I am studying vesicular transfer in the cell. As the vesicle move inside the cell it must experience vuscous drag. Can someone suggest what would be a rough estimate of the viscous drag a vesicle will experience while traveling.
Since cytoplasm is composed mainly of water, the dynamic viscosity of water can be taken for consideration which is, 8.90 × 10−4 Pa. s or 8.90 × 10−3 dyn. s/cm2 or 0.890 cP at about 25 °C.
With presence of multiple organelles and proteins wouldn't the effective viscosity be a bit higher? Fo movement of a 3 um size bed?
Dear Kapish Gupta,
You may consider the dynamic viscosity at the room temperature or at 37 °C depending on the type of your study. The following paper presents a size-dependent study of the dynamic viscosity of complex liquids and cytoplasm:
