FIG. 2.
PCR and Southern blot results for five positive ES cell subclones. A PCR genotyping of DNA from the five positive ES cell subclones carrying the Slc44a2 targeting construct (3.3-kb PCR product), subclone 78 that lacked the targeting construct, and +/+ (wild-type) mouse DNA (3.1-kb PCR product) without the construct. B Southern blot showing the presence of the Slc44a2 8.4-kb wild-type and the 6.0-kb recombinant construct in the five positive subclones of clone 29.
