DNA Production Quality Control Flow Chart
DNA Production Quality Control Primer purity test
Explanation of test results: In the figure, the area of the peak accounts for 100% . So the test is qualified.
Eligibility criteria: The main peak area is 90% or more.
DNA Production Quality Control
MS test result description: Observing the theoretical molecular weight and actual molecular weight, it can be found that the theoretical molecular weight of this primer are 7464.06、5537.86、9357.35、 78🦂20.35 and 8190.07, and the actual molecular weight are 7465.0、5538.7、9358.6、7822.4 and 8187.2. The test is qualified.
Eligibility criteria: The measured molecular weight and the molec🦩ular weight less than 0.1% difference theory
