Detection of microRNAs in dried serum blots.


ABSTRACT: We observed the preservation of microRNAs in unrefrigerated dried serum blots. Preservation was not adversely affected by drying or storing at 37, 45, or 60°C instead of room temperature, but it was harmed when blots were dried incompletely before storage. Preservation of microRNAs in serum was not diminished if, instead of being kept frozen at -80°C, it was stored as dried blots at room temperature for 5 months or at 37°C for 4 weeks. Thus, dried blots can be a convenient and safer way to save, transport, and store serum for microRNA assays.
