The B6 Albino model was developed by Taconic. The Tyr mutation is a constitutive knock in of a point mutation in which a G nucleotide located at position 369 in exon 1 has been replaced with C nucleotide, resulting in an amino acid substitution at position 103 (Cys>Ser). The F3 site flanked selection marker was removed by via Flp recombinase. This mutation was made in the C57BL/6NTac substrain. The line was intracrossed to homozygosity.
Use the Taconic B6 Albino as a blastocyst donor for agouti JM8A3 ES cells. Use of the Taconic B6 Albino as a blastocyst donor for JM8A3 ES cells permits detection of germline transmission by coat color in 100% of pups. G1 germline pups are heterozygous at one or two coat color loci.
