75752550100100
Unit definition One unit is defined as the amount of enzyme required to hydrolyze completely a unique site 5`-G(5mC)NG(5mC)-3`/3`-(5mC)GN(5mC)G-5` in 1 μg of linearized plasmid pFsp4HI3/DriI in 1 hour at 37°C in a total reaction volume of 50 μl. As a result a linearized plasmid pFsp4HI3 disappears (see run 4 in the figure). GluI digestion of recognition sequences with three 5-methylcytosines results in additional bands appearance (runs 4-6 in the figure). GluI activity assay on DNA pFsp4HI3/DriI Lanes: 1 and 6 - 1 Kb SE DNA-markers. 2 - Control DNA pFsp4HI3/DriI, 3 - 0.5 μl Glu I 4 - 1 μl Glu I 5 - 2 μl Glu I Products were separated in 1,4% agarose gel in Buffer TAE.
Assayed on DNA pFsp4HI3/DriI is a linearized plasmid pFsp4HI3, which carries a gene of DNA-methyltransferase M.Fsp4HI and includes a unique GluI site:5`-G(5mC)NG(5mC)-3`/3`-(5mC)GN(5mC)G-5` [2].
Storage conditions 10 mM KH 2 PO 4 (pH 7.45); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA, 50% glycerol; Store at -20°C.
Ligation
Nonspecific hydrolysis No detectable degradation of 1μg of Lambda DNA was observed after incubation with 1 units of enzyme for 16 hours at 37°C in a total reaction volume of 50 μl.
Methylation sensitivity The enzyme cleaves C5-methylated DNAand does not cut unmodified DNA [1].
Supplied with enzyme 10 X SE-buffer Y
Notes When using a buffer other than the optimal (suppied) SEBuffer, it may be necessary to add more enzyme to achieve complete digestion.
