Primer Dimer problems in real-time PCR - (Nov/22/2005 )

Pages: Previous 1 2 

Is there any way that the % agarose or voltage or run time is making is hard to discern between primer dimers (which can be 20~80bp, or bigger) and a 100bp PCR rpoduct? Im sure you've addressed this, but just in case...

Also, compare the melt temps of the pos control to the NTC

Good luck
