How do I design my CRISPR-Cas12a (Cpf1) crRNA guide sequence—correct orientation & strand?
Enter the 20–24 base DNA sequence downstream (3’ end) of the target Cas12a (Cpf1) PAM site (TTTV*), and then you are ready to continue. We typically recommend using a 21-nucleotide guide sequence.
The ordering tool will automatically convert the DNA sequence to RNA during the ordering process. If you are pasting your Cas12a (Cpf1) target site from an online design tool, make sure to verify the correct strand orientation before pasting the target sequence.
