Recombinant Human PIK3CA/PIK3R1, His-tagged, Active

• Cat.No.: PIK3CA/PIK3R1-389H
• Product Overview: Recombinant human full-length p110α (E545K) mutant subunit and human p85α wild-type subunit were co-expressed by baculovirus inSf9 insect cellsusing an N-terminal His tag on both proteins. MW=111 kDa (p110α), ~86 kDa (p85α).

Specification

• Species: Human
• Source: Sf9 Cells
• Tag: His
• 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.
• Sequence: Full-length.
• Applications: Kinase Assay, Western Blot.
• Storage And Stability: Store product at –70°C. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
