HLA-B50 (B50) is an HLA-B serotype. B50 is a split antigen from the B21 broad antigen, the sister serotype B49.[1] The serotype identifies the more common HLA-B*50 gene products.[2] (For terminology help see: HLA-serotype tutorial)
Serotype
| B*50 | B50 | B21 | Sample |
| allele | % | % | size (N) |
| 5001 | 85 | 3 | 1700 |
The B*5002 by serotype definition is a B45 serotype.[4]
