W. Jeong et Hc. Shin, SUPPLY OF THE ARGU GENE-PRODUCT ALLOWS HIGH-LEVEL EXPRESSION OF RECOMBINANT HUMAN INTERFERON-ALPHA-2A IN ESCHERICHIA-COLI, Biotechnology letters, 20(1), 1998, pp. 19-22
Escherichia coli BL21 (DE3) co-transformed with the gene of human inte
rferon-alpha 2a (IFN-alpha 2a) and the argU gene that codes for minor
tRNA(Arg(AGG/AGA)) produced IFN-alpha 2a in yield of more than 25% of
the total cellular proteins. IFN-alpha 2a was purified from insoluble
inclusion bodies as much as 10 mg per liter of LB culture and the meth
ionine residue at the N-terminus was found to be completely processed.
