Anti-P85B antibodies enable researchers to detect and measure the P85B antigen in biological samples. This target is a reported synonym of the PIK3R2 gene, which encodes phosphoinositide-3-kinase regulatory subunit 2. This protein is known to function in B cell differentiation and insulin signaling pathways, among other biological roles. The human version of P85B has a canonical amino acid length of 728 residues and a protein mass of 81.5 kilodaltons. It is reported to be widely expressed in many tissue types. Other names for this target antigen include MPPH and MPPH1. Western Blot is a widely used application for the P85B antibodies listed below. In addition, Immunohistochemistry is also a common application.
