 protein solutions stick to the (glass) capillary, after rinsing and scrubbing. We then treat the capillary with piranha solution. This is annoying and cumbersome and we haven’t yet found a way to avoid/reduce of protein sticking to the surface. But maybe someone
 of you has? <o:p></o:p></span></p>
