Material:
DNA marker: 100bp ladder 8μl
DNA sample: 2μlPCR product + 1μl 6x loading buffer

There is no band appears in the gel electrophoresis.
Conclusion:
Due to the Figure 1 in result, we have to check the temperature of primers annealing and the design of primers to solve the problem. Next, we use gradient PCR to find out the exactly temperature of primer annealing and we add positive control as well.
