Abstract
Antigenic proteins may be expressed in bacteria by use of vectors having inserted therein DNA fragments from an envelope gene. The DNA fragments employed in the example are coding sequences found in the HTLV-I envelope gene. The bacteria used was E. coli. The antigenic proteins are useful in identifying antibodies to the organisms from which the DNA fragments were originally obtained.
