Yes, we can help you visualize protein expression using fluorescent protein tagging and epitope tagging. • In zebrafish, fluorescent proteins are added using CRISPR/Cas9 gene editing technology. You can choose from a variety of proteins including YFP, BFP, GFP, and mCherry. • Epitope tags in zebrafish are also added using CRISPR/Cas9 gene editing technology. The addition of an epitope tag at the endogenous locus enables you to quantify your protein without altering the level of gene expression. You can choose from a variety of tags including FLAG, HA, HIS, TAP, or S-peptide. Custom tags and combinations (i.e. GFP::3xFLAG, etc) are also available.
