TissueLyser II

Genotyping, gene expression, and proteomics applications demand effective disruption of biological samples to ensure high yields of DNA, RNA, and protein. Effortless disruption with the TissueLyser II system is achieved through high-speed shaking with beads, which beat and grind samples. The TissueLyser II system delivers thorough and rapid disruption of samples to fully release biomolecules, and also simultaneously homogenizes samples to facilitate subsequent purification procedures using QIAGEN kits (see table "QIAGEN purification kits compatible with QIAGEN disruption systems").

The TissueLyser II is an integral part of QIAGEN"s complete solution for sample management — from sample collection to purification and analysis of DNA, RNA, and protein. The TissueLyser II complements QIAGEN automation for high-throughput sample preparation and analysis (see table "QIAGEN high-throughput automation"), such as the QIAsymphony SP. This easy-to-use instrument automates purification of DNA, RNA, and protein from 1–96 samples. The TissueLyser II is also compatible with QIAGEN manual sample preparation kits (see table "QIAGEN purification kits compatible with QIAGEN disruption systems").

For RNA applications, stabilization of fresh tissues in RNAprotect TissueReagent prevents RNA degradation during sample handling. For applications requiring purification of DNA, RNA, and protein, these 3 analytes can be immediately stabilized by placing fresh tissues in Allprotect Tissue Reagent.

TissueLyser Adapter Sets allow processing of up to 2 x 96 samples in collection microtubes or up to 2 x 24 samples in 2 ml microcentrifuge tubes. The adapter sets can be precooled at –80°C if disrupting samples without lysis buffer. Tubes remain securely sealed during disruption to prevent cross-contamination, which is especially important for highly sensitive downstream applications, such as real-time RT-PCR or microarray analysis. Depending on the sample type, disruption is carried out using stainless steel, tungsten carbide, or glass beads. TissueLyser Bead Dispensers are available to conveniently deliver single beads into microcentrifuge tubes or to deliver 96 beads in parallel into collection microtubes. The TissueLyser II can also disrupt large samples when used in combination with Grinding Jar Sets.

The ability to process up to 192 samples per run makes the TissueLyser II the ideal front-end solution to access biological information for genomics, transcriptomics, and proteomics applications. For next-generation, high-throughput sequencing technologies, the TissueLyser II is the disruption instrument of choice. A wide range of QIAGEN sample purification kits are compatible with the TissueLyser II, and sample purification can be performed manually or can be automated using the QIAcube, QIAsymphony SP, EZ1 Advanced, or BioRobot or BioSprint workstations.
