Will my PCR product be viable for Sanger Sequencing? I (a dumb undergrad) left my PCR product in the fridge because I was planning on finishing preparing the samples that week to send out but then my coursework got in the way of that project, and I forgot about the samples in the fridge. Long story short, I left my PCR product in the fridge for about a month, and I still need to send those samples out. My question is, should I send them out as-is, or should I re-PCR them using the PCR product as my sample, or worse, take some of the original (limited) DNA from the extraction for a new PCR? I don't want to waste any of my lab's resources either by sending samples that I should just trash out for sequencing, or by doing an unnecessary PCR/ Gel. Thank you in advance.
