Good day! Recently I started working on real time PCR on Bio-rad CFX96. After reactions, I have some problems with result interpretation. As I understand it - contamination. Is it correct? And maybe some other information can be extracted from these graphs? Green bar - experimental sample, blue - GAPDH standard, red - controls - high red - NTC (nothing), low red - negative control of nucleid acid extraction. I add file in .prcd and some screenshots.
