General description

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with mouse myleloma cells. Recognizes the ~29-32 kDa α1, 2, 3, 5, 6 and 7 subunits of the 20S proteasome.

Recognizes α1, 2, 3, 5, 6 and 7 subunits of 20S proteasome in human placental proteasome preparations.

This Anti-20S Proteasome alpha-1, 2, 3, 5, 6, & 7 Subunits Antibody is validated for use in WB, IP, ELISA, IF, ICC and IHC for the detection of 20S Proteasome alpha-1, 2, 3, 5, 6, & 7 Subunits.


Epitope: within the prosbox I motif common to α subunits (TVWSPQGRLHQVEYAMEA)

dinitrophenylated proteasomes


Immunoblotting (1:1000, chemiluminescence)

Immunoprecipitation (not recommended)

ELISA (see comments)

Immunofluorescence (see application references)

Immunocytochemistry (see application references)

Immunohistochemistry (see application references)

Frozen Sections (see application references)


100 μL in Plastic ampoule


Toxicity: Highly Toxic (H)

Analysis Note

Positive Control
Human placental tissue

Other Notes

Immunoblotting using a human placental proteasome preparation yields two bands at ~29 kDa and ~32 kDa. In ELISA the antibody reacts with the peptide sequence TVWSPQGRLHQVEYAMEA encompassing the prosbox I motif common to α-type subunits. Antibody should be titrated for optimal results in individual systems.
