Immunofluorescent analysis of Heat Shock Protein 70 (HSC70) (green) in HeLa and NIH3T3 cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 1% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed with a HSC70 monoclonal antibody (Product # MA3-014) at a dilution of 1:50 for at least 1 hour at room temperature, washed with PBS, and incubated with DyLight 488 goat anti-mouse IgG secondary antibody (Product # 35502) at a dilution of 1:400 for 30 minutes at room temperature. Nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan at 20X magnification.

MA3-014 detects heat shock cognate protein 70 kDa (HSC70) from human, feline, primate, rat, and mouse tissues. This antibody displays slight cross-reactivity to HSP70.
MA3-014 has been successfully used in Western blot, immunohistochemistry, immunofluorescence, and immunoprecipitation procedures By Western blot, this antibody detects a 70 kDa protein representing HSC70. By 2D gel electrophoresis, MA3-014 was found to bind strongly to HSC70 and faintly to HSP70 both before and after heat shock. Immunohistochemical staining of HSC70 in mouse spermatids/spermatozoa with MA3-014 results in staining restricted to the post acrosomal region in condensing spermatids and to the midpiece in spermatozoa.
The MA3-014 antigen is mouse spermatogenic cell protein.
The HSP70 family is a set of highly conserved proteins that are induced by a variety of biological stresses, including heat stress, in every organism in which the proteins have been examined. The human HSP70 family members include: HSP70, a protein which is strongly inducible in all organisms but which is also constitutively expressed in primate cells; HSP72, a 72 kDa protein that is induced exclusively under stress conditions; HSC70, or cognate protein, is a 72 kDa, constitutively expressed, protein which is involved in the uncoating of clathrin coated vesicles; GRP78, or BiP, is a glucose regulated 78 kDa protein localized in the endoplasmic reticulum; and p75, or HSP75, a 75 kDa protein that is found within the mitochondria.
HSC70 (also known as HSC71, HSC73, HSP73, p72, prp73) is expressed constitutively and is slightly heat-inducible. HSC70 binds to the exposed loop of clathrin light chains to promote uncoating and can also bind the cytoskeleton which may facilitate cytoskeletal rearrangements. HSC70 has been shown to stimulate lysosomal degradation of intracellular proteins and to retard both aggregation and folding of mitochondrial precursor proteins in vitro.
