  • 特性和用法

    单位定义

    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 HaeIII restriction endonuclease.

    反应条件

    1X HaeIII Methyltransferase Reaction Buffer
    Supplement with 80 µM S-腺苷甲硫氨酸(SAM)
    Incubate at 37°C

    1X HaeIII Methyltransferase Reaction Buffer
    50 mM Tris-HCl
    50 mM NaCl
    10 mM DTT
    (pH 8.5 @ 25°C)

    对照保护实验

    HaeIII Methyltransferase is incubated with 1 µg of λ DNA in 10 µl of 1X HaeIII Methyltransferase Reaction Buffer, supplemented with 80 µM S-adenosylmethionine, for one hour at 37°C followed by 15 minutes at 65°C. The extent of protection is determined by the addition of 40 µl NEBuffer 2.1 and 10 units of HaeIII restriction endonuclease. Incubation for 1 hour at 37°C is followed by analysis on an agarose gel.
