These vectors can be used to
tag endogenous genes and simultaneously introduce a selection marker for screening modified strains.
Efforts to
tag endogenous genes for proteins in these compartments using CRISPR systems should strongly consider using moxFPs over standard FPs for the reasons listed above.
Another way to dodge cellular variation observed in mammalian cells is to
tag an endogenous gene.

gene, such as the introduction of heterozygous
endogenous epitope
tags, or the introduction of dominant mutations of a
gene into the
endogenous allele in cultured cells.

tags into the
endogenous alleles of the p53 and PTEN tumor suppressor
genes in human cells (Kim et al 2008).
