Germline Transmission:  Earliest citation of germline transmission: J:66420
Parent Cell Line:  W9.5/W95 (ES Cell)
Strain of Origin:  129S1/Sv-Oca2+ Tyr+ Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA neomycin resistance cassette replaced a genomic fragment containing exons 4 and 5 and parts of exons 3 and 6. RT-PCR analysis revealed no transcript in total RNA derived from retinas of homozygous animals. Western analysis confirmed the absence of protein expression in homozygous mice. (J:66420)
