Mixing and Blending the Cool ideas keep Coming… Grinding and Pulverizing DNA/RNA extractions from normally ungrindable samples including polymers, tough plant and animal tissue, bone, and hair. a b s t r aC ts 1 – Pesticide residue extraction from fruits using QuEChERS method Using the QuEChERS process, studies were done with samples prepared using the standard AOAC method 2007.01. Fruit samples were spiked with 5ppm of 13 common pesticides and then homogenized in the Geno/Grinder® using SPEX SamplePrep Ceramic Grinding Cylinders. These samples were compared to those shaken by hand. For all the pesticides detected, the Geno/Grinder® consistently produced higher recovery rates by an average of over 18%. : : The Freezer/Mill® embrittles samples by: : Immersing the grinding vial in liquid nitrogen; and : Pulverizing the sample with a magnetically driven impactor Tissue Homogenization Cell Lysis : : Low temperatures retained throughout : Room temperature grinding can volatize or degrade the structure and composition of samples unique VertiCal shaking :: handles multiple samples : Freezer/Mill® preserves these samples :: : : Capable of handling multiple samples simultaneously : : Available in two sizes: : Small (6770) for samples from 0.1 – 5g : Large (6870) for samples from 0.1 – 100g 2 – Improved cell lysis and DNA yields from plant tissue A study was performed to discover what Geno/Grinder® processing variables signicantly increased or decreased the yields of genomic DNA in fresh basil. Variables investigated included homogenization time and speed, while buers, grinding media, and tubes were constant. In this experiment, the Geno/Grinder® returned most results higher than 6,557bp meaning that signicant shearing or other degradation did not occur even with longer processing times. from 96-Well Titer Plates up to 50mL Centrifuge Tubes 3 – High-throughput fatty acid extraction from animal tissue samples The research in biotechnology/gene technology often demands the handling of a considerable number of samples. Sample preparation is often the bottleneck in the process of ecient analysis work. Traditional methods based on mechanically disrupting cells using ball or swing mills with an adapter for micro titer plates are no longer suitable for high sample throughput. The use of 96-well micro titer plates and deep well plates in the Geno/Grinder® has been shown to give reproducible homogenization yields for all samples and is well suited for cell disruption of muscle and internal organs such as liver. large Clamp assembly SPEX SamplePrep 15 Liberty Steet Metuchen, NJ 08840-9978 Tel: 732.623.0465 Fax: 732.906.2492 E-mail: sampleprep@spexcsp.com www.spexsampleprep.com To see more detailed information, ask your sales representative for a copy of the Geno/Grinder® application note.
