    Abstract: A method of obtaining at least one recombinant antibody with improved affinity for a selected antigen from a family of antibodies which bind the selected antigen comprising: a) obtaining a family of two or more antibodies which bind the same antigen in which the VH CDR3 amino acid sequence of each antibody in the family is the same length and greater than 60% identical at the amino acid level; b) re-pairing the VH region of an antibody obtained in step (a) with the VL region from a different antibody obtained in step (a) to produce a new recombinant antibody; and c) screening the recombinant antibody produced in step (b) and selecting said antibody if it has improved affinity for the selected antigen compared to any one of the antibodies obtained in step (a).

    Abstract translation: 一种从结合所选抗原的抗体家族获得至少一种对所选抗原亲和力的重组抗体的方法,包括:a)获得结合相同抗原的两个或多个抗体的家族,其中所述抗体的VH CDR3氨基酸 家族中每种抗体的序列与氨基酸水平相同,长度大于60%; b)将步骤(a)中获得的抗体的VH区与来自步骤(a)中获得的不同抗体的VL区重新配对以产生新的重组抗体; 和c)筛选步骤(b)中产生的重组抗体,如果与步骤(a)中获得的任何一种抗体相比,对所选择的抗原具有改善的亲和力,则选择所述抗体。
