Part:BBa_K2492002

To indicate neuron AWA in C.elegans’(Caenorhabditis elegans) head, we chose mCherry. We found that the part BBa_K2005050 is mCherry submitted by iGEM16_Vanderbilt. However, their mCherry was not designed for C.elegans.

So, we got the sequence and improved it with C.elegans codon adaptor ^[1]. Compared with original mCherry, new synthesized mCherry sequence is modified in two ways, three introns were added, and the codons were modified(Figure 1).

The mCherry part we using now is optimized for C.elegans. We added the characterization to part page since the original part has no visual characterization neither on part page nor on their wiki. However, our mCherry is expressed in C.elegans. Plate reader and flow cytometer are not available for fluorescence measurement. To confirm the position of neuron AWA in C.elegans’ head. We observe C.elegans with a confocal microscope(Figure 2). The whole neuron with dendrite can be observed distinctly. The branch of dendrite near the mouse can be observed as described in wormatlas.
