Design Notes

The biobrick is constructed by two PCR’s on a commercially bought plasmid pKDsgRNA-p15 and a Gibson Assembly. The primers used were the following:

1rst PCR:

forward primer 5’ -  tttataacctccttagagctcga - 3’ 
reverse primer 5’ - tgcatccactaaagttaccg gttttagagctagaaatagcaag - 3’ 

Second PCR:

forward primer 5’ - ccaattgtccatattgcatca 3’ 
reverse primer 5’ - cggtaactttagtggatgcaggtgctcagtatctctatcactga - 3’. 

The sequence of the protospacer is highlighted in bold.

A Gibson Assembly was done with both PCR fragments and the resulting plasmid was transformed in E. coli DH5alpha and recovered on LB with 60 ng/µl spectinomycin. The plasmid was confirmed by sequencing.
