WebDIALYSIS Dialysis is an old established procedure for reducing the salt concentration in samples. It requires filling a dialysis bag (membrane casing of defined porosity), tying the bag off, and placing the bag in a bath of water or buffer. Through diffusion, the concentration of salt in the bag will equilibrate, with that in the bath. Webtechnology of choice for desalting or buffer exchange, avoiding lengthy dialysis steps. While proteins are retained by an appropriate ultrafiltration membrane, salts can pass freely through, independent of protein concentra-tion or membrane MWCO. In consequence, the composition of the buffer in the flow-through and retentate is unchanged after
