Detection of Human and Mouse Alkaline Phosphatase/ALPL by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, BG01V human embryonic stem cells, NTera‑2 human testicular embryonic carcinoma cell line, and mouse kidney tissue. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse Alkaline Phosphatase/ALPL Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2909) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Alkaline Phosphatase/ALPL at approximately 75-80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Alkaline Phosphatase/ALPL
Four distinct genes encode alkaline phosphatases (APs) in humans (1). The ALPL gene encodes the liver/bone/kidney isozyme, also known as the tissue-nonspecific AP (TNAP). In comparison, ALPI, ALPP and ALPPL2 encode intestinal, placental and placental-like or germ cell APs, respectively. The serum levels of human APs are useful tumor markers (2). There are many mutations in the ALPL gene, leading to different forms of hypophosphatasia, characterized by poorly mineralized cartilage and bones (3). The native ALPL is a glycosylated homodimer attached to the membrane through a GPI-anchor. The C-terminal pro peptide (residues 503‑524) is not present in the mature form.
