The PCR reagents (and some of our qPCR reagents too) come from an Estonian company, Solis BioDyne. The key innovation from this company is that they are highly-stable at room temperature for up to a month and can also handle freeze/thaw tests exceptionally well.
This means that there is no drama if reagents are left out on the bench and because of this stability, we can courier them to you in a small courier bag saving you money on courier costs.
