Application Abreviews Notes
WB Use a concentration of 0.5 - 1 µg/ml. Detects a band of approximately 40 kDa (predicted molecular weight: 38 kDa).
IP Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration.
Flow Cyt Use 0.1µg for 106 cells. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


  • FunctionInteracts with HSP70 and can stimulate its ATPase activity. Stimulates the association between HSC70 and HIP.
  • Sequence similaritiesContains 1 J domain.
  • Cellular localizationCytoplasm. Nucleus. Nucleus > nucleolus. Translocates rapidly from the cytoplasm to the nucleus, and especially to the nucleoli, upon heat shock.

Anti-Hsp40 antibody [3B9.E6] images

  • Overlay histogram showing HeLa cells stained with ab78437 (red line). The cells were fixed with 80% methanol (5 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 (ab78437, 0.1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
