Anti-p101 antibodies are used in antigen-specific immunodetection in biological samples. The target p101 is a known alias name of the protein phosphoinositide-3-kinase regulatory subunit 5, encoded by the PIK3R5 gene in humans. This 880-amino acid residue protein is a regulatory subunit of the PI3K gamma complex. It is localized to the cell membrane, nucleus, and cytoplasm of the cell. In terms of tissue expression, it is widely expressed across many tissue types. Other synonyms for p101 include F730038I15Rik, FOAP-2, and P101-PI3K. Indicated applications for p101 antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunofluorescence, and Immunohistochemistry.
