The Thermo Scientific™ HhaI Restriction Enzyme is a high-quality endonuclease that recognizes and cleaves DNA at the sequence GCG^C. Optimized for reliable performance, HhaI operates best at 37°C using the Tango buffer and is a critical tool for molecular biology applications such as cloning, genotyping, and restriction mapping.
Key Features:
- Recognition and Cleavage Site:
- Recognizes the palindromic sequence GCG^C and generates a 4-base sticky end.
- Cleavage produces cohesive ends ideal for cloning and other downstream applications.
- Optimized Buffer System:
- Works efficiently in Tango buffer, a universal buffer compatible with many enzymes for convenient double-digestion protocols.
- High Quality:
- Manufactured under stringent quality controls to ensure consistent activity and specificity.
- Methylation Sensitivity:
- Sensitive to CpG methylation, allowing selective digestion of unmethylated DNA.
- Not sensitive to Dam or Dcm methylation.
- Convenient Packaging:
- Supplied at a concentration of 10 U/µL, with a total of 2,000 units per vial.
Applications:
- Molecular Cloning:
- Facilitates the creation of recombinant DNA by generating compatible cohesive ends for ligation.
- Restriction Site Mapping:
- Identifies and maps restriction sites in DNA for sequencing or structural studies.
- Genotyping:
- Detects polymorphisms in DNA sequences for genetic analysis.
- Southern Blotting:
- Prepares DNA samples for hybridization and probe detection.
- RFLP (Restriction Fragment Length Polymorphism):
- Analyzes genetic variations by comparing fragment patterns after digestion.
- SNP (Single Nucleotide Polymorphism) Detection:
- Identifies single base changes in DNA sequences through digestion patterns.
