General description

Monoclonal Anti-PSMB9 (mouse IgG2a isotype) is derived from the hybridoma LMP2-37 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with human PSMB9 recombinant protein. Proteasome 20S subunit beta 9 (PSMB9) is present in the major histocompatibility complex (MHC) class II region. γ-interferon triggers the synthesis of three proteasomal subunits-PSMB9 (β1i), PSMB10 (β2i) and PSMB8 (β5i), which is a part of immunoproteasome.


human PSMB9, recombinant protein.


Monoclonal Anti-PSMB9 antibody produced in mouse has been used in:
• flow cytometry
• enzyme linked immunosorbent assay (ELISA)
• immunoblotting
• immunocytochemistry

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Biochem/physiol Actions

Proteasome 20S subunit beta 9 (PSMB9) is used during antigen presentation. Aberrant levels of PSMB9 is involved in autoimmune disorders such as primary Sjogren′s syndrome and uterine leiomyosarcomas. The proteasome is a multicatalytic proteinase complex, which is involved in the regulation of essential cellular processes such as transcription, cell cycle progression, differentiation, apoptosis and in the control of stress and immune responses.
