Enzyme-free and gentle Tissue Dissociation
TIGR Tissue Grinder & Dissociator
Modern cell research is increasingly relying on single cell analysis. Whether it is cell analysis in fields like immuno-oncology or drug discovery, gentle single cell dissociation from their matrix is a prerequisite for proper single cell analysis.
The TIGR Tissuel Grinder & Dissociator is a novel semi-automated tool designed for the mechanical dissociation of tissues into single-cell suspensions. By using a purely mechanical process, it avoids the cleavage of membrane proteins, making it ideal for applications that require intact cellular structures. With the ability to process multiple samples simultaneously, the Tissue Grinder & Dissociator ensures high throughput and reproducible results, making it an essential tool for research in cell biology and tissue analysis.

Technology - How it works
The TIGR system enables fast, enzyme-free tissue dissociation compatible with standard cell strainers. It includes a benchtop instrument and a sterile, disposable 50mL grinding tube with a rotor-stator unit featuring counter-rotating teeth.
With adjustable parameters—such as duration, rotation, and speed—researchers can tailor protocols easily through the TIGR software. The entire process takes less than two minutes, far quicker than traditional enzyme-based methods that can take up to an hour.
The grinding unit interlocks with rows of teeth that can be moved against each other. The free rotation of the grinding teeth draws the tissue sample into the free space applying adequate amounts of shearing and milling force to gently isolate single cell from the tissue. The space between the grinding teeth and their fin-shaped geometry allows efficient extraction of viable single cells. The stator is the part that does not move, while the rotor is moved bidirectionally, depending on your customizable programming, allowing for user-defined and -controlled dissociation of the cell tissue.
