Pcr Amplification Graph. This tutorial will discuss the basics of how to interpret an amplification plot of real time pcr introduction real time pcr http youtu be eagh1ekfvc0. The initial pcr cycles 1 endash 19 above produce low fluorescent signals that cannot be detected by the ccd camera.
The initial pcr cycles 1 endash 19 above produce low fluorescent signals that cannot be detected by the ccd camera. A pcr amplification curve which looks like figure 1 is generally a sign of a healthy good pcr reaction. Abnormal amplification curves your amplification curves have a sigmoidal shape amplification occurs later than expected amplification of the no template control ntc no amplification poor pcr efficiency.

Conventional diagnostic procedures are based on the ability to grow organisms in culture or to detect their presence in patients by using antibodies. A normal amplification curve obtained using a dilution series of a sample. As a direct measure of that we could actually go in and measure the slope of our curve during the early pre inflection point part of the second curve phase. Few of us can successfully imagine a trillion of anything so it s no surprise that the general public has trouble understanding how much a covid pcr test amplifies the detected virus to determine whether a test is positive.
