General description
In SDS gels, the product reacts with both Regan and Nagao isozymes of human placental alkaline phosphatase (hPLAP, 130 kDa, 67/130 kDa). By RIA, the antibody binds to hPLAP with an affinity constant of 5 × 109 LM-1. It does not react with PLAP-like enzymes.
Monoclonal Anti-Human Placental Alkaline Phosphatase (mouse IgG2a isotype) is derived from the 8B6 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from immunized BALB/c mice. Placental alkaline phosphatase (PLAP) or ALPP is a phosphomonoesterase. It is expressed in the placenta and endometrium. The PLAP gene is localized on human chromosome 2q37.1. Small amounts of hPLAP are found in the endocervix, fallopian tubes and lung. Very small amounts of heat-stable AP resembling hPLAP (hPLAPlike AP) are expressed in the testis, thymus and in rare colon epithelial cells.
Immunogen
Human epidermoid carcinoma cell line expressing placental alkaline phosphatase.
Application
Anti-Alkaline phosphatase human placental antibody coupled to agarose was packed in a column and used to purify alkaline-phosphatase conjugated FGF receptor out of conditioned media from COS-7 cells. Column was washed with 1M NaCl.
Cultured pancreatic islet cells were fixed with cold 4% paraformaldhyde at room temperature for 10 minutes and incubated with mouse monoclonal anti-Alkaline Phosphatase, Human Placental antibody at 1:500. Mouse monoclonal anti-Alkaline Phosphatase, Human Placental antibody was used to detect a unique molecular probe that consisted of the FGFR extracellular domain expressed as a chimera with human PLAP.
Monoclonal Anti-Alkaline Phosphatase, Human Placental antibody produced in mouse has been used in:
- enzyme-linked immunosorbent assay (ELISA)
- immunocytochemistry
- radio-immunolocalization
- western blot
- immunofluorescence
- immunohistochemistry
Biochem/physiol Actions
Placental alkaline phosphatase (PLAP) or ALPP is a hydrolase, which is involved in the hydrolysis of phosphomonoesters. It has been shown to be a biomarker for ovarian cancer. The protein is expressed in carcinomas such as ovarian adenocarcinoma, dysgerminoma, serous cystadenocarcinoma and undifferentiated carcinoma. Although hPLAP has been analyzed as a potential tumor marker, it has not been widely used in the routine clinical laboratory because of its low overall specificity due to heat-inactivation, cross-reactivity with intestinal AP and L-phenylalanine sensitivity. The use of monoclonal antibodies as reagents has greatly improved the sensitivity, reproducibility and accuracy of the tests used to distinguish placental isozymes from their tumor cell counterparts. Thus, monoclonal anti-alkaline phosphatase may be useful as diagnostic tools for tumor detection.
