despite the availability of various alkaline phosphatase (alp) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. the glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (wga). as a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...
