Tissue Homogenizers – Sample preparation - Bertin Instruments
Sample preparation is critical to master molecules extraction from biological samples. Bertin Instruments offers efficient and flexible Precellys tissue homogenizers for grinding any samples prior to analysis.
In order to extract the molecules of interest (extraction of RNA, DNA, proteins, metabolites, etc.) from biological samples, sample preparation procedures generally include a tissue homogenization or cell disruption step.
The Precellys® homogenizers from Bertin Instruments use bead-beating technology to homogenize biological samples, such as human, animal or plant tissues, or to lyse micro-organisms. In this way, the biological samples are ground via multi-directional movement (3D bead-beating), the speed of which can reach up to 10,000 rotations per minute, depending on the equipment. Bead-beating is the gold standard method for tissue homogenization compared to standard techniques such as: mortar & pestle, sonication, blender, high pressure homogenizer. It takes just a few dozen seconds to homogenize the samples, which are then ready for an analysis of the molecules of interest (nucleic acids, proteins, metabolites) using different analysis techniques: PCR, sequencing, Western Blot, liquid chromatography, etc. This represents a considerable time saving that simplifies sample preparation protocols.
The high-performance characteristics of the Bertin Instruments homogenizers, together with a wide variety of lysing and grinding kits, offer excellent reproducibility and a great degree of flexibility in a broad range of research areas including microbiology, pharmacology, cancer, forensic medicine, the environment, and even agronomy.
The Precellys® range allows you to prepare samples in full safety and without cross contamination, for both routine applications and R&D projects.
• For infrequent use, the Minilys® homogenizer allows you to prepare up to three samples at the same time. Its flexibility (0.5, 2 and 7 ml tubes) and its small size make it ideal for laboratories needing conventional sample preparation.
• The Precellys® 24 homogenizer can accommodate up to 24 biological samples in 2 ml and 0.5 ml tubes simultaneously. This robust appliance has been designed for daily use in laboratories with biological safety level 3.
• For even greater versatility, the Precellys® Evolution can accommodate up to 96 samples at the same time with six different tube volumes (from 0.3 ml to 15 ml), and meets the safety standards of laboratories with biological safety level 3.Avoid degradation of your heat-sensitive samples during homogenization with Cryolys® Evolution, the sample cooling system compatible with Precellys®

Cancer Research
Hard tissues such as those from tumors can be particularly difficult to homogenize, and animal models are often used in cancer research. Precellys homogenizer is perfectly adapted to applications of this kind.
Agronomy
Agronomy research into GMO analysis, food allergies and plant studies, often require grounded hard samples such as seeds, roots or frozen food, which are particularly hard to grind.
Forensic
Extremely hard samples such as bone, teeth, and hair are common in forensic laboratories. Popular downstream applications include DNA extraction from bone or teeth and drug extraction from hair.
Pharmacology
Pharmaceutical research starts with lead molecule identification from a natural or artificial model. In either case, the DMPK or animal toxicology models analysis requires the homogenization of tissues.
Environment
Soil and environmental analysis often focus on microbiology studies and pollution impact on wildlife. Microorganisms included in a biological matrix are particularly challenging to lyse.
Microbiology
Microorganism studies are critical as they are used for bio-production and health research. They are difficult to lyse due to their thick cell wall, which makes nucleic acid extraction difficult.
