Recombinant acquired immune deficiency syndrome (AIDS) viral envelope protein fragments and method of testing for AIDS

摘要

Recombinant envelope proteins of the etiologic agent of acquired immune deficiency syndrome (AIDS) useful in diagnosis and therapy of AIDS and a method for their preparation are described. Proviral DNA is transferred into a host cell after engineering into an expression vector which produces the envelope protein. A method of testing human blood for the presence of antibodies to the AIDS virus using the AIDS envelope protein is also described.
