CCP4bb navigationCCP4bb <-- 2007 <-- May 2007 <-- 12 May 2007Subject: Re: Superdex 200 PC columns From: mlamers {- at -} BERKELEY {- dot -} EDU mlamers {- at -} BERKELEY {- dot -} EDU Date: 2007-05-12 In my experience, there is no problem running a SMART column on an AKTA FPLC or Explorer. I have been using the same S75, S200, and Superose6 columns on all three systems depending on which one is available that day. I typically load 50 ul sample, between 10-0.01 mg/ml. The peak width I get is ~150ul, with 70-80% of the original concentration at the height of the peak. On the FPLC/Explorer I replace the standard tubing to shorter and more narrow tubing and bypass the conductivity meter to reduce the amount of dead volume. Finally, for the very low protein concentrations, you're better of using the Explorer, which allows you to measure the absorption at 220-230nm.
