    Abstract:
    A specific and fast method for the determination of N-acetylglucosaminyltransferase III, IV and V activity in one assay is described. The method is based on the separation by HPLC of the three transferase products formed from the common acceptor oligosaccharide substrate GlcNAc beta 1----2Man alpha 1----3(GlcNAc beta 1----2Man alpha 1---- 6)Man beta 1----4GlcNAc. Assays are not interfered with by substances that result from enzymatic or chemical breakdown of the donor substrate UDP-[14C]GlcNAc. Using this assay system N-acetylglucosaminyltransferase III, IV and V activities were estimated in Novikoff ascites tumour cells, mouse lymphoma BW 5147 cells and hen oviduct.
