Magnetic separation dna principles

Nov 26, 2004 The basic principles of magnetic separations can be used in the course of protein or peptide determination using various types of solid phase immunoassays. Usually immunomagnetic particles directly capture the target analyte, or magnetic particles with immobilised streptavidin are used to capture the complex of biotinylated primary antibody and

    After magnetic separation, the magnetic beads are washed to remove contaminants and salts using Wash Buffers 1 and 2 and 80% ethanol. Residual ethanol from the previous wash step is removed by air-drying. Finally, highly pure DNA/RNA is eluted with low-salt Elution Buffer or water. Purified DNA/RNA can directly be used for downstream applications
