Frequently asked questions

What does SwaI recognize?

SwaI recognizes the 8 bp sequence ATTTAAAT (5′→3′), cutting the top strand between position 4 and 5 within the site to leave a blunt.

What buffer should I use for SwaI?

rNEBuffer 3.1 gives the highest activity (incubate at 25°C).

Does SwaI have star activity?

No documented star activity under standard reaction conditions.

Is SwaI blocked by DNA methylation?

Not blocked by Dam, Dcm, or CpG methylation.

Can I heat-inactivate SwaI?

Yes — 65°C for 20 minutes.
