Tissue Homogenizers

Introduction

SB-SWE-FP is a newly upgraded low-temperature homogenizer, which can reach a temperature as low as -50℃ in the chamber and also equipped with a freezing table.Adopt high-speed reciprocating motion of the vertical shaking system, the frozen sample in the grinding tube collides with the grinding bead, and the resulting grinding shear force and impact force completely break down the tissue. Up to 192 samples can be processed simultaneously in one minute, making it a dedicated device that meets the requirements of rapid processing of multi-sample.

Principle

A Chemiluminescence Imaging System operates on the principle of detecting light emitted during a chemical reaction. Chemiluminescence occurs when a chemical reaction produces an excited state intermediate, which then releases energy in the form of light as it returns to a lower energy state. This light emission is captured by the imaging system, typically consisting of a highly sensitive camera (often a cooled CCD or CMOS sensor) and optical components that guide and focus the light onto the detector.

Protocol

Sample Preparation The adapter can be used to grind 96 samples simultaneously in a 96-well plate. The adapter includes a base that can hold a 96- well plate, a top cover, and a locking nut. Take the samples to be ground and place them in the grinding tubes. It is recommended to use no more than 100mg of sample. Add the corresponding extraction solution, ensuring that the total volume of the sample and extraction solution is within half of the overall volume. Add a few appropriately sized grinding beads. To ensure grinding efficiency and quality, for larger volume samples, it is recommended to cut them into smaller pieces using scissors. Unscrew the locking nut and remove the top cover. Place the grinding tubes into the adapter, then attach the top cover and tighten the locking nut in a clockwise direction. (The placement of the tubes should follow the principles of symmetry and balance.) Operation Steps Plug the power cord of the grinder into a grounded 220V power outlet, and turn on the power switch at the back of the grinder. After the startup interface is displayed, wait for about 5 seconds to enter the main operating interface. Once the grinder is turned on, the cooling system starts running. Place the grinding tubes containing the samples, tighten the adapter, and cover the top of the grinder. Set the operating frequency, time, and number of cycles. Click the "Temperature Selection" button to choose the temperature mode and set the desired temperature for the grinding chamber or the cooling platform. Click the start button to begin the grinding process. The instrument will automatically stop once the timer reaches zero. Equipment Maintenance Perform the following routine maintenance  after each use to ensure the reliable operation of the grinder. Make sure to turn off the power and unplug  the power cord before cleaning. If solvents, salt water, acidic or alkaline solutions are spilled on the grinder, immediately wipe them clean with a damp cloth to avoid damaging the instrument. Do not use high-pressure sterilization on any part of the grinder, including the adapter. The components of the adapter should be cleaned after use. Use an appropriate cleaning agent, rinse with distilled water, and then wipe dry with a paper towel. After using an appropriate cleaning agent, wipe the grinder clean with a soft cloth. The following disinfectants and cleaning agents are recommended for cleaning the grinder and adapter: a) Ordinary cleaning agent b) Neutral detergent c) 70% alcohol content

Applications

A tissue homogenizer is an essential tool in biomedical and pharmaceutical research, primarily used for the mechanical disruption of biological samples to facilitate the extraction of proteins, nucleic acids (DNA, RNA), and other small molecules. This process is vital for a wide range of applications, including molecular biology assays, enzymatic studies, and genetic research. For instance, in the extraction of DNA and RNA, the homogenization process breaks down cell membranes and nuclear envelopes, ensuring the release of these nucleic acids for downstream applications such as PCR and sequencing. Studies have shown that effective tissue homogenization is crucial for obtaining high-quality, intact RNA, which is vital for gene expression analyses (Liang et al., 2011). Tissue homogenizers are also indispensable in cell fractionation, a process used to isolate different cellular components. This is particularly useful in studies aiming to understand cellular functions or in the production of biopharmaceuticals, where specific intracellular components need to be recovered intact (Smith et al., 2012). Moreover, tissue homogenizers are widely used in preparing samples for chromatography and spectrometry. Homogenization ensures that samples are uniform and adequately processed, which is essential for accurate analytical results. For example, in metabolomics, tissue homogenization is necessary to release metabolites from cells and tissues for subsequent analysis using techniques such as HPLC or mass spectrometry (Jones & Nguyen, 2021). These devices are also crucial in pharmacological research, where they are used to homogenize tissue samples for drug testing and to extract pharmacologically active compounds from biological tissues. This application is particularly significant in natural product research and drug discovery (Xue et al., 2012).
