I used universal sequencing primers i.e, CMV-F and BGH-R. Could someone suggest what is the issue? Is it the primers, if not then what could it be?Sequencing reaction is not at all working. Plasmid performs good upon quality check.
can you post an .ABI file of the failed sequencing please.They contain a lot of useful information. Are all of your sequences failing and have you checked that the primer sequences exist in your vector. Are you sure that your sequence is in the vector on the samples that you are sequencing
