Webbalso used similar methods to determine CreC2#4 (a Cre mutant) and VCre (a Cre homolog). In contrast to zinc ﬁnger and TAL eﬀector domains, no modular decomposition of DNA speciﬁcity exists for Cre recombinase homologs. As a result, the RT speciﬁcity of Cre has previously been modiﬁed using directed evolution, a laborious … Webb19 mars 2015 · We stably transduced two murine tumor cell lines with a retroviral or lentiviral vector expressing Cre recombinase alone or in combination with GFP.
