Beschreibung
Zusammenfassung:	The invention discloses a nanometer antibody for resisting a B cell growth stimulating factor and a use thereof and belongs to the field of biotechnology. The nanometer antibody for resisting a B cell growth stimulating factor has an amino acid sequence shown in the formula of SEQ ID NO. 1 in the sequence table. Through screening of multiple nanometer antibodies with high activity and a latent neutralising capacity, the nanometer antibody 52 for resisting BAFF is obtained. The nanometer antibody can specifically bond with a human BAFF antigen, adjust biological activity of the BAFF antigen and related ligands, and effectively inhibit bonding of the BAFF antigen and its acceptors and production of corresponding signal cascade effects. The nanometer antibody for resisting BAFF can block combination of BAFF and its three related receptors, can substantially inhibit B cell proliferation or viability and can be used for detection and /or treatment on a plurality of BAFF expression abnormity-related diseases.
