High Concentration End-Repair Mix

EMOT1116

This high-concentration formulation of the End-Repair Mix is compatible with applications requiring >1 microgram of DNA to be prepared for blunt-end ligation. The mix converts DNA containing damaged or incompatible 5′- and/or 3′-protruding ends to 5′-phosphorylated, blunt-ended DNA. The conversion to blunt-ended DNA is accomplished by exploiting the 5′→ 3′ polymerase and 3′→ 5′ exonuclease activities of T4 DNA Polymerase (P7080L). T4 Polynucleotide Kinase (Y9040L) ensures that the ends of the blunt-ended DNA fragments are 5′-phosphorylated for subsequent ligation by T4 DNA Ligase (L6030-HC-L).
