Electrophoresis kinetic friction or not?

[sameeralord]

Hello everyone,

In electrophoresis the least dense one moved less (other factors been the same for every particle). I'm assuming this is due to higher volume and more resistance but, doesn't electrophoresis measure kinetic friction, so the one with lowest density should move further. What kind of resistance does electrophoresis refer to. Thanks

If you are talking about, for example, Western Blots, 'friction' is manifested in terms of viscosity- the process separates substances by charge and size, and the mobility of the charged (mobile) phase depends on viscous effects (which are related back to the charge and size).
