TissueLyser LT

The TissueLyser LT provides effective disruption of human, animal, and plant tissues, bacteria, and yeast, allowing reproducible yields of DNA, RNA, and protein in subsequent purification procedures (see figure "Effective tissue disruption"). Even difficult-to-lyse tissues such as heart and brain can be processed by the TissueLyser LT. DNA, RNA, and protein remain intact after disruption (see figures "Pure RNA with high RIN values", "Intact protein suitable for all types of analysis", "High-quality DNA from animal tissues", "High-quality DNA from plant tissues", and "Intact RNA from plant tissues"), enabling reliable analysis in downstream applications.

Disruption with the TissueLyser LT is comparable to that achieved with the well-established TissueLyser II (see figures "Effective tissue disruption", "Intact protein suitable for all types of analysis", "High-quality DNA from animal tissues", and "High-quality DNA from plant tissues").

Genotyping, gene expression, and proteomics applications demand effective disruption of biological samples to ensure high yields of DNA, RNA, and protein. The TissueLyser LT 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 LT 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 LT is fully compatible with QIAGEN manual sample preparation kits (see table "QIAGEN purification kits compatible with QIAGEN disruption systems"), and also complements QIAGEN"s range of automated solutions for medium-throughput sample preparation and analysis (see table "QIAGEN medium-throughput automation"). These include the QIAcube, which automates sample purification using QIAGEN spin-column kits, and the QIAxcel, which automates multicapillary gel electrophoresis of DNA and RNA.

The TissueLyser LT works in combination with the TissueLyser LT Adapter. Up to twelve 2 ml tubes, each containing a sample and a bead, are loaded into the adapter, which is securely fastened to the piston of the TissueLyser LT. The piston moves up and down rapidly, leading to simultaneous disruption and homogenization of the samples due to the beating and grinding action of the beads.

The TissueLyser LT has a small footprint of 15 cm x 27 cm, allowing installation in any laboratory. As each sample is safely sealed within its own tube, the TissueLyser LT is able to disrupt multiple samples without any risk of cross-contamination. If disrupting fresh or frozen samples, the TissueLyser LT Adapter can be precooled on dry ice to prevent degradation of nucleic acids and proteins (see figures "High-quality DNA from plant tissues" and "Intact RNA from plant tissues"). Tissues stored in Allprotect Tissue Reagent (to stabilize DNA, RNA, and protein) or in RNAprotect TissueReagent (to stabilize RNA) require no precooling of the adapter.

The ability to process up to 12 samples per run makes the TissueLyser LT the ideal front-end solution to access biological information for genomics, transcriptomics, and proteomics applications. The TissueLyser LT enables fast and uniform disruption of animal and human tissues, plant tissues, bacteria, and yeast in the TissueLyser LT Adapter, which holds up to twelve 2 ml sample tubes. Sample purification can be performed manually, or can be automated using the QIAcube, QIAsymphony SP, QIAxtractor, EZ1 Advanced, EZ1 Advanced XL, or BioRobot, or BioSprint instruments.
