| molecularNote | A genomic fragment containing most of exon 2 was replaced with a promoterless DsRed-mammalian sterile 20 cassette and a floxed neo cassette via homologous recombination. RT-PCR confirmed the absence of mRNA expression in homozygous MEFs and detected an increase in expression of Rbm4 . |
