Design Notes

The scaffold region has been designed as referred from Ref. 1. It consists of the tracrRNA and some regions of crRNA. The guiding region is the 20 bp spacer sequence which is complementary to the mutant katG gene in Mtb and referred from Ref 2. The mutation appears at base number 11 (agc → acc) of the spacer (guiding) sequence. This is the S315T mutation in Mtb genome (refer Ref 3).

The 20 bp spacer sequence is as follows: gcgatcaccaccggcatcga
