Product info: FauND I Name FauND I      Cat. # E009m Package, u.a. 500 Concentration, u.a./ml 10000 Recognition site CA↑TATG GTAT↓AC Source E.coli strain that carries the cloned FauND I gene from Flavobacterium aquatili ND Assayed on Lambda DNA Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl. Reaction buffer SE-buffer Y + BSA Optimal temperature 37oC Storage conditions 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0,1 mM EDTA; 1mM DTT; 200 μg/ml BSA, 50% glycerol; Store at -20°C. Ligation After 10-fold overdigestion with enzyme 80% of the DNA fragments can be ligated and recut. In the presence of 10% PEG ligation is better. Non-specific hydrolisis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 20 u.a. of enzyme for 16 hours at 37°C. Reagents Supplied with Enzyme 10 X SE-buffer Y, BSA Inactivation 20 minutes under 65oC Notes Sensitive to impurities present in some DNA preparations. For example, DNA purified by standard miniprep procedures is cleaved at lowe rates. To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation. MSDS: Download MSDS as PDF References: Shevchenko, A.V., Belichenko, O.A., Myakisheva, T.V., Dedkov, V.S., Abdurashitov, M.A., Degtyarev, S.K.
