| 5-T G A T C A-3 3-A C T A G T-5 Concentration: 10u/ul Source: Bacillus caldolyticus Buffer: 10mM Tris-HCl (pH 7.5), 10mM MgCl2, 50mM NaCl and 0.1mg/ml BSA. Incubate at 55C. Incubation at 37C results in 50% activity. Diluent Buffer: 10mM Tris-HCl (pH 7.4 at 25C), 100mM KCl, 1mM EDTA, 1mM DTT, 0.2mg/ml BSA and 50% glycerol. Storage Buffer: 10mM Tris-HCl (pH 7.4 at 25C), 100mM KCl, 1mM DTT, 1mM EDTA, 0.2mg/ml BSA and 50% glycerol. Overdigestion Assay: No detectable change in the specific fragmentation pattern is observed after 80-fold overdigestion (5u/ug lambda DNA x 16 hours) with BclI (see Star Activity). Ligation/Recutting Assay: After 50-fold overdigestion (3u/ug DNA x 17 hours) with BclI, more than 90% of the DNA fragments can be ligated at a 5-termini concentration of 0.1uM. More than 90% of these can be recut. Labeled Oligonucleotide (LO) Assay: No detectable degradation of a single-stranded and double-stranded labeled oligonucleotide was observed after incubation with 10units of restriction endonuclease for 4 hours. Blue/White Cloning Assay: The mix of pUC57/HindIII, pUC57/PstI and pUC57/Eco32I digests was incubated with 10units of enzyme for 16 hours. After religation and transformation 0.3% of white colonies were detected. Star Activity: A large excess of enzyme (7.5u/ug DNA x 16 hours) may result in star activity. Star activity appears at 10-fold overdigestion (10 units x 1 hour). Methylation Effects: BclI cuts neither TGm6ATCA nor TGAThm5CA, but cuts TGATm5CA. Blocked by Dam methylation. Stability during Prolonged Incubation: A minimum of 0.1unit of enzyme is required for complete digestion of 1ug of lambda DNA in 16 hours at 55C. Thermal Inactivation: Only small amounts of enzyme (up to 10units) can be inactivated at 80C for 20min. Compatible Ends: BamHI, BglII, Bsp143I, MboI, PsuI Number of Recognition Sites in DNA: Lambda: 8 PhiX174: 0 M13mp18/19: 0 pBR322: 0 pUC18/19: 0 pUC57: 0 pTZ19R/U: 0 pBluescriptIIKS(-/+): 0 pBluescriptIISK(-/+): 0 pACYC177: 0 pACYC184: 1 Unit Definition: One unit is defined as the amount of enzyme required to digest 1ug of lambda DNA dam-in 1 hour at 55C in 50ul of assay buffer. |
