Beschreibung

Unit definition: One unit is defined as amount of Sst I (Sac I) enzyme required to produce a complete digest of 1 µg Lambda DNA in 60 min in a total reaction volume of 50µL under the assay conditions.

Unit substrate: Lambda DNA/HindIII digest

Unit definition: One unit is defined as amount of enzyme required to produce a complete digest of 1 µg Lambda DNA in 60 min in a total reaction volume of 50µL under the assay conditions.
Unit substrate: Lambda DNA/HindIII digest
Unit calculation assay conditions: 1 µg Lambda DNA HindIII digest has been digested in 10mM Tris-HCl (pH 7.9 at 25 °C), 10 mM MgCl2, 1mM DTT, 100 µg/mL bovine serum albumin.
Absence of contaminants: 50 units of SstI do not produce any unspecific cleavage products after 16 hrs incubation with 1µg of Lambda/HindIII DNA at 37 °C. After 10-fold overdigestion with SstI, greater than 95% of the DNA fragments can be ligated and recut with this enzyme.
Storage buffer: SstI is supplied in 50 mM NaCl, 10 mM Tris HCl (pH 7.4), 0.1 mM EDTA, 1 mM DTT, 200 μg/ml BSA and 50% glycerol.
Inactivation: SstI can be heat inactivated in 20min at 65 °C. The enzyme can be removed by spin column purification. It is also possible to stop the digest by addition of EDTA to a final concentration of >10mM or SDS to a concentration of 0.1 %. Alternatively use our environmentally friendly 6x orange gel loading buffer. For further enzymatic reactions remove SDS or EDTA by spin column-based PCR purification kit.
Methylation Sensitivity:
dam methylation: Not sensitive
dcm methylation: Not sensitive
CpG Methylation: Not sensitive

The Enzyme is supplied with 10x Buffer L and the 10x universal Simple Buffer for double digests. The enzyme is also fully active in the respective buffers from other suppliers and may be used in double digests together with enzymes from other suppliers. For example, the enzyme is 100 % active in CutSmart® Buffer from NEB.
10x Buffer L: 100mM Tris-HCl (pH 7.9 at 25 °C), 100mM MgCl2, 1mg/mL BSA
10x Simple buffer: 500 mM Potassium Acetate, 200 mM Tris-acetate (pH 7.9 at 25°C), 100 mM Magnesium Acetate, 1000 μg/ml BSA

 

Rapid digest within 15 minutes.

Incubate at 37 °C for 15 minutes.

Always add the restriction enzymes as last component. Mix gently but thoroughly by pipetting up and down or flicking. Spin down. Incubate at 37 °C for 15min. Restriction enzymes are stored in 50% glycerol. The glycerol concentration in the reaction mix should not exceed 10%. When digesting more than 1µg DNA, scale up the restriction mix or prolong the incubation time.
