Actin dynamics in a Rac1(Q61L)-expressing PtK1 cell injected with Pak inhibitory fragment PBD/ID(H83L). Fast retrograde flow still occurs in the lamellipodium, but the width of the lamellipodium is re...

Actin dynamics in a Rac1(Q61L)-expressing PtK1 cell. Fast retrograde flow occurs in the lamellipodium and slow retrograde flow in the lamellum. The cell was microinjected with X-rhodamine-conjugated a...

Fluorescently-labeled actin from chicken muscle. Actin is a protein involved in muscle contraction and cell movement. Purified actin can form loose bundles that self-organize into regular patterns...

This video shows stationary epidermal cells with copious retrograde flow of actin. Actin-myosin networks initiate at the cell periphery and flow towards the cell body. Even though actin-nucleation and...

Four general zones of f-actin movement are seen in primary cultures of newt lung epithelial cells microinjected with X-rhodamine actin. At the leading edge and throughout the lamellipodium, f-actin s...

Comparison of actin speckle microscopy with phalloidin staining. Primary cultures of newt lung epithelial cells were microinjected with X-rhodamine actin. Time-lapse FSM was performed on a spinning ...

Chromophore-assisted laser inactivation (CALI) inactivates target proteins by generating reactive photoproducts such as reactive oxygen species (ROS) by intense irradiation of photosensitizer chromoph...
