Staurosporine (Stsp) is potent inhibitor of protein kinase C (PKC) from rat brain, exhibiting an IC50 value of 2.7 nM.1 It inhibits rat recombinant PKC-α approximately 100- and 1,000-fold better than PKC-δ and PKC-ζ, respectively.2 However, Stsp is non-selective in that it also inhibits the activity of a variety of other protein kinases, not only PKC isoforms.3 The biological effects of Stsp include cytotoxicity, relaxation of smooth muscle, and regulation of eNOS gene expression.3,4

Cayman Chemical Company regularly evaluates our shipping methods to ensure product stability is maintained and our corporate environmental impact is minimized. Products selected for review are evaluated and shipping methods are certified by our Scientists. While occasionally our method of shipping a product may change, rest assured the shipping conditions on all Cayman Chemical products have been reviewed and validated.
Upon receipt, it is important to check the storage requirements of your products and place them at the appropriate temperature. Products shipped without ice may require frozen storage for long term stability.
Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
