生物活性

Ac-YVAD-CHO (L-709049) is a potent, reversible, specific tetrapeptide interleukin-lβ converting enzyme (ICE) inhibitor with mouse and human Ki values of 3.0 and 0.76 nM. Ac-YVAD-CHO is also a caspase-1 inhibitor. Ac-YVAD-CHO can suppress the production of mature IL-lβ[1][2][3].

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.
