What is the gentleMACS Dissociator?
It is an automated device used for mechanical tissue dissociation to produce viable cell suspensions.
How do I prepare the buffer for dissociation?
Mix one part BSA stock solution with 20 parts AutoMax fencing solution containing EDTA.
What is the maximum volume of buffer I can use?
Do not exceed a total volume of 10 milliliters for the buffer.
How do I ensure sterility during the process?
Use the septum sealed opening of the C tube cap to pipette while maintaining sterility.
What is the significance of using Max Pres separation filters?
They help remove cell clumps, promoting successful separation and analysis of viable cells.
How can I confirm the viability of the cells?
Viability can be assessed using flow cytometry, staining dead cells with Propidium iodide.
