Summary

Automatic Translation

Automatic Translation

Denne protokol beskriver dannelsen af understøttede lipiddobbeltlag og tilsætningen af cytoskeletale filamenter og motorproteiner for at studere dynamikken i rekonstituerede, membranbundne cytoskeletale netværk ved hjælp af fluorescensmikroskopi.
