I am working on human mesenchymal stem cells and trying to stimulate cells with high-frequency ultrasound microbeam. I want to observe cell morphology for a couple hours but we don't have a portable incubator on our microscope.
I would suggest 1% (v/v).
I have used different recipe of physiological buffer solutions for live cell imaging previously (such as live cell imaging solution from Thermofisher). Based on Thermofisher's description, " It...
