Abstract
The N-acetylglucosaminyltransferase III activity is enhanced in a cell carrying retrovirus-origin gag-pol gene and env gene. By constructing a retrovirus vector with the use of the above cell, a retrovirus vector having a modified sugar chain structure can be obtained. The retrovirus vector constructed by this method shows a high infection efficiency particularly in the presence of a functional substance.
