Technical Data
MvaI (EcoRII*)
Molecular Biology Storage: -20CShipping: Blue Ice
5'-C C^A G G-3'
3'-G G T^C C-5'

MvaI-neoschizomer of EcoRII, produces DNA fragments that have a
1-base 5'-extension. Unlike EcoRII, MvaI is not blocked by Dcm methylation.

E.coli that carries the cloned mvaIR gene from Micrococcus varians RFL19

Concentration: 10u/ul

Unit Definition:
One unit is defined as the amount of M9580 required to digest 1ug of lambda DNA in 1 hour at 37C in 50ul of assay buffer.

Supplied in 10mM Tris-HCl, pH 7.5, 400mM KCl, 1mM DTT, 0.1mM EDTA, 0.2mg/ml BSA and 50% glycerol.

Supplied With:
R1625: Restriction Enzyme Buffer A, 10X: Supplied as a liquid in 33mM Tris-acetate, 10mM magnesium acetate, 66mM potassium acetate, 0.1mg/ml BSA (pH 7.9 at 37C).

R1625-04: Restriction Enzyme Buffer E, 10X: Supplied as a liquid in 10mM Tris-HCl, pH 8.5, 10mM MgCl2, 100mM KCl and 0.1mg/ml BSA. Incubate at 37C.

Dilute with: 10mM Tris-HCl, pH 7.4, 100mM KCl, 1mM EDTA, 1mM DTT, 0.2mg/ml BSA and 50% glycerol.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, aliquot and store at -20C. Stable for at least 12 months
Overdigestion Assay: No detectable change in the specific fragmentation pattern is observed after 80-fold overdigestion (5u/ug lambda DNA x 16 hours) with M9580.

Stability during Prolonged Incubation: A minimum of 0.1 units of MvaI is required for complete digestion of 1ug of lambda DNA in 16 hours at 37C.

Ligation/Recutting Assay: After 10-fold overdigestion (0.6u/ug DNA x 17 hours) with M9580, more than 90% of the DNA fragments can be ligated in a reaction mixture containing 20-40u of T4 DNA ligase/1g of fragments and 10% PEG at a 5'-termini concentration of 0.6uM. More than 90% of these sites can be recut.

Labeled Oligonucleotide (LO) Assay:
No detectable degradation of a single-stranded and double-stranded labeled oligonucleotide was observed after incubation with 10 units of MvaI for 4 hours.

Thermal Inactivation: Not activated by incubation at 80C for 20min.

Compatible Ends: Satl, Bme1390I
