Plant genomic DNA isolation kitsSuccessful plant DNA extraction that’s easy on youPlant tissue is difficult to work with due to the highlevels of polysaccharides and polyphenols present.Compounding this complexity with tedious, inefficientmethods only prolongs the process of isolation. Cetyltrimethyl ammonium bromide (CTAB) methods requireexcessive time and handling, limiting your throughput.Some silica membrane and magnetic bead–basedprotocols don’t remove inhibitors inherent in plant samplesthat can carry over into the final product and interfere withdownstream applications.18This leads to frequent sample processing failure, requiringyou to repeat the purification.Our innovative products are specifically designed for easy,high-yield, and high-purity DNA purification from plantsamples. Inhibitors are removed for reliable downstreamresults. Make your DNA isolation from plant sampleseasier on you and on your samples, while achieving highyield, high-purity results with Applied Biosystems andInvitrogen plant molecular biology reagents.

Choose from three distinct systems to meet yourapplication and throughput needs Optimized kits streamline the purification workflow for awide variety of sample types Thermo Scientific BindIt Software enables you tocreate customized protocols for additional flexibility Specially designed consumables allow efficientsample processing22Magnetic separation technologyKingFisher systems use permanent magnetic rodsand disposable tip combs to collect, transfer, and mixmagnetic particles:1. When the magnetic rod—sheathed inside the tip comb—is lowered into the solution, magnetic beads collect at thebottom of the tip comb.2. The tip comb is then positioned in a different row or plate,and the beads are released by moving the magnetic rodsout of the tip comb.3. The tip comb facilitates the mixing of reagents with thebeads as the magnetic head moves up and down.
