Description

PSI (TFA) is a potent proteasome inhibitor. PSI (TFA) inhibits the proliferation of primary effusion lymphoma (PEL) cells. PSI (TFA) can be used for the research of Kaposi’s sarcoma-associated herpesvirus (KSHV) infection and KSHV-associated lymphomas[1].

IC50 & Target

CC50: 205 nM (BJAB cells); 190 nM (Ramos cells); 22.0 nM (BC3 cells); 53.0 nM (BCBL1 cells)[1]
In Vitro

PSI (TFA) (24 h) inhibits the proliferation with CC50 values of 205, 190, 22.0, 53.0 nM for BJAB, Ramos, BC3, BCBL1 cells, respectively)[1].
PSI (TFA) (50 nM; 6 h) increases caspase-3/7 activity by 8-fold compared with control[1].
PSI (TFA) (50 nM; 6 h) decreases the transcriptional activity of NF-κB by 52%[1].
PSI (TFA) (1, 5 nM; 3 days) inhibits the growth of BC3 cells at a high concentration (5 nM)[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
