We've made a VP22/Cre recombinase fusion protein. Our initial attempt
at getting Cre-mediated recombination using murine embryonic stem cells
containing a loxP-flanked exon resulted in 3 out of 23 cell lines with
recombination. Far from the 100% advertised, but it was also our first
attempt. I'm sure we'll get close to 100% with a few more
