Bu-1a/b antibody | AV20
Mouse anti ChickenBu-1a/b antibody, clone AV20 (MCA5764) used to identify Bu-1 expressing cells in chicken conjunctiva associated lymphoid tissue by immunofluorescence.
Image caption:
Cellular infiltrates of head-associated lymphoid tissues following vaccination with BeauR-M41(S1) and BeauR-QX(S1). Cryosections were stained with monoclonal antibodies to detect Bu-1+ (green) and CD8α+ (red) cells. Nuclei were labeled with DAPI (blue). Scale bars, 50 μm. Representative images are shown in all panels.

Antibody Quality and 
Unrivaled 
| Mouse anti ChickenBu-1a/b antibody, clone AV20 recognizes Chicken Bu-1a/b, also known as chB6, a type 1 transmembrane protein. Bu-1 is a product of two alleles, Bu-1a ad Bu-1b, clone AV20 recognises both alleles. The Bu-1 antigen is expressed by chicken B-cells throughout most of their development and by a subset of monocytes and macrophages. The antigen is absent from erythrocytes, granulocytes and thrombocytes. In addition to clone AV20, clone L22 that recognises Bu-1a but not Bu-1b is available. |
