Genotyping of B6.129S4-Pdgfratm11(EGFP)Sor/J mice (PDGFRαEGFP). Agarose gel electrophoresis of PCR products showing genotyping results for wild-type (WT) and heterozygous mice. The DNA ladder on the left indicates fragment sizes in base pairs (bp), with relevant bands at 500 and 200 bp. The WT samples show a single band consistent with the WT allele, while heterozygote samples exhibit two bands, indicating the presence of both the wild-type and mutant alleles.
