we have expressed a recombinant mouse interferon alpha ( r.mu-ifn alpha 2 ) in escherichia coli under the control of a tryptophan promoter using a synthetic adaptor formed by annealing two partially complementary oligonucleotides which introduced an atg start codon and re-established the complete coding sequence of the mature ifn alpha 2 protein in the expression vector .
