  1. Construct a flow chamber as shown in the video.  Make sure that the parafilm seal is tight and use washed coverslips.
  2. Incubate actin-binding agent in the chamber for 5-10'.
  3. Block non-specific binding sites on the glass coverslip with a blocking protein.
  4. Polymerize actin inside the chamber by flowing in G-actin in polymerizing buffer.
  5. Washout unpolymerized actin by flowing in excess buffer.

Subscription Required. Please recommend JoVE to your librarian.

  1. What is the second pair of shorter parafilm strips for? Why do you polymerize in the chamber and how? G-actin in polymerization buffer. Is't that F-actin? What is the actin binding agent and blocking protein and their buffers and their concentrations?
