Binding performance test using a membrane
We used Immobilon-P transfer membrane to evaluate the performance of streptavidin-biotin binding of bacteria onto a surface. Before cutting apart the membrane into small pieces, pre-activation should be applied to it first (see protocols membrane biotinylation). After the pre-activation, the membrane was first sheared into strings manually by using scissors, with the width and thickness being approximately 100μm. We then used Leica-crytomicrotome to cut the “threads” into even smaller fragments, with the length of which being 60μm. A binding performance testing device demension was aproximately 100μm×60μm×100μm. Since the surface of membrane had already been activated, the polar-expression bacteria could bind onto such biotin-coated motors.
