Introduction
The Total RNA Mini Kit (Tissue) was designed specifically for purifying total RNA from a variety of animal and paraffin-embedded tissue. Tissue samples can be efficiently homogenized in a microcentrifuge tube using the provided micropestle. Detergents and chaotropic salt are used to lyse cells and inactivate RNase and optional DNase treatments can be followed to remove unwanted DNA residue. RNA in the chaotropic salt is bound by the glass fiber matrix of the spin column (1). Once any contaminants have been removed, using the Wash Buffer (containing ethanol), the purified total RNA is eluted by RNase-Free Water, and is ready for use in RT-PCR, Northern Blotting, Primer Extension and cDNA Library Construction. Phenol extraction or alcohol precipitation is not required.

Quality Control 
The quality of the Total RNA Mini Kit (Tissue) is tested on a lot-to-lot basis by isolating total RNA from a 25 mg animal tissue sample. The purified RNA is quantified with a spectrophotometer and checked by electrophoresis.

*Add absolute ethanol (see the bottle label for volume) to the Wash Buffer prior to initial use.

Caution 
RB Buffer contains chaotropic salt which is a harmful irritant. During operation, always wear a lab coat, disposable gloves, protective goggles, and (anti-fog) procedure mask.
