Product Specific Information

For maximum recovery please spin prior to use. Unless noted below, aliquots of the 5 µg, 10 µg and 20 µg sizes of kinase are not recommended as materials can be used in original packaging until exhausted. For larger sizes, the number of freeze/thaws may be reduced by preparing aliquots, aliquots below 20 µL are not recommended. Please never store a kinase diluted. If properly stored at -80C, this product is guaranteed for 6 months from date of purchase.

Target Information

PIK3CA E542K/PIK3R1 (p110 alpha E542K/p85 alpha) lipid kinase is comprised of a 110 kDa catalytic subunit and an 85 kDa regulatory subunit. A number of isoforms of the 110 kDa catalytic subunit and the 85 kDa regulatory subunit exist in cells. PIK3CA is frequently mutated or amplified in a variety of cancers including ovarian and colon and this kinase 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 PIK3CA is essential for vascular development and inactivation of PIK3CA leads to severe defects in angiogenic sprouting and vascular remodeling.
