MP Biomedicals Lysing Matrix A 4.5 ml Pack of 100 Tubes

MP Biomedicals 6970100 Lysing Matrix A – 4.5 mL TallPrep Tubes, Garnet & Ceramic Sphere

The MP Biomedicals 6970100 (116970100) Lysing Matrix A is an aggressive, high-performance sample preparation consumable engineered for the rapid homogenization of tough, hard, or highly fibrous biological samples. Packaged in 4.5 mL "TallPrep" tubes, this matrix is perfectly sized for medium-volume tissues and accommodates larger lysis buffer volumes without stalling. Each tube is pre-filled with a highly abrasive garnet matrix and a single, heavy-duty 1/4-inch ceramic (zirconium oxide) sphere. This unique combination delivers a dual-action lysis mechanism: the heavy ceramic sphere provides immense concussive impaction to crack open rigid structures like bone or seeds, while the sharp garnet shards simultaneously shear tough fibrous tissues and cell walls. Designed to endure the extreme multidirectional velocity of high-speed bead beaters, Matrix A guarantees thorough disruption for maximum nucleic acid and protein recovery.

Technical Performance and Design

• Dual-Action Lysis: The combination of blunt-force impaction (from the 1/4" ceramic sphere) and aggressive mechanical shearing (from the sharp-edged garnet sand) easily obliterates samples that cause standard uniform beads to fail.

• 4.5 mL TallPrep Format: Bridges the gap between micro and bulk processing, providing the necessary headspace for the heavy ceramic sphere to gain momentum and effectively crush samples up to 600 mg.

• Impact-Resistant Construction: The heavy-duty plastic tubes and secure screw caps are specifically engineered to endure the massive kinetic energy generated by the large ceramic sphere without cracking, leaking, or shedding plastic into the sample.

• Certified Purity: Pre-filled and packaged under strict cleanroom conditions, ensuring the matrix is completely free of DNase, RNase, proteases, and exogenous nucleic acids prior to use.

Key Benefits & Applications

• Tough Tissue Breakdown: The premier choice for forensics, agriculture, and oncology researchers working with dense, calcified, or highly fibrous matrices that resist chemical lysis or traditional sonication.

• Aerosol Containment: The single-use, closed-tube design completely eliminates the hazardous aerosolization and cross-contamination risks associated with open-air rotor-stator homogenizers.

• Rapid Processing Times: Quickly reduces complex tissue networks to a uniform homogenate, minimizing the time samples are exposed to endogenous nucleases and heat.

• Instrument Compatibility: Designed perfectly for the MP Biomedicals FastPrep-24 system when equipped with the TallPrep adapter, as well as other high-power bead mills that accept 4.5 mL or 5 mL tubes.
