Research Abstract

It is known that the structure of oligosaccharide existed in glycoproteins and cell membrane frequently mutate in cancer cells. It was found that the structure of oligosaccharide in glycoprotein α-fetoprotein from serum was varied in hepatoma patients. Therefore, we intended to develop a simple method to prepare the monoclonal antibody specific for the mutagenic oligosaccharide of glycoprotein. In this study, we synthesized the novel glycoconjugate (alkylglycoside) having oligosaccharide of glycoprotein as immunogen using transglycosylation activity of microbial endoglycosidase (endo-β-N-acetylglucosaminidase), and prepared the monoclonal antibody against asparagine-linked bianntenary complex-type of oligosaccharide.
1. We prepared a large amount of glycopeptide containing bianntenary complex-type of oligosaccharide from hen egg yolk as the donor of ligosaccharide for binding to alkylgucoside.
2. We synthesized alkylglycoside as the immunogen of asparagine-linked bianntenary complex-type … More of oligosaccharide using transglycosylation activity of Mucor endoglycosidase (Endo-M). We incubated egg yolk glycopeptide and n-octyl-β-D-glucoside with Endo-M, pH6.0, at 37℃ for 12hr, and isolated the transglycosylation product by HPLC. The product was confirmed as the alkylglycoside having complex-type of oligosaccharide by mass spectrometry.
3. We immunized mice by the alkylglycoside. The immunogen was injected to mice intraperitonealy four times. After last booster, spleen cells were harvested and mixed with myeloma cells, and fused. Three weeks later, hybridomas grew and the screening of hybridomas producing antibody against oligosaccharide was carried out by ELISA method using human serum tranferrin glycopeptide and egg yolk glycopetide, both of which contained bianntenary complex-type of oligosaccharide. As the result, five hybridoma cell lines were obtained as the producer of antibody. Using these hybridomas, cloning was carried out by limiting dilution method. Then, we obtained three hybridoma clones which produced antibody against bianntenary complex-type of oligosaccharide.
4. We also prepared the hybridoma producing asialo-bianntenary complex-type of oligo-saccharide according to the same method described above. Less
