Protecting RNA integrity in tissues rich in RNases
Archiving tissues for future microdissection
Collecting samples at locations (e.g., hospitals, field sites, the space shuttle) where immediate RNA isolation is not possible
Shipping samples on wet ice or even at room temperature if shipped overnight
RNA Guardian Solution is an aqueous tissue storage reagent that rapidly permeates most tissues to stabilize and protect RNA in fresh specimens. It eliminates the need to immediately process or freeze samples; the specimen can simply be submerged in RNA Guardian Solution and stored for analysis at a later date. Samples in RNA Guardian Solution can be stored for extended periods under conditions where RNA degradation would normally take place rapidly. Tissues can be stored indefinitely in RNA Guardian Solution at -20°C or below.
