General description
Alkaline phosphatase, placental type (UniProt: P05187; also known as EC:3.1.3.1, Alkaline phosphatase Regan isozyme, Placental alkaline phosphatase 1) is encoded by the ALPP (also known as PLAP) gene (Gene ID: 250) in human. Placental alkaline phosphatase (ALPP) is a metalloenzyme belonging to the alkaline phosphatase family. It is characterized by its ability to hydrolyze phosphate monoesters, a function essential for various biological processes including dephosphorylation reactions. ALPP forms a homodimer, each monomer containing a catalytic site that binds one magnesium and two zinc ions. It is anchored in the plasma membrane by a phosphatidylinositol-glycan moiety (PI-glycan) that is added to the nascent peptide chain after the removal of 29 amino acids from the COOH-terminus. ALPP is predominantly expressed in placental trophoblasts. It is upregulated in alcohol-related liver disease and in certain cancers, such as ovarian, colon, non-small lung cancer and testicular germ cell tumors. ALPP is used as a prognostic marker in pancreatic adenocarcinoma and a target for cancer immunotherapy. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.
Immunogen
KLH-conjugated linear peptide corresponding to 16 amino acids from the C-terminal half of human ALPP.
Application
Quality Control Testing
Evaluated by Western Blotting in human placenta tissue lysate.
Western Blotting Analysis: A 1:1,000 dilution of this antibody detected ALPP in human placenta tissue lysate.
Tested Applications
Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected ALPP in human placenta tissue sections.
Affinity Binding Assay: A representative lot of this antibody bound with ALPP peptide with at least one thousand-fold (1,000X) higher affinity than with non-specific control peptide.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Biochem/physiol Actions
Clone 1B5 is a ZooMAb® rabbit recombinant monoclonal antibody that detects ALPP. It targets an epitope within 16 amino acids from the C-terminal half.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
