FAQs
- Will the FFPE DNA Repair Mix ligate my DNA fragments?
- Will treating my DNA with the FFPE DNA Repair Mix hurt my downsteam reaction?
- Will the FFPE DNA Repair Mix blunt the ends of the DNA?
- Does the FFPE DNA Repair Mix insert random nucleotides into the sequence that it repairs?
- Does the FFPE DNA Repair Mix remove covalent modifications from DNA bases, such as methylation, biotin or digoxigenin?
- Does the FFPE DNA Repair Mix repair DNA-protein crosslinks?
- Does the FFPE DNA Repair Mix fix blocked 3’ ends?
- Can the FFPE DNA Repair Mix repair damage in both single and double stranded DNA? Or, does it require double stranded DNA as a template?
