生物活性

Tyr-α-CGRP (human) TFA is an N-terminally extended human α-CGRP analog. Tyr-α-CGRP (human) TFA can bind to membrane preparations from rat brain and spleen with IC50 values of 0.2 nM and 0.5 nM, respectively, and induce positive chronotropic and inotropic effects in isolated guinea pig right and left atria with EC50 values of 282 nM and 74 nM, respectively. Tyr-α-CGRP (human) TFA also inhibits contractile responses in rat vas deferens with an EC50 value of 1.9 nM[1][2].

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.
