| Description : |
The PI3K comprises of a 110 kDa catalytic subunit and a 85 kDa regulatory subunit. A number of isoforms of the 110 kDa catalytic subunit and the 85 kDa regulatory subunit exist in cells. The p110α catalytic subunit (PIK3CA) is frequently mutated or amplified in a variety of cancers including ovarian and colon and this protein is one of the PI3K mutants. PIK3CA gene copy number is increased in over 30% of ovarian cancers and this leads to increased PI3-kinase activity. Furthermore, the activity of p110α is essential for vascular development and inactivation of p110α leads to severe defects in angiogenic sprouting and vascular remodeling. |
| Formulated In : |
25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 30% glycerol, and 3 mM DTT. |
| Specific Activity : |
130 pmol/min/μg. A unit of 110a/p85a kinase activity is defined as the amount of enzyme required to produce 1 pmol of Phosphoinositol-3, 4,5-Trisphosphate/min at 37°C. A 25 μl kinase reaction is conducted in a buffer containing 10 mM Tris-HCl (pH 7.5), 50 mM NaCl, 5 mM MgCl2, 100 μM ATP, 10 μg mix of PS and Phosphoinositol-4,5-Bisphosphate, and 50 ng enzyme for 15 minutes at 30°C. Conversion of ATP to ADP is detected using PI3K ADP-Glo® Luminescent Kinase Assay (Promega Corporation, Madison, WI). |
| Application : |
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. |
| Stability : |
>6 months at –80°C. |
