ELISA kit is designed to evaluate and monitor HSP70 in these processes, providing a key research tool to understand the role of HSP70 in physiology and disease.

HSP70 also known as Heat Shock Protein 70 is a highly conserved molecular chaperone with a mass of approximately 70 kDa. The protein plays an important role in maintaining protein homeostasis by assisting in the proper folding of nascent and stress-denatured proteins. It is ubiquitously expressed in the cytoplasm and mitochondria of both prokaryotic and eukaryotic cells. The expression of HSP70 rapidly increases in response to stressors such as heat infection and inflammation providing a protective mechanism for the cell.
Biological function summary
Heat Shock Protein 70 assists in the protection of cells from protein aggregation and assists in the degradation of unstable proteins. As part of a larger molecular chaperone complex HSP70 interacts with co-chaperones like HSP40 and Bag1 to mediate these functions. Its role extends to modulating apoptosis and initiating repair mechanisms under cellular stress. The balance between its anti-apoptotic and pro-survival functions is essential in cell survival during stress conditions.
Pathways
Heat Shock Protein 70 participates significantly in the cellular stress response and protein repair pathways. It integrates into the protein quality control pathway where it collaborates with other chaperone proteins such as HSP90. This coordination ensures proper protein folding and prevents aggregation therefore maintaining cell function and integrity. Additionally HSP70 is involved in the NF-kB signaling pathway regulating stress-induced transcription factors and influencing inflammation and immune responses.
Heat Shock Protein 70 has connections to cancer and neurodegenerative diseases. In cancer HSP70 proteins can support tumor growth by inhibiting apoptosis and may contribute to resistance against chemotherapy. They interact notably with proteins like p53 in this context. While in neurodegenerative diseases like Alzheimer's HSP70 aids in preventing the aggregation of neurotoxic proteins such as tau and amyloid-beta therefore potentially slowing disease progression. Understanding these interactions emphasizes the duality of HSP70 as both protective in normal cells and potentially harmful in pathological states.
