Caracteristici standard:
| Product Name | FseI |
| Concentration: | 2,000 units/ml |
| Unit Definition: | One unit is defined as the amount of enzyme required to digest 1 µg of pBC4 DNA in 1 hour at 37°C in a total reaction volume of 50 µl. |
| Shelf Life: | 12 months |
| Storage Temp: | -80 °C |

| Specification Version: | PS-R0588S/L v2.0 |
| Effective Date: | 17-Dec-13 |
| Endonuclease Activity (Nicking) | - A 50 µl reaction in CutSmart™ Buffer containing 1 µg of supercoiled PhiX174 DNA and a minimum of 10 Units of FseI incubated for 4 hours at 37ºC results in |
| Exonuclease Activity (Radioactivity Release) | - A 50 µl reaction in CutSmart™ Buffer containing 1 µg of a mixture of single and doublestranded [ ³H] E. coli DNA and a minimum of 10 units of FseI incubated for 4 hours at 37ºC releases |
| Ligation and Recutting (Terminal Integrity) | - After a 10-fold over-digestion of pBC4 DNA with FseI, >95% of the DNA fragments can be ligated with T4 DNA ligase in 16 hours at 16ºC. Of these ligated fragments, >95% can be recut with FseI. |
| Non-Specific DNase Activity (16 Hour) | - A 50 µl reaction in CutSmart™ Buffer containing 1 µg of pBC4 DNA and a minimum of 10 units of FseI incubated for 16 hours at 37ºC results in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis |
| Protein Purity Assay (SDS-PAGE) | - FseI is >95% pure as determined by SDS PAGE analysis using Coomassie Blue detection. |
