Anti-CF2 antibodies are used in antigen-specific immunodetection in biological samples. The target CF2 is a known alias name of the protein ATPase H+ transporting accessory protein 1, encoded by the ATP6AP1 gene in humans. This 470-amino acid residue protein is reported to be an accessory subunit the proton-transporting vacuolar (V)-ATPase protein pump, which is required for luminal acidification of secretory vesicles. It is localized to the cytoplasmic vesicles and ER of the cell and features N-glycosylated post-translational modifications. In terms of tissue expression, it is found to be widely expressed, with highest levels in the brain and lowest in the liver and duodenum. Other synonyms for CF2 include 16A, ATP6IP1, and ATP6S1. Indicated applications for CF2 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
