General description

Alkaline phosphatase (ALP) is a hydrolase enzyme. It is a highly active form in calf intestinal mucosa. The calf intestinal alkaline phosphatase is a dimeric glycoprotein with a molecular weight of about 140kDa.
The recombinant, highly active Alkaline Phosphatase possesses the same amino acid sequence as the native, bovine-sourced Alkaline Phosphatase. No animal-derived components are used in the production process. This eliminates the risk of Bovine Spongiform Encephalopathy (BSE) and other infections caused by animals.
The recombinant enzyme guarantees superior lot-to-lot consistency and completely eliminates the risk of BSE.

Specificity

Alkaline phosphatase catalyzed the hydrolysis of numerous phosphate esters, such as esters of primary and secondary alcohols, saccarides, cyclic alcohols, phenols and amines. Phosphodiesters do not react. The enzyme hydrolyzes inorganic pyrophosphate. The kinetic properties of the enzyme depend on many factors, such as enzyme purity, enzyme concentration in the assay, buffer, pH etc.

Application

Alkaline Phosphatase can be coupled to other proteins via its amino and carbohydrate groups. The enzyme solution can be used directly for conjugation without prior dialysis. For conjugation of AP with IgG, a ration of 2.5:1 is recommended. The application of the conjugated enzyme varies from ELISAs and microarrays to western blot analysis.

Biochem/physiol Actions

Alkaline phosphatase (ALP) is responsible for removing phosphate groups at the 5- and 3- positions from many types of molecules, such as nucleotides, proteins, and alkaloids. It can also modify lipopolysaccharides by dephosphorylation of the lipid A moiety, thereby making it less toxic than the unmodified lipid A.

Minor changes in the quality of biologically manufactured monoclonal antibodies (mAbs) can affect their bioactivity and efficacy. One of the most important variations concerns the N-glycosylation pattern, which directly affects an anti-tumor mechanism called antibody-dependent cell-meditated cytotoxicity (ADCC). Thus, careful
