Incomplete glycosylation of Asn 563 in mouse immunoglobulin M.
Mouse immunoglobulin IgM was prepared from MOPC 104E ascites fluid and [3H]-mannose labeled tumor cells. The purified protein was used to prepare Fc fragments which were cleaved by cyanogen bromide. Gel filtration allows complete separation of the C-terminal glycosylation site. Amino acid and carbohydrate analyses show that Asn 563 of murine IgM is glycosylated only about 44% of the time.
