Abstract

Lay Description: The cytoskeleton gives a cell its shape and plays a major role in its movement and division. It's also helps organise the content of cells and is the base for intracellular transport. Important components of the cytoskeleton are microtubules, which are hollow cylindrical beams (25 nm in diameter) that assemble from protein building blocks called tubulin. Deficiencies in microtubules are related to many diseases including cancer and Alzheimer. Given their important role, microtubules are heavily investigated in many laboratories. One way to study microtubules is to isolate them from cells and image them using light microscopy. Over the years a number of imaging techniques have been used. These techniques have a number of drawbacks which are addressed by ongoing efforts which this work is a part of. Here, we present a method based on light interference that produce high quality images of microtubules. The technique is cheap and easy to implement making it accessible to a wide base of researchers.
