In Vitro

Pentagastrin (ICI-50123) (0.1-100 μM; GH3-cells) increases intracellular Ca2+ in a dose-dependent manner with a maximal increase of 2.77-fold[1].
Pentagastrin (ICI-50123) (0.1-100 μM; GH3-cells) bounds dose dependently to GH3 cells[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.
