| Blood and tissue typing and histocompatibility tests must be done in advance. |
| Parabiotic mice have been reported to produce stable blood chimerism across major histocompatibility barriers. |
| The purpose of this project is to examine the DRB region of the major histocompatibility complex in the owl monkey. |
| After the detection of bilateral sacroiliitis, testing for histocompatibility antigen HLA-B27 was done and results were positive. |
| Laboratories performing cytology, cytogenetics or histocompatibility testing will undergo on-site inspection every two years. |
| Nowadays compatibility is more often determined using MHC, or major histocompatibility complex. |
