Western Blotting loading control for large proteins
Posted 30 April 2013 - 04:19 AM
For some time I have had a problem with loading contol for my protein, which is ~250kDa.
Running SDS-page gel, I usually run it so long (5% gel) that anything below 170kDa escape my gel and I can't use any of loading control like GAPDH, Actin, tubulin. I work with HeLa/Hek293 T cells.
I know that I can run a separate gel, run it not so long just to make a loading control (detection of protein ~<100kDa) but I would prefer to have a control on the same gel, it is more reliable.
