The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/1000 - 1/10000. Detects a band of approximately 29 kDa (predicted molecular weight: 29 kDa).
1/1000 - 1/2000. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
The 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.
Belongs to the peptidase T1A family.
Cytoplasm. Nucleus. Cytoplasm, P-body. Colocalizes with TRIM5 in the cytoplasmic bodies.
Immunohistochemical analysis of paraffin-embedded, Human papillary adenocarcinoma of thyroid tissue labeling PSMA4 with ab191403 at a 1/2000 dilution (1μg/ml). Counter stained with hematoxylin. In the negative control PBS was used instead of primary antibody.
Immunohistochemical analysis of paraffin-embedded, mouse liver tissue labeling PSMA4 with ab191403 at a 1/2000 dilution (1μg/ml). Counter stained with hematoxylin. In the negative control PBS was used instead of primary antibody.
Immunofluorescence analysis of, paraformaldehyde-fixed, HeLa cells labeling PSMA4 with ab191403 at a 1/500 dilution ( 4 ug/ml). As secondary antibody goat anti-rabbit IgG (Alexa Fluor®488) ab150077 was used at a 1/200 dilution. In blue DAPI staining. In the negative controls cells were treated with anti-PSMA4 at a 1/500 dilution as primary antibody and goat anti-mouse IgG (Alexa Fluor®594) at a 1/400 dilution as secondary antibody.
Western blot analysis on immunoprecipitation from 1) Jurkat cell lysate and 2) PBS, labeling PSMA4 using ab191403 at 1/200 dilution and HRP-conjugated anti-rabbit IgG preferentially detecting the non-reduced form of rabbit IgG at a 1/1500 dilution.
