Zusammenfassung:PROBLEM TO BE SOLVED: To produce the subject antibody having high purity suitable for an experimental reagent or a clinical application by applying a gene recombination technique by using a host Escherichia coli. SOLUTION: This recombinant-type anti-human TNF-α human monoclonal antibody is composed of an H chain having an amino acid sequence of formula I and acting as an H chain of anti-human TNF-α human monoclonal Fab antibody and an L chain having an amino acid sequence of formula II and acting as an L chain of anti-human TNF-α human monoclonal Fab antibody. The recombinant-type anti-human TNF-α human monoclonal antibody is obtained by selecting and collecting a cDNA of the human antibody from a human B lymphocytes cell producing an anti-human TNF-αhuman antibody such as an anti-human TNF-α human monoclonal antibody producing 1D5 strain (EBV transformed B lymphocytes oligo clone), introducing the cDNA into a manifestation vector producing a human Fab antibody in an Escherichia coli by a gene recombination and culturing its transforming bacterium.
