PCR amplification

  • After ligation and beads purification, 22ul EB is used to elute DNA, take 20ul into tubes, take 5ul of s1-5 for PCR, use all (20ul) of s6
  • 50ul PCR reaction: 25ul Kapa HF, 1ul N2.F, 1ul N2.R7-15, 0.5ul 20X SYBR green; 10 cycles
  • beads purification: 0.7X, elute in 15ul, take 12ul
