After 2 weeks 25 ° C, RNA generally appears slightly degraded (-most of the time acceptable for Northern analysis, but of sufficient quality for protection against nucleases or RT-PCR analysis).
Baada ya 2 wiki 25 ° C, RNA kwa ujumla inaonekana kidogo duni (zaidi kushiriki wakati kukubalika kwa ajili ya uchambuzi Kaskazini, lakini ya ubora wa kutosha na kulinda dhidi ya nucleases au RT-PCR uchambuzi).
