Frequently asked questions
What does DraI recognize?
DraI recognizes the 6 bp sequence TTTAAA (5′→3′), cutting the top strand between position 3 and 4 within the site to leave a blunt.
What buffer should I use for DraI?
rCutSmart gives the highest activity (incubate at 37°C).
Does DraI have star activity?
No documented star activity under standard reaction conditions.
Is DraI blocked by DNA methylation?
Not blocked by Dam, Dcm, or CpG methylation.
Can I heat-inactivate DraI?
Yes — 65°C for 20 minutes.
