RNA isolation directly from whole blood
The RiboPure-Blood Kit is for the isolation of high-quality RNA directly from whole blood. The kit combines two methods of RNA purification to efficiently remove blood components (protein, heme, genomic DNA, and RNases) that can compromise downstream procedures. The kit includes sufficient reagents for 40 RNA purifications from whole blood samples ranging from 0.3–0.5mL each.
Applications The RiboPure-Blood Kit produces high yields of pure RNA directly from whole blood, eliminating the need to isolate WBCs prior to RNA purification. RNA recovered using the RiboPure-Blood Kit can be used in the most challenging applications, including real-time RT-PCR and array analysis. Average yields of RNA are between 2–4µg/0.5mL of whole blood (variation is due to differences in WBC numbers between samples).
Stabilize RNA in whole blood When collecting blood samples for RNA analysis, storage of the samples prior to RNA isolation is often required. The RiboPure-Blood Kit contains RNA
later Solution for the stabilization of RNA in whole blood. It also “freezes” the gene expression profile of the cells. Treated samples can be safely stored at ambient temperature for extended periods of time (up to three days or more). Blood samples stored in RNA
later Solution yield RNA of comparable quality to blood samples processed directly.
Simple procedure yields highly pure RNA The RiboPure-Blood procedure consists of three steps: 1) addition of Lysis Solution directly to RNA
later-treated or fresh whole blood, 2) initial RNA purification by phenol/chloroform extraction, and 3) final RNA purification on a glass fiber filter. An additional DNase treatment can then be performed with the DNA-
free Reagents included in the kit. The entire procedure, including DNase treatment, can be completed in less than 1 hour.

Accessory products The RNA can subsequently be enriched for white blood cell (WBC) mRNA using our GLOBINclear™ Kits to selectively remove globin transcripts. The Mouse RiboPure-Blood RNA Isolation Kit (Cat. No. AM0951) is also available for the recovery of total RNA—and optionally microRNA—directly from mouse or rat blood. Mouse RiboPure-Blood includes sample tubes preloaded with RNA
later™ Solution to prevent RNA degradation and preserve RNA profiles. Not high-throughput compatible (Manual) DNA and RNA Purification and Analysis, RNA Extraction, Total RNA Isolation, Total RNA from Blood
