Method for Selecting Antibody-Producing Cell Line, and Kit Thereof

A method for selecting antibody-producing cell lines, comprising:

• transfecting a first expression vector and a second expression vector into cells, wherein the first expression vector comprises a sequence which encodes a first fragment of a fluorescent protein and a sequence which encodes a heavy chain of an antibody, and the second expression vector comprises a sequence which encodes a second fragment of the fluorescent protein and a sequence which encodes a light chain of the antibody;
• and
• selecting the antibody-producing cell lines by confirming fluorescence derived from reassembly between the first fragment and the second fragment of the fluorescent protein.
