The CLIP-tag gene is available codon-optimized for mammalian expression in two formats:

The CLIP-source pCLIP10m plasmid is a high copy number storage plasmid, intended for use as a PCR template of the CLIP-tag.

The CLIP-express Mammalian Expression Plasmid is a ready to use expression plasmid containing a codon optimized gene for the CLIP-tag
