METHOD AND KIT FOR PREPARING ANTIBODY PAIR AND USE OF KIT, AND SYSTEM FOR PREPARING ANTIBODY PAIR

摘要

The application discloses a method, kit and system for preparing an antibody pair, and the use of the kit. Wherein the method comprises using an antigen-binding fragment of an existing antibody as a capture antibody and using an anti-crystallizable fragment antibody as a labelled antibody to directly screen a target antibody which can be paired with the existing antibody from cell culture supernatant. By using the technical solution of the present application, the cell culture supernatant can be directly screened to obtain the antibody pair without requiring a large-scale preparation, purification and labelling of the antibody to be screened, thereby greatly reducing the workload.
