Usage and Biology

The Secreted Alkaline Phosphatase (SEAP) is an hydrolase enzyme which removes phosphate moieties from a wide range of molecules. It's build in the human placenta. A big advance is its auomatic excetrion into the extracellulare environment. This was achieved by a single amino acid mutation from L to R near the C-Terminus[Y]. SEAP is an ideal reporter protein for many applications. We used for an assay with para-Nitrophenylphosphate to measure the efficiency of our transfections and transductions by colour change and measurement of the absorption. Alternativly it's used to prevent DNA from self-ligating by removing the phosphate group or replace it with a radioactive version if radiolabeld DNA is need [X].
