Magnetic beads can be used as solid support phase in DNA extraction and purification protocols by a simple bind/wash/elute principle. The products in this category are intended for own development of protocols and are suitable for various sample sources and buffer systems. MagSi-beads for genomic applications are available with a range of physical properties and a silica or carboxyl modified surface. MagSi-DNA Trial kit for molecular biology A complete set of the 8 types of MagSi beads for genomic applications, offered in a single kit for trial purposes in development of new assays. Intended for nucleic acid isolation from various sources (blood, cells, bacteria etc.) for manual and automated work-flow. The kit contains 2 ml each of MagSi-DNA, MagSi-DNA COOH, MagSi-DNA allround, MagSi-DNA allround COOH, MagSi-DNA 600, MagSi-DNA 600 COOH, MagSi-DNA 3.0 and MagSi-DNA 3.0 COOH.
