A targeting vector was designed to contain the Enhanced Yellow Fluorescent Protein gene (from the pEYFP - N1 plasmid, Clonetech) downstream of a loxP - flanked stop sequence (neomycin resistance gene and a trimer of the SV40 polyadenylation sequence). (jax.org)
These mice contain an Enhanced Yellow Fluorescent Protein gene (EYFP) inserted into the Gt (ROSA) 26Sor locus. (jax.org)
To ensure that donor and host tissues could be easily distinguished, we generated EFTF - expressing cells from transgenic embryos constitutively expressing a variant of yellow fluorescent protein (Venus YFP)[10]. (journals.plos.org)
