Plasma membrane and protrusion stiffness and viscosity.

<p>Plasma membrane cholesterol concentration in control cells is 7.54 pmol/µg protein. Lat-A represents treatment of the cells with Latrunculin-A in order to disrupt F-actin polymerization.</p>¶<p>Membrane tether effective viscosity was not determined at 5.68 pmol/µg protein cholesterol concentration, but its value under cholesterol depleted conditions at 6.6±0.3 pmol/µg protein was ≈2.1±0.4 pN.s/µm <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057147#pone.0057147-Khatibzadeh1" target="_blank">[13]</a>.</p>
