What Our Scientist Says
Tissue processing doesn't need to be complex and time consuming. STEMprep™ takes the hassle out of sample prep with a sleek, customizable interface and built-in temperature control to keep your samples cool and your workflow smooth. Less time prepping, more time generating data that you trust—that’s the power of STEMprep™.

Overview
³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ simplifies protocol selection and setup with its intuitive touchscreen interface, streamlining workflows and reducing the potential for human error. The system also includes integrated temperature control, ranging from 4 to 37°C, ensuring optimal processing conditions across diverse sample types and applications and eliminating the need for external cooling or heating devices. Whether you opt to use validated º£½ÇÆÆ½â°æ protocols or customize your own, ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ offers the flexibility to adapt to different tissue types and experimental needs.
The system is designed to work seamlessly with ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Sample Tubes and tissue-specific ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Dissociation Kits, enabling efficient sample processing and consistent tissue dissociation across numerous applications.
This modular benchtop platform is scalable to match your growing workflow. It starts with a Primary Unit (which includes the touchscreen interface), and you can increase throughput by adding Secondary Units, each capable of processing up to four additional samples.
System configurations begin with a 4-sample setup that includes one Primary Unit and a Plastic Rack for Centrifuge Tubes. To process more samples, you can add Secondary Units—each one adds space for four more samples. An 8-sample system includes one Primary Unit and one Secondary Unit, while a 12-sample system includes two Secondary Units. All setups come with a Plastic Rack for Centrifuge Tubes. If you need to process more than 12 samples, you can add Expansion Units to increase capacity by four samples at a time.

Figure 1. ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociation Workflow
The ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociator enables efficient processing of a wide range of tissues, including mouse brain, liver, lung, spleen, and tumors. In this workflow, tissue samples are placed into a ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Sample Tube and processed using the ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociator in combination with the appropriate ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociation Kit. Depending on the selected protocol-dissociation or homogenization-the resulting output is either a single-cell suspension or a sample suitable for nucleic acid isolation. ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢-processed cells are compatible with downstream applications such as cell separation, cell culture, flow cytometry, and other assays.

Figure 2. ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Cold Temperature Hold Feature Preserves Mouse Lung and Spleen Cell Viability
Mouse lung and spleen tissues were dissociated using the ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Mouse Lung and Spleen Dissociation Kits, respectively. After the protocol run was completed, the samples were held on the ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociator for up to 24 hours at 4°C, 22°C, and 37°C. Viability of total nucleated (A) lung and (B) spleen cells. Data are presented as mean ± SD (n = 3).

Figure 3. RNA Yields from Tissues Homogenized Using the ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociator Are Comparable to Other Common Homogenization Methods.
Mouse (A) brain, (B) lung, or (C) liver tissues were homogenized using the ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociator or an alternative automated system. RNA was subsequently extracted using the EasySepâ„¢ Total Nucleic Acid Extraction Kit (with DNase I treatment). The yield of RNA per mg of tissue was assessed using the Qubit Flex Instrument and Qubit RNA Broad Range Assay kit. Data are presented as mean ± SD (n = 8).

RNA integrity number (RIN) of RNA extracted from mouse (A) brain, (B) lung, or (C) liver tissues. Tissues were homogenized using the ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Tissue Dissociator or an alternative automated system. RNA was subsequently extracted from the resulting homogenates by EasySepâ„¢ Total Nucleic Acid Extraction Kit (with DNase I treatment). The quality of the extracted RNA was assessed using the 2100 Bioanalyzer Instrument and Agilent RNA 6000 Nano Kit. Data are presented as mean ± SD (n = 8).

Figure 5. ³§°Õ·¡²Ñ±è°ù±ð±èâ„¢ Template Protocol Information
Step 1 (Prime): A brief slow spin during pre-heat.
Steps 2 and 3 (Cut): Steps 2 and 3 are looped with a repeat count of 2. A reverse spin (-40 RPM) is applied to step 3 to ensure free movement of tissue.
Note: Reduce speed for soft tissues. Increase speed or number of loops for hard tissues.
Step 4 (Incubate): Slow spin to agitate tissue during incubation with enzyme cocktail.
Step 5 (Dissociate): High-speed spin to generate single cells.
