PP2 (Src Family Kinase Inhibitor) provides a potent, cell-permeable small-molecule inhibitor for investigating Src family tyrosine kinase signaling and related cellular processes. This pyrazolopyrimidine compound inhibits Src family kinases, including Src, Fyn, and Lck, by targeting their ATP-binding sites. Researchers use PP2 to study signal transduction, cell proliferation, migration, adhesion, and kinase-dependent cellular responses.

- Mechanistic Cell Biology: Helps researchers examine the involvement of Src family kinases in cellular differentiation, survival, and other biological processes.
Storage and Handling
- Storage: Store the solid compound at −20°C in a dry, tightly sealed container, protected from light and moisture, unless the product-specific certificate or manufacturer instructions indicate otherwise. Avoid repeated temperature fluctuations and prolonged exposure to ambient conditions.
- Handling: Prepare stock solutions using a compatible solvent, such as DMSO, after confirming product-specific solubility. Dilute into suitable experimental media and maintain consistent final solvent concentrations across treatment and control groups. Determine working concentrations and exposure times according to the experimental system. PP2 also inhibits certain non-Src kinases, so use complementary controls or orthogonal approaches when interpreting target-specific effects.
