Calphostin I

Calphostin I is a selective protein kinase C (PKC) inhibitor with an IC₅₀ of 0.14 μM in rats. Calphostin I interacts with the regulatory domain of PKC, and the aromatic groups at its C-14 and C-17 positions contribute to enhanced potency and selectivity, with no inhibition of cyclic adenosine monophosphate-dependent protein kinase (PKA) at high concentrations. Calphostin I can be used in research related to cervical cancer and breast cancer.

In Vitro

Calphostin I potently and selectively inhibits partially purified rat brain PKC with an IC₅₀ of 0.14 μM, and does not inhibit partially purified bovine heart PKA at concentrations up to 50 μM^[1].
Calphostin I (1 h) inhibits the growth of human cervical cancer HeLa S₃ cells with an IC₅₀ of 0.24 μM and human breast cancer MCF-7 cells with an IC₅₀ of 0.16 μM in vitro^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
