| molecularNote | A puromycin resistance gene cassette with a 5' loxP site was inserted into exon 1 and 2 of the Igh Cmu gene segment, deleting 330bp of 3' of exon 1, intron 1 and 5' of exon 2. This insertion was done in ES cells that already had a neo cassette with a 3' loxP site in the alpha 3' enhancer of Igh Calpha (Rr151). |
