As i understood these are the steps for PMR calculation- Step 1. Divide mean values/ copy (gene) by mean values/ copy (alu) for the test sample Step 2. Then do the same for M.sss1 treated DNA Finally divide step 1 by step 2 and multiply with 100. The mean values / copy for alu will be Calculated via standard curve but how I can calculate the mean value/ copy for the test gene? Should I keep the standard curve for each gene using m.sss1 treated DNA?can i do relative quantification instead of standard curve method?
