Our Abpromise guarantee covers the use of ab58950 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 - 5 µg/ml. Detects a band of approximately 90 kDa (predicted molecular weight: 83 kDa).
IP Use a concentration of 10 µg/ml.
ICC/IF Use at an assay dependent concentration.

Cells were grown on sterile coverslips then fixed with 3.7% formaldehyde in PBS for 10 minutes and permeabilized with 0.2% Triton X-100 for 10 minutes at room temperature.

Flow Cyt Use 0.01-0.1µg for 106 cells.

ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.



  • Function

    Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.
  • Sequence similarities

    Belongs to the heat shock protein 90 family.
  • Domain

    The TPR repeat-binding motif mediates interaction with TPR repeat-containing proteins like the co-chaperone STUB1.
  • Post-translational

    S-nitrosylated; negatively regulates the ATPase activity and the activation of eNOS by HSP90AA1.
  • Cellular localization

    Cytoplasm. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

  • Overlay histogram showing HeLa cells stained with ab58950 (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 (ab58950, 0.01μg/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 IgG2a [ICIGG2A] (ab91361, 0.1μg/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.
