Hi guys, I´m new in the forum. Hope you can help me. We´re doing an assay of RT-PCR to get the expression of miRNAs 376c and 141. Today I did a PCR mix (Buffer 5X, MgCl2, dNTPs, Oligos, Taq polimerase and free nuclease free H2O) but I don´t have enough time to run my PCR. How long can I store at - 30°C my PCR mix?
