Design Notes

The sequence to this part was adapted from a Chlamy-optimized plasmid, in which it contained a RBCS2 intron. We thus had to design special primers that would render the genetic regions upstream and downstream of the intron as individual parts via PCR. These then could be re-assembled into an intact mCerulean gene with the help of invertedly oriented BbsI restriction sites introduced with the primers. Due to the high resemblence in codon usage between Chlamydomonas reinhardtii and Leishmania tarentolae, the codons were not further optimized.


Source

The sequence was directly derived from the plasmid pCM0-081 of the MoClo Toolkit distributed by Crozet et al.[1] The protein is a mutated version of the cyan fluorescent protein ECFP which in itself is derived via mutagenesis from the green fluorescent protein avGFP isolated from the jellyfish Aequorea victoria.[2] mCerulean's genetic sequence can be found in the Addgene Plasmid #27796.[3]
