RPSA Antibody / 40S Ribosomal protein SA

• Catalog Number: orb534304
• Category: Antibodies
• Description: Required for the assembly and/or stability of the 40S ribosomal subunit. Required for the processing of the 20S rRNA-precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits. Also functions as a cell surface receptor for laminin. Plays a role in cell adhesion to the basement membrane and in the consequent activation of signaling transduction pathways. May play a role in cell fate determination and tissue morphogenesis. Acts as a PPP1R16B-dependent substrate of PPP1CA. [UniProt]
• Clonality: Monoclonal
• Species/Host: Mouse
• Isotype: Mouse IgG
• Conjugation: Unconjugated
• Reactivity: Human
• Immunogen: Recombinant full length protein was used as the immunogen for the RPSA antibody.
• UniProt ID: P08865
• Tested applications: FACS, IF, IHC-P, WB
• Dilution range: Immunofluorescence: 1-2ug/ml,Flow cytometry: 1-2ug/million cells,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT,Prediluted IHC only format: incubate for 30 min at RT (1)
• Application notes: The stated application concentrations are suggested starting points. Titration of the RPSA antibody may be required due to differences in protocols and secondary/substrate sensitivity.1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
