Background strain C57BL/6JJcl  
 1 Appearance black  
Genotype No Data  
Strain development Developed by Dr. Masazumi Takahashi. This strain has been introduced into C57BL/6 genetic background by successive backcrossing for more than 10 generations in RIKEN Tsukuba Institute.  
Strain description The acetylcholine receptors are known to have important roles in neuro-muscular functions. The gamma subunit are expressed in embryonic stages and the epsilon subunit are expressed postnatal stages.
The acetylcholine receptors gamma and epsilon subunits have been disrupted by homologous recombination to study the functions of these genes and switching mechanism of gamma to epsilon subunits. The gamma subunit deficient homozygotes died after two days post delivery, suffering from inability of motor function of the limbs and drinking milk. The analysis on the neuro-muscular junctions showed the structural and electrophysiological abnormalities.  
Colony maintenance Backcrossing to C57BL/6. Or sister-brother mating of heterozygotes. Breeding performance is good.
