I am trying to knockout huntingtin gene from HeLa cells (human epithelial cells). I used CRISPR explorer and benchling.com to determine the best guide RNA sequence that would bind to the target DNA sequence and cas9 could then make the cut. The gRNA I have is as follows:
GGAGGCCTCGGGCCGACTCG Strand (-)
The next step for me is to design the primers with the following sticky ends
Forward primer: 5'-TTGTTGN(19)-3' Backward primer: 3'-ACN(19)AAA-5'
The problem I'm having is writing the oligonucleotide sequence of the primers. Since the gRNA strand is negative, I'm assuming it's a 3'-5' sequence, hence the reverse of it will be the 5'-3' sequence, which I can then just use as the forward primer. Sequentially, I can take the reverse and complement of this forward primer sequence to then determine the backward primer. Is that correct? I appreciate all your help.
