摘要:
Described are novel chimeric anti-human immunodeficiency virus (HIV) antibodies which comprise a constant region derived from human antibody and variable region derived from mouse monoclonal antibody, gene fragments coding for the variable region the H and L chain of chimeric anti-HIV antibodies which are effective for expression of chimeric anti-HIV antibodies having an HIV-neutralizing activity, a transformant where such gene fragments are incorporated, chimeric anti-HIV antibodies expressed therefrom and a process for their preparation. The chimeric anti-HIV antibodies of the present invention show anti-HIV neutralizing activity and are useful for the diagnosis, treatment and prevention of acquired immunodeficiency syndrome (AIDS) caused by HIV without side effects such as anaphylactic shock or serum sickness.

摘要:
Anti-FCV (feline calicivirus) feline-type recombinant antibody effective for treatment, prevention and diagnosis of FCV infection and a gene fragment useful for preparation of said antibody are provided. Cell line lD7 capable of producing a mouse monoclonal antibody having an excellent FCV-neutralizing activity was constructed and a gene fragment coding for the V region in charge of the FCV-specific binding of said antibody was obtained. This gene fragment and the gene coding for the constant region of the feline antibody are used to give a chimeric anti-FCV recombinant antibody. The obtained recombinant antibody is a novel antibody and is useful for the diagnosis, treatment and prevention of feline virus infections, particularly feline calicivirus infection, with high safety in administration into cats.
