Anti-P101-PI3K antibodies enable researchers to detect and measure the P101-PI3K antigen in biological samples. This target is a reported synonym of the PIK3R5 gene, which encodes phosphoinositide-3-kinase regulatory subunit 5. This protein is known to function in GPCR signaling pathways and immune response pathways, among other biological roles. The human version of P101-PI3K has a canonical amino acid length of 880 residues and a protein mass of 97.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells. Other names for this target antigen include F730038I15Rik, FOAP-2, and P101-PI3K. Indicated applications for P101-PI3K antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunofluorescence, and Immunohistochemistry.
