Fusion PCR (1) System The basic system is similar to common PCR. There are some notes to raise the fusion efficiency. a. Complementary region length: 15-20bp b. Raise the annealing temperature in the fusion step. (2) Program:
• Program: • 95’: 5min • 95' : 30-50sec • Tm(fu)+ (-2)~5: 40-80sec • 72' : the longer/1kb/min 10-15 cycles • 72' 5min • Add amplification Primers • 95' 2-5min • Go on under common program for 25-30 cycles
Restriction cut
Reagent Concentration/Activity Volume(50ul system)
Restriction cut buffer 10x 5ul
Enzyme 1 -- 1ul
Enzyme 2 -- 1ul
Add DNA and distilled water to 50ul.
Incubate at 37℃, 1.5 hrs or longer
(Enzymes from Takara Co., Ltd or NEB)
Ligation
Reagent Volume(10ul system)
Solution I 5ul
DNA fragment 3.5ul(changeable)
Vector 1.5ul(changeable)
Incubate at 16-18℃,1hr or longer
(Ligation kit from Takara.,Ltd)
