    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 1D7 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.

    摘要: The present invention relates to a gene fragment coding for a variable region of an antibody having a neutralizing activity against human immunodeficiency virus (HIV) and a process for preparing the same. A mouse-human chimeric antibody and a mouse-human reshaped antibody having a neutralizing activity against HIV can be prepared by obtaining a specific nucleotide sequence of a gene fragment coding for a variable region of H chain and L chain of an antibody having a neutralizing activity against HIV, and then artificially fusing DNAs synthesized based on these nucleotide sequences with a gene coding for a human immunoglobulin. The novel recombinant anti-HIV antibody of the present invention is useful for treatment and prevention of AIDS.

    摘要: A monoclonal antibody useful for clinical application which recognizes the conserved region of V3-PND region of glycoprotein antigen having a molecular weight of about 1.2.times.10.sup.5 daltons (gp120) on a coating membrane of human immunodeficiency virus (HIV) and which has an ability to neutralize a broad range of various HIV variants, or a fragment thereof, and the chimeric and humanized antibodies derived therefrom are provided. By using as an immunogen a plurality of peptides having PND-Tip region containing the highly conserved GPGR sequence within PND of HIV gp120, a monoclonal antibody having a neutralizing activity to many HIV variants can be prepared. By transplanting the gene fragment coding for the variable region of said monoclonal antibody or complementarity determining region (CDR) of said region to a human antibody gene, a chimeric antibody or a reshaped antibody having an anti-HIV neutralizing activity which are effective for clinical application can be obtained.
