Miltenyi cell dissociator

Manufactured by Thermo Fisher Scientific

The Miltenyi cell dissociator is a laboratory device used to mechanically dissociate tissue samples into single-cell suspensions. It utilizes a combination of controlled shear forces and enzymatic treatment to efficiently break down the extracellular matrix and cell-cell adhesions, enabling the isolation of individual cells from a variety of tissue types.

Skin and tumour tissues were cut into small 1 mm2 pieces using a scalpel blade and incubated for 2 hr in digestion buffer containing 25 ug/ml liberase (Roche), 250 ug/ml DNAseI (Roche) and 1x DNAse buffer (1.21 Tris base, 0.5 g MgCl2 and 0.073 g CaCl2) at 37°. Following digestion, tissue was transferred into C-tubes (Miltenyi Biotech) containing RPMI-1640 media (Thermo Fisher) supplemented with 10% heat-inactivated foetal calf serum, 1% penicillin-streptomycin-glutamine (Thermo Fisher) and physically disrupted using a Miltenyi cell dissociator. Spleen and LN tissue was disaggregated mechanically using a rubber policeman. All cell suspensions were filtered and cells were counted using a CASY cell counter (Roche).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
