I am looking to use a placental alkaline phosphatase antibody for sorting syncytiotrophoblast material from female tissue. It looks like most people who use these antibodies use in-house versions and references for commercially available antibodies I've found are from the '80's. I noticed you have several different monoclonal antibodies and was hoping you could give me a little more information on them and potential applications they've been tested for. Also, do you have a biotinylated or fluorophore-conjugated version?

None of our placental alkaline phosphatase antibodies are biotinylated or fluorchrome conjugated but we offer a number of kits for this application and our lab can do a custom conjugation as well, for an additional fee. NB600-750 is useful in FACS with human cells, so I would recommend this antibody for your experiment. We back the use of this antibody as stated on the datasheet with the 100% Novus Guarantee. If you have questions about another antibody, I will be happy to answer them.

Scientific Data Images for Human Alkaline Phosphatase/ALPP Antibody

Detection of Human Alkaline Phosphatase/ALPP by Western Blot.

Western blot shows lysates of JAR human choriocarcinoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Alkaline Phosphatase/ALPP Monoclonal Antibody (Catalog # MAB59051) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Alkaline Phosphatase/ALPP at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Alkaline Phosphatase/ALPP in Human Placenta.

Alkaline Phosphatase/ALPP was detected in immersion fixed paraffin-embedded sections of human placenta using Mouse Anti-Human Alkaline Phosphatase/ALPP Monoclonal Antibody (Catalog # MAB59051) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to syncytiotrophoblast cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Detection of Human Alkaline Phosphatase/ALPP by Simple Western^TM.

Simple Western lane view shows lysates of JAR human choriocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Alkaline Phosphatase/ALPP at approximately 74 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Alkaline Phosphatase/ALPP Monoclonal Antibody (Catalog # MAB59051). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.

Background: Alkaline Phosphatase/ALPP

Four distinct genes encode alkaline phosphatases (APs) in humans. The ALPP gene encodes the 67 kDa placental isozyme, also known as PLAP. In comparison, ALPI, ALPL, and ALPPL2 encode intestinal, liver/bone/kidney, and placental-like or germ cell APs, respectively. The placental alkaline phosphatase is a glycosyl phosphatidylinositol (GPI) anchored protein that is expressed on the cell surface as a homodimer. Human APs are ectopically expressed in several cancers, and their serum levels are useful tumor markers. Mature human Alkaline Phosphatase/ALPP shares 74% amino acid sequence homology with the mouse and rat enzymes.
