Rosmarinus Sequence

GenBank: KY931461


Rosmarinus remains tetrameric and becomes dimeric only at nanomolar concentrations (∼70 nM)... Rosmarinus was made using PCR and the In-Fusion cloning technique (Clontech) to fuse the front half of the coding region for mc5 to the back half of meleCFP at a five amino acid identical stretch in their coding sequences.
