Real-Time PCR - No plateau! (Oct/04/2004 )

I do not reach plateau in my fluorescence curve. It just keeps on going up for all of my treatment samples. I am using 45 cycles and my primer: beacon pairs are optimal. What is going wrong? I increased my primers to 500nM and my beacons to 250nM conc. The target sequence is expressed in low amounts but I don't think that should be the problem. Should I add another cycle so that I have an denature anneal and extend program? Or do I need to extend my annealing time? Please Help! I am in dire need!


Is your amplification plot scaled correctly? It sounds like you may just need to adjust the scaling on the graph/output.
