WebThe initial targeted allele containing the neo-cassette was a severe hypomorph. In vivo deletion of the neo-cassette by Flp recombinase produced a floxed allele that generates normal expression of NaV1.6 protein. Ubiquitous deletion of the floxed exon by Cre recombinase in ZP3-Cre transgenic mice produced the Scn8a(del) allele. WebFor the floxed allele genotyping (top), gDNA is PCR amplified with primers P1 and P2. The Wt allele generates a 150-bp product, whereas the floxed allele generates a 260-bp product. Genotyping gel shows Wt, heterozygous (Het), and homozygous Sbp2 floxed mice. For the null allele genotyping (bottom), gDNA is PCR amplified with primers P3, P4 ...
