  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

About PIK3CA / PI3K Alpha

P42336 NM_006218 NP_006209.2

PIK3CA Antibody, MCAP Antibody, p110-alpha Antibody, p110alpha Antibody, PI3K Antibody, PI3-kinase p110 subunit alpha Antibody, PI3-kinase subunit alpha Antibody, PI3Kalpha Antibody, MCM Antibody, MCMTC Antibody, PI3K-alpha Antibody, PtdIns-3-kinase subunit alpha Antibody, CLOVE Antibody

Phosphoinositide-3-kinase (PI3K) that phosphorylates PtdIns (Phosphatidylinositol), PtdIns4P (Phosphatidylinositol 4-phosphate) and PtdIns(4,5)P2 (Phosphatidylinositol 4,5-bisphosphate) to generate phosphatidylinositol 3,4,5-trisphosphate (PIP3). PIP3 plays a key role by recruiting PH domain-containing proteins to the membrane, including AKT1 and PDPK1, activating signaling cascades involved in cell growth, survival, proliferation, motility and morphology.


Formalin-fixed and paraffin-embedded human breast carcinoma reacted with PI3KCA Antibody , which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
