Our Abpromise guarantee covers the use of ab22666 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.
|WB||1/1000. Detects a band of approximately 27 kDa.|
FunctionThe proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. PSMA2 may have a potential regulatory effect on another component(s) of the proteasome complex through tyrosine phosphorylation.
Sequence similaritiesBelongs to the peptidase T1A family.
modificationsPhosphorylated on tyrosine residues; which may be important for nuclear import.
Cellular localizationCytoplasm. Nucleus.

Overlay histogram showing HeLa cells stained with ab22666 (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 (ab22666, 1µg/1x106 cells) 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.
