The Generation of Mice Homozygous for a Disrupted Ndfip1 Gene
(A) The location of the gene trap vector within the Ndfip1 locus is shown. The Ndfip1 locus contains 8 exons spanning about 45 Kb of genomic DNA.
(B) The gene trap vector was inserted into the second intron and results in the production of a truncated Ndfip1 mRNA that encodes exons 1 and 2.
(C) Offspring resulting from the intercross between Ndfip1+/− mice were tested by PCR to identify Ndfip1−/− animals via the primer pairs shown in Figure 1A.
(D) To confirm the disruption of Ndfip1, RNA was isolated from Ndfip1+/+ and Ndfip1−/− mice and RT-PCR was performed. We detect the presence of two transcripts in Ndfip1−/− tissues, Ndfip1-AST and Ex2-βGEO. GADPH is shown as a reverse transcriptase and loading control.
