MagBeads FastRNA Kit for FFPE is based on the purification method of high binding magnetic particles. The sample is lysed and digested. RNA is released into the lysate. After addition of magnetic particles and binding solution, RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing buffer to remove the proteins and impurities, washed with ethanol to remove salts, and finally the RNA was eluted with Elution Buffer.
