Abstract
The present invention provides an improved method for the preparation of ribonucleic acid (RNA) samples. This method utilizes heat and guanidinium thiocyanate treatment of samples followed by alcohol precipitation and centrifugation to prepare RNA samples with a high degree of sensitivity, reliability, and ease of use. Importantly, the prevent invention provides a method in which RNA samples may be prepared so as to conserve RNA preservation and precipitation reagents and time. The samples so prepared are readily amplifiable and may be used for other purposes as well.
