The present invention provides a polypeptide, a polypeptide composition, a kit and related applications. The polypeptides are shown in SEQ ID NO: 1 to SEQ ID NO: 85, and can specifically bind to the following target antibodies: human SNRPC/U1C antibody, human PCNA antibody, human CENPB antibody, human NUP210/gp210 antibody , Human FTCD/58K Golgi protein antibody and GAD antibody. The above-mentioned multiple polypeptides or polypeptide sets that specifically bind to the target antibody may cover peptide segments including linear epitopes and non-linear epitopes, so it is convenient to reasonably select the number of polypeptides to be used according to the actual number of target antibodies to be detected. , which can not only improve the detection sensitivity and specificity of each polypeptide, improve the detection accuracy, but also improve the throughput and efficiency of the detected antibody. |
