Status | Available to order |
EMMA ID | EM:00030 |
International strain name | B6.129-B2mtm1Unc H2-Ab1tm1Doi/DoiOrl |
Alternative name | beta2m°, Abeta°(MHC) |
Strain type | Targeted Mutant Strains : Knock-out |
Allele/Transgene symbol | B2mtm1Unc, |
Gene/Transgene symbol | B2m |
Information from provider
Provider | Diane MATHIS |
Provider affiliation | LGME Universite |
Phenotypic information | Double-mutant mice deficient in products of beta-2 microglobulin, and histocompatibility 2, class II antigen A, beta 1 (MHC class I and II) genes. Obtained by crossing of strains carrying the B2m and H2-Ab1 gene mutations. They generally show a deficiency in T lymphocytes (CD4 and CD8 compartments). |
Breeding history | 129P2/OlaHsd and 129S2/SvPas ES cells; 9 generations of backcross to C57BL/6, then intercross. |
