The RNA Clean & Concentrator-100 kit are RNA clean up kits that provide a simple and reliable method for the rapid preparation of high-quality, RT-PCR-ready RNA. This simple procedure is based on the use of a unique single-buffer system and Zymo-Spin column technology that allows for selective recovery of total RNA (> 17 nt), large RNAs (> 200 nt), and/or small RNAs (17-200 nt). The procedure is easy: Add binding buffer and ethanol to your sample, then bind, wash and elute ultra pure RNA. The RNA can be eluted from the Zymo-Spin V-E Column in as little as ≥ 100 µl of RNase-free water. The highly-concentrated, purified RNA is suitable for all subsequent analyses and molecular manipulations.
