The Just-a-Plate™ 96 FFPE
Total RNA/MicroRNA Isolation Kit is designed and optimized for easy, fast and
high-throughput isolation of high-quality total RNA and microRNA from FFPE
tissues. No silica membrane, filter plate, or magnetic beads are needed and no chemical
de-paraffin steps are required in the process.
Based on
charm biotech developed Solid
Surface Reversible Binding (SSRB) technology (patent pending), Just-a-plate system employs the 96-well plate surface
coated with proprietary turbo-binders as selective nucleic acid capturers to
efficiently extract RNA and microRNA from FFPE sample tissues. RNA molecules
can specifically interact with the turbo binder in the extraction buffer, while
proteins and other contaminants are not bound and remain in the solution. After washing the plate with washing
buffer to remove unbound material, the purified total RNA and microRNA can be
easily eluted in 10 mM Tris Elution Buffer or water. The novel sample buffers
and process in this kit can also efficiently remove nucleic acid chemical
modifications introduced by formalin fixation step in tissues embedding
process. The modification-removed RNA molecules are better substrates being ready
for use in downstream applications, such as reverse transcription, microRNA
detection, quantitative RT-PCR (qRT-PCR) and other gene expression analysis. Since no silica membrane and beads have been used in the
plate, there are no dead spaces and sample trapping problems related with
membrane or bead-based column or plate methods. These features not only allow
fast buffer washing and easy sample elution, but also provide the maximum
sample recovery, which is extremely important when the sample amount is limit
and there is no room for any sample loss.
