Abstract
Objective To study the antisense oligonucleotides (antisense ODN) in down regulation of α2,6 sialyltransferase (ST6Gal I) activity and α2,6 sialylation of cell surface of Burkitt s lymphoma cell line Daudi. Methods Daudi cells were treated with modified antisense ODN in vitro, the ST6Gal I mRNA expression was examined by RT PCR, the ST6Gal I enzyme activity was measured with fluorometric sialyltransferase assay and the amount of α2,6 sialylation of cell surface was determined by FACS analysis.Resul...
