Biological Activity

PP 2 is a selective inhibitor of Src-family tyrosine kinases. Inhibits p56lck and p59fynT (IC50 values are 4 and 5 nM respectively). Displays > 10000-fold selectivity over ZAP-70 and JAK2. Moderately inhibits CSK (IC50 = 0.73 μM).

Negative Control also available.

Technical Data

Soluble to 25 mM in DMSO with gentle warming and to 10 mM in ethanol with gentle warming
Desiccate at +4°C
