Successful experiments strongly depend on the quality of the starting material, for example, samples of dissociated tissue. Effective and reproducible preparation of tissue samples can be challenging when using manual methods. For this reason, Miltenyi Biotec has developed the gentleMACS™ Portfolio that enables gentle, yet effective automated tissue dissociation or thorough homogenization with reproducible results.gentleMACS Dissociator Technology combines mechanical tissue dissociation using gentleMACS Dissociators and gentleMACS Tubes with enzymatic digestion based on dedicated Tissue Dissociation Kits. All components of this technology work in unison to yield the maximal amount of viable single cells while preserving cell functions and characteristics, including surface epitopes.
The gentleMACS Dissociator allows for automated dissociation or homogenization of two tissue samples in parallel. More than 30 pre-defined programs are available for processing of the most frequently used tissues, including tumor, neonatal brain, neonatal heart, lung, spleen, and intestine.
The gentleMACS Octo Dissociator enables automated processing of eight samples in parallel or sequentially. Different tissue types can be handled simultaneously and new samples can be added at any time. In addition to utilizing pre-defined programs, users can customize programs to achieve optimal preparation of their specific samples.The gentleMACS Octo Dissociator with Heaters offers all the advantages of the gentleMACS Octo Dissociator. Additionally, the Heaters facilitate enzymatic digestion directly on the instrument for fully automated tissue dissociation.
gentleMACS Tubes have been designed to ensure effective dissociation and homogenization of tissue samples.
The purple-cap C Tube has been developed specifically for the preparation of viable single-cell suspensions used in cell separation, cell culture, and cell analysis experiments.
Tissue homogenizationThe orange-cap M Tube is designed for thorough sample homogenization enabling subsequent molecular and microbiology analysis.
MACS Tissue Dissociation Kits and gentleMACS Dissociators and Tubes are perfectly geared to each other. The combination of gentle mechanical and enzymatic tissue dissociation preserves all cell characteristics and functions for reliable and meaningful downstream analysis. Pre-defined enzyme solutions and lot-to-lot consistency of enzyme activities ensure reproducible and user-independent results.Miltenyi Biotec researchers tested whether the proteases included in the Tumor Dissociation Kits for human and mouse tissue have an effect on the integrity of cell surface proteins. To this end, the presence of more than 200 epitopes was analyzed by flow cytometry after incubation of cells with the enzymes. The vast majority of the cell surface epitopes tested was well preserved during enzymatic treatment.
