Thermo Scientific™ FastDigest SmaI

The FastDigest SmaI restriction enzyme recognizes CCC^GGG sites and cuts best at 37°C in 5-15 minutes using universal FastDigest Buffer (isoschizomers: TspMI, XmaCI; neoschizomer: XmaI).

5' CCC ↓ GGG 3'

3' GGG ↑ CCC 5'

FastDigest enzymes are an advanced line of fast restriction enzymes that are all 100% active in the universal FastDigest and FastDigest Green reaction buffers.

The universal buffer allows rapid single-, double- or multiple-DNA digestion within 5-15 minutes, eliminating any need for buffer change or subsequent DNA clean-up steps. DNA modifying enzymes, such as Klenow Fragment, T4 DNA ligase, alkaline phosphatases, and T4 DNA polymerase all have 100% activity in FastDigest Buffer. Therefore, enzymes for downstream applications can be directly added to the FastDigest reaction mix.

For additional convenience FastDigest Green Buffer includes a density reagent and two tracking dyes for direct loading of digestion reaction products on gels.

Short incubation times and optimal composition of the universal FastDigest Buffer eliminate star activity effects.
