Human Hsp90 alpha
Our Abpromise guarantee covers the use of ab79849 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use 1µg for 106 cells.
ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
|IHC-Fr||Use at an assay dependent concentration.|
|IHC-P||Use a concentration of 0.5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
|ELISA||Use at an assay dependent concentration.|
|WB||1/2000. Predicted molecular weight: 85 kDa.|
|IP||Use at an assay dependent concentration.|
|ICC||Use at an assay dependent concentration.|
|ICC/IF||Use at an assay dependent concentration.|
Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: Hsp90 alpha knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lanes 1 - 3: Merged signal (red and green). Green - ab79849 observed at 90 kDa. Red - loading control, ab181602, observed at 37 kDa.
ab79849 was shown to specifically react with Hsp90 alpha in wild-type HAP1 cells as signal was lost in Hsp90 alpha knockout cells. Wild-type and Hsp90 alpha knockout samples were subjected to SDS-PAGE. Ab79849 and ab181602 (Rabbit anti GAPDH loading control) were incubated overnight at 4°C at 1/2000 dilution and 1/20,000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) secondary antibodies at 1/20,000 dilution for 1 hour at room temperature before imaging.
IHC image of Hsp90 alpha staining in Human Testis formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab79849, 0.5 µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
