STOCK Axd/Cnrm
Status | Available to order |
EMMA ID | EM:02424 |
International strain name | STOCK Axd/Cnrm |
Alternative name | BALB/c - Axial defects |
Strain type | Spontaneous |
Allele/Transgene symbol | Axd |
Gene/Transgene symbol | Axd |
Information from provider
Provider | Madeleine BROUNS |
Provider affiliation | Maastricht University |
Genetic information | Unknown. |
Phenotypic information | All homozygotes display curled tails and/or spina bifida. 40% of heterozygotes displays curled tails. Homozygous animals have reduced fertility. |
Breeding history | Rederived heterozygous Axial defects mice were crossed 3 consecutive times with BALB/c while selecting the dominant curled tail phenotype. Genetic background was monitored using polymorphic marker analysis. This speed congenics protocol resulted in 95% BALB/c genetic background as assessed by 63 markers evenly spread over the genome. Currently the strain is bred as a heterozygous line, maintained by crosses with wild type mice of the same genetic background. Heterozygotes are identified by their curled tail phenotype. |
