Cells are lysed by incubation in a solution containing chaotropic ions. This lysis buffer inactivates RNases creating appropriate binding conditions favouring adsorption of RNA to the silica membrane. After lysis, homogenisation and reduction of viscosity are achieved by filtration with NucleoSpin™ filter units. Contaminating DNA bound to the membrane is removed by a DNase I solution directly applied to the membrane during preparation. Optimal conditions for DNase are achieved by washing the membrane with a specific desalting buffer before treatment. Salts, metabolites and macromolecular cellular components are removed by simple washing with two different buffers. Total RNA is finally eluted with RNase-free water. The NucleoSpin™ RNA Plant kit features two alternative lysis buffers: in most cases, use of buffer RA1 is recommended for lysis due to its strong denaturing properties. The presence of peculiar metabolites in a variety of plant tissues or fungi may lead to solidification of the lysate, resulting in non-processible slurry. In such cases, the alternative buffer, RAP is the buffer of choice. For thorough homogenisation and reduction of lysate viscosity, NucleoSpin™ filter units are also provided. Kit components: NucleoSpin™ RNA columns with 2mL collecting tubes, 2mL collecting tubes, 1.5mL microcentrifuge tubes, NucleoSpin™ filters, buffers, RNase-free DNase I, DNase I reaction buffer, RNase-free water.
