InactiveCN101245107AAvoiding Immunogenicity IssuesImprove expression levelNervous disorderBacteriaSingle-Chain AntibodiesDrug administration
The invention relates to an anti-human transferrin receptor human antibody and the application, which pertains to the field of molecular biology. The anti-human transferrin receptor human antibody has a single-chain antibody (scFv) amino acid sequence which is shown in a sequence table SEQ ID No.1. The anti-human transferrin receptor human antibody and the application have the advantages that: the human antibody solves the problem of immunogenicity of the target antibody, thus allowing the human antibody to carry out the long-term repeated drug administrations in the human body; the method for screening a genetic engineering antibody in a large-capacity antibody library which is adopted by the invention is easier than the monoclonal antibody preparation, the large-scale production is easy, the molecule of the antibody is small, and the antibody can enter tissues deeply, thus having obvious advantages. A pET-22b (plus) vector which is adopted by the invention contains a stronger T7 promoter, which can ensure the higher expression level of the target antibody. The induced expression conditions after the optimization can ensure that the antibody is expressed in a soluble form and the activity of protein is higher. The 3' end of the pET-22b (plus) vector is provided with six His(histidine) labels, which can easily use the Ni-NTA agarose to carry out affinity chromatography and purification.
