表位
Epitope mapping with a panel of HSP 70 deletion mutants suggests that the epitope recognized is located between amino acids 122-264 of human HSP 70, a region that has been shown to be involved in ATP binding. This is the first monoclonal antibody reported to react with: 1) The ATP binding region of HSP 70. 2) An epitope in the amino terminus of HSP 70. -

Primary antibody说明
The HSP 70 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 HSP 70 family members include: HSP 70, a protein which is strongly inducible in all organisms but which is also constitutively expressed in primate cells; HSP 72, a 72 kDa protein that is induced exclusively under stress conditions; HSC 70, or cognate protein, is a 72 kDa, constitutively expressed, protein which is involved in the uncoating of clathrin coated vesicles; GRP 78, or BiP, is a glucose regulated 78 kDa protein localized in the endoplasmic reticulum; and p75, or HSP 75, a 75 kDa protein that is found within the mitochondria. -

Function: In cooperation with other chaperones, the Hsp70 family 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. Tissue specificity: HSPA1B is testis-specific. -

Immunofluorescent analysis of U-251 MG (Human brain glioma cell line) cells labeling Hsp70 (green) with ab2787. F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with or an antibody recognizing Heat Shock Protein 70 ab2787 at a dilution of 1/100-1/200 over night at 4oC washed with PBS and incubated with a DyLight-488 conjugated secondary antibody. Images were taken at 60X magnification.

Immunohistochemistry was performed on normal biopsies of deparaffinized Human tonsil tissue. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1/200 with a mouse monoclonal antibody recognizing Heat Shock Protein 70 (ab2787) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Overlay histogram showing Jurkat cells stained with ab2787 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2787, 1:100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1:500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 80% methanol (5min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Immunoprecipitation of Hsp70 was performed on HeLa (Human epithelial cell line from cervix adenocarcinoma) whole cell lysate. Antigen:antibody complexes were formed by incubating 500µg whole cell lysate with 2µg of ab2787 overnight on a rocking platform at 4°C. The immune complexes were captured on 50µl Protein A/G Agarose, washed extensively, and eluted with buffer. Samples were then resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBST for at least 1 hour. The membrane was incubated with ab2787 (1:1000) overnight rotating at 4°C, washed in TBST, and probed with IP detection reagent-HRP at a dilution of 1:1000 for at least one hour. Chemiluminescent detection was performed.

ab2787 staining human skin. Staining is localized to the cytoplasm and nucleus.
Left panel: with primary antibody at 1/100. Right panel: isotype control.
Sections were stained using an automated system at room temperature. Sections were rehydrated and antigen retrieved. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required. -
