After isolating T cell gDNA using DNAzol and resuspending in NaOH and HEPES, I quantified DNA recovery using a Qubit and my yield was only about 50%. I think I overdried the pellet and the DNA might not have fully resuspended. I am wondering how to improve resuspension, and if I can incubate the DNA at 37 degrees C (or warmer?) even though I have already frozen it at -20 overnight.
