WebUsing our example, we’ll take the efficiency of our target gene (97) over 100, and then add one. (97/100) + 1 = 1.97. We will do the same for our reference gene value (95). (95/100) + 1 = 1.95. After running the qPCR, you will get the Ct values for each target and reference gene under control and treatment experiments. did half life alyx make money
