Part:BBa_K3781012
mCerulean, MocloMania B4
This part codes for the cyan fluorescent protein mCerulean.[1] The protein was originally derived from the green fluorescent protein GFP which was first isolated from the bioluminescent jellyfish Aequorea victoria in 1962.[2] It can be fused to a protein of interest, making it accessible to easy and non-invasive screening opportunities that involve fluorescence monitoring, such as fluorescence spectroscopy or microscopy.[3]
size 26.8 kDa
function fluorescent tag
excitation wavelength 435 nm
emission wavelength 477 nm
cloning position B4
plasmid backbone pAGM1299 (BBa_K3781103)
Data
The MocloMania collection
This basic part is part of the MocloMania collection, the very first collection of genetic parts specifically designed and optimized for Modular Cloning assembly and recombinant protein expression in the protozoan parasite Leishmania tarentolae.
Are you trying to express complexly glycosylated proteins? Large antibody side chains? Human proteins that require accurate post-translational modification? Then Leishmania might be just the right organism for you! Leishmania tarentolae’s glycosylation patterns resemble those of human cells more closely than any other microbial expression host, while still delivering all the benefits of microbial production systems like easy transfection and cultivation.[4] So instead of relying on mammalian cell lines, try considering Leishmania as your new expression host of choice!
Our MocloMania collection will allow you to easily modify your protein of choice and make it suitable for downstream detection and purification procedures - all thanks to the help of Modular Cloning. This cloning system was first established by Weber et al. in 2011 and relies on the ability of type IIS restriction enzymes to cut DNA outside of their recognition sequence, hereby generating four nucleotide overhangs.[5] Every basic part in our collection is equipped with a specified set of overhangs that assign it to its designated position within the reading frame. These so-called cloning positions are labelled B2-B5 from upstream to downstream. By filling all positions with the basic parts of your choice, you can easily generate variable genetic constructs that code for the fusion protein of your desire.
We furthermore provide a specifically domesticated Leishmania expression vector, named weird_plex, which will package your fusion construct into a functional transcriptional unit that is optimized for high expression in Leishmania.
The best part? Because of the type IIS restriction properties and the specifity of the generated overhangs, restriction and ligation of your construct can all happen simultaneously in a simple one-step, one-pot reaction. This will safe you a lot of time and frustration in your cloning endeavours!
Do we have your attention? Feel free to check out our wiki to find more information on Leishmania and Modular Cloning as well as to understand how this basic part integrates into our part collection. See you there!
