Mouse RiboPure™-Blood RNA Isolation Kit (Invitrogen™)

For the purification of extremely high-quality total RNA (and optionally, microRNA) from mouse or rat blood in about 35 minutes. The Ambion™ kit includes sufficient reagents for 25 RNA purifications from whole blood samples ranging from 0.1–0.5 each.

• Includes RNAlater™, predispensed in 2 mL tubes, for RNA stabilization
• Resulting RNA is suitable for stringent downstream applications such as array analysis and qRT-PCR

Due to interference from the enzymatic inhibitors and anticoagulants present in blood samples, RNA purification from whole blood requires a stringent isolation method that yields high-quality RNA depleted of inhibiting agents and contaminants. The kit includes microfuge tubes preloaded with RNAlater™ Tissue Collection:RNA Stabilization Solution, an aqueous, nontoxic storage reagent that prevents RNA degradation and preserves RNA profiles within samples. Stabilized samples can be stored at room temperature for up to 3 days or at –20°C for long-term storage. The related Figures show the performance of RNA isolated with the Mouse RiboPure™-Blood Kit in real-time RT-PCR. The kit includes an alternative protocol for isolating total RNA that contains microRNA. Typically, 30–55 μg of total RNA (containing microRNA) is obtained from 0.5 mL mouse blood. Yields from rat blood are considerably more variable, generally 18–40 μg from 0.5 mL blood.
