FIELD: molecular biology, genetic engineering. SUBSTANCE: invention relates to preparing the novel, original, artificially produced polypeptide consisting of product of expression of gene env HTLV-I fragment fused with E. coli beta-galactosidase and binding antibodies raised to product of gene env HTLV-I, DNA ATLE 495 fragment, strain of E. coli HB101 transformed with recombinant plasmid pATLE 495 containing DNA ATLE 495 fragment. Invention ensures to obtain 200-350 mg of hybrid protein from 1 l suspension of E. coli cells. This hybrid protein has the specific polypeptide sequence encoded by region env of genome HTLV-I and can be used for serodiagnosis of HTLV-I carrying out. EFFECT: high valuable biological properties. 4 cl, 4 ex
