Depositor Comments

Linker between sfGFP and iCre-ERT2 is a mutated P2A sequence where 2 conserved amino acids are changed to Alanines. This mutated sequence does not skip.

The sfGFP fluorescence from the sfGFP-iCre-ERT2 is dim, as described in Nam and Capecchi, 2020 ( and a Figshare page ( Thus, the sfGFP fluorescence should be detectable only in cells in which the marker gene expression level is high.

Homology arms subcloned from a clone of RPCI-24 C57BL/6J mouse genomic DNA library.

Please make sure the plasmid DNA preparation is pure by gel electrophoresis before linearizing for an electroporation.
