Anti-Acid Phosphatase / ACP1

0.5 mg/ml with 0.1 mg/ml BSA (US sourced), 0.05% sodium azide. Acid phosphatases (AP) are a broad family of enzymes that differ widely in their AA length and homology, molecular weight and tissue of origin. They function to remove phosphate groups (or dephosphorylate) from proteins and perform best under acidic conditions. Disease states are sometimes characterized by abnormally high or low levels of Acid phosphatase, leading to them being used as serological and histological disease markers. Prostatic Acid Phosphatase (PAP) was initially used as a prostate cancer marker but was later replaced with Prostate Serum Antigen (PSA), a more sensitive early stage cancer marker. Protein function: Acts on tyrosine phosphorylated proteins, low-MW aryl phosphates and natural and synthetic acyl phosphates. Isoform 3 does not possess phosphatase activity. [The UniProt Consortium]
