| Product Name | Fast Restriction Enzyme DraIII (Recognition Site: CACNNN/GTG) |
| Catalog No. | IVDRM-0035 |
| Description | This fast restriction enzyme DraIII is a recombinant enzyme produced by genetic engineering that completes precise DNA cleavage within 5–15 minutes. It is well suited for rapid digestion of plasmid DNA, PCR products, and genomic DNA. A single universal digestion buffer is shared across the fast enzyme series, greatly simplifying reaction setup. With generous activity redundancy, the enzyme readily handles excess substrate and difficult templates. |
| Intended Use | Rapid digestion of plasmid DNA, PCR products, and genomic DNA in molecular cloning and molecular biology workflows. |
| Principle / Technology | DraIII is a type II restriction endonuclease that recognizes the degenerate sequence 5'-CAC(N)3/GTG-3' and cleaves double-stranded DNA at defined positions for downstream cloning and analysis. |
| Sample Type | Plasmid DNA, PCR products, genomic DNA. |
| Performance Range / Specifications | Complete digestion within 5–15 minutes; good activity redundancy allows digestion of excess substrate or difficult templates. |
| Specificity | Recognizes and cleaves at 5'-CAC(N)3↓GTG-3' / 3'-GTG↑(N)3CAC-5'. |
| Reaction Conditions / Protocol | 1× universal fast digestion buffer; incubate at 37°C. |
| Storage Conditions | Store at -25 to -15°C. |
| Shelf Life | 2 years when stored at -25 to -15°C. |
| Package Specifications | 30 T |
| Concentration | 20 U/μL |
| Activity / Unit Definition | 20 U/μL |
| Source / Origin | Recombinant enzyme produced by genetic engineering. |
| Expiration Date / Stability | Stable for 2 years at -25 to -15°C. |
| Recommended Buffer System | 1× universal fast digestion buffer shared across the fast restriction enzyme series, simplifying multi-enzyme reaction setup. |
| Recognition Site | 5'-CAC(N)3↓GTG-3' 3'-GTG↑(N)3CAC-5' |
| Heat Inactivation | Cannot be heat inactivated; terminate the reaction by phenol-chloroform extraction or column purification. |
| Methylation Sensitivity | CpG, EcoKI: cleavage affected EcoBI: cleavage blocked Dam, Dcm: no effect |
