    To investigate the effect of SB431542 on the accumulation of TGFβ1 and MMP3 in MM cells, RPMI 8226 cells are treated with 10, 100 and 1,000 nmol/mL SB431542 for 48 h.

    • 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.
