The application of a simple, sensitive disc assay for sialyltransferase activity to particulate and soluble enzyme preparations and its use in measuring enzymatic activity in human plasma samples. 1979

J P Durham, and D Gillies, and A Baxter, and R O Lopez-Solis

A simple assay for the determination of sialyltransferase activity is described. The method involves the isolation of the radioactive reaction product on cellulose paper discs washed with trichloroacetic acid, thereby greatly facilitating the handling of large numbers of assays. This procedure is both more accurate and more sensitive than that involving precipitation with protein denaturants and separation by centrifugation, and is applicable to both soluble and particulate enzyme preparations. The application of the method to the determination of sialytransferase in human plasma is detailed. Enzyme activity is elevated two-fold in both cancer patients and patients with non-malignant disease. This suggests that the diagnostic use of determinations of sialyltransferase activity may be limited by its non-specificity.

D003933	Diagnosis	The determination of the nature of a disease or condition, or the distinguishing of one disease or condition from another. Assessment may be made through physical examination, laboratory tests, or the likes. Computerized programs may be used to enhance the decision-making process.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012799	Sialyltransferases	A group of enzymes with the general activity CMP-N-acetylneuraminate:acceptor N-acetylneuraminyl transferase. They catalyze the transfer of N-ACETYLNEURAMINIC ACID from CMP-N-ACETYLNEURAMINIC ACID to an acceptor, which is usually the terminal sugar residue of an oligosaccharide, a glycoprotein, or a glycolipid.

D014166	Transferases	Transferases are enzymes transferring a group, for example, the methyl group or a glycosyl group, from one compound (generally regarded as donor) to another compound (generally regarded as acceptor). The classification is based on the scheme "donor:acceptor group transferase". (Enzyme Nomenclature, 1992) EC 2.	Transferase
