Modified gRNA expression vector

This part is a modified version of part BBa_K3208000. This new gRNA expression vector contains red expression cassette (BBa_ K3208010) inserted between the two Eco31I sites. This allows selection of positive transformants based on colour when one uses these 2 sites for cloning of new gRNAs.

We performed 3 cloning experiments (with 3 different gRNAs that were given to us as overlapping oligos by team iGEM Bulgaria 2017) ) and we found that when using the right color as a selection tool, we increased the cloning efficiency to the range of 4-6 positive colonies per 10 white colonies. This is a huge improvement compared to the previous version (see part BBa_K2515002 for details).
