Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to protect 1 µg λ DNA in 1 hour at 37°C in a total reaction volume of 10 µl against cleavage by MspI restriction endonuclease.

Reaction Conditions

1X MspI Methylase Reaction Buffer
Supplement with 640 µM S-adenosylmethionine (SAM)
Incubate at 37°C

1X MspI Methylase Reaction Buffer
50 mM Tris-HCl
100 mM NaCl
5 mM β-ME
10 mM EDTA
(pH 7.5 @ 25°C)

Control Protection Assay

One unit of MspI Methyltransferase is incubated with 1 µg of λ DNA in 10 µl 1X MspI Methylase Reaction Buffer, supplemented with 640 µM S-adenosylmethionine, for one hour at 37°C followed by 15 minutes inactivation at 65°C. The extent of protection by MspI Methyltransferase is determined by the addition of 5 units of MspI restriction endonuclease in 40 µl 1X NEBuffer 2 supplemented with 10 mM MgCl2 followed by incubation at 37°C for 30 minutes. Results are analyzed on agarose gel.

Storage Buffer

50 mM Tris-HCl
50 mM NaCl
5 mM β-ME
