| abstract |
The present invention provides a binding polypeptide comprising a specific amino acid sequence that binds to a B lymphocyte stimulating factor (BLyS) protein or a BLyS-like polypeptide. The binding polypeptide is obtained from screening of a phage display library, and the binding polypeptide is a BLyS protein or BLyS-like polypeptide contained in a solution or mixture of blood, tissue sample, conditioned medium, or the like. Peptides are used for detection or isolation. [Selection figure] None |
