YB Rapid Ligation Kit

Yeastern’s yT4 DNA ligase catalyzes the joining of two strands of DNA between the 5′ – phosphate and the 3′ – hydroxyl groups of adjacent nucleotides in either a cohesive-ended or blunt-ended termini. The enzyme also repairs single-strand nicks in duplex DNA, RNA or DNA/RNA hybrids. YB Rapid Ligation Kit is designed for efficient ligation of DNA inserts into vectors in just 5 minutes.
  • Either sticky- or blunt-end, ligation can be achieved within 5 minutes
  • The reaction mixture can be used directly for bacterial transformation
  • Join double-strand DNA with cohesive or blunt termini
  • Join oligonucleotide linkers to DNA sequence with the blunt end
  • Repair nicks in duplex DNA, RNA, or DNA-RNA hybrids
