I'm trying to understand the relative sedimentation rates of certain cell types and for this it would be helpful to know their density in terms of mass per volume. For example, PBMCs have a density of 1.077g/mL.
However, data seems to be sparse on other cell types. I'm looking for information for MCF-7, MDA MB-231, and dissociated cardiomyocytes.
Right now some of these cells are sinking so fast that they don't even make it into my microfluidics, and I am reluctant to increase the buffer viscosity because this would lower flow velocity and I would prefer for flow velocity to be uniform across my experiments.
