  Flow Cytometry - Anti-Hsp70 antibody [5A5] (ab2787)

  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 22°C. The secondary antibody used was DyLight^® 488 goat anti-mouse IgG (H+L) (Goat Anti-Mouse IgG H&L (DyLight® 488) preadsorbed ab96879) at 1:500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (Mouse IgG1, Kappa Monoclonal [B11/6] - Isotype Control 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 - Anti-Hsp70 antibody [5A5] (ab2787)

  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.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Hsp70 antibody [5A5] (ab2787)

  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.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Hsp70 antibody [5A5] (ab2787)

  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.
