BN-PAGE of purified membrane associated protein

... time I used buffer containing coomassie brilliant blue (CBB) G250. Later I read that it is not necessary for purified proteins. The CBB of the cathode buffer is supposed to be enough to charge the protein. And in fact I do not see any differences between the the loading buffer containing CBB ...

Re: Running SDS PAGE for the first time!

Hi, welcome :) there are several protocols. I have used one with only one running buffer, but last time I have tried other, where were different cathode and anode buffer ;) Actually cathode buffer can be used in subsequent run as anode buffer (or vice versa?). I think, that 50 ug will be plenty ...

Running SDS PAGE for the first time!

... I am running SDS PAGE shortly and had a few quick questions: Is a running buffer and loading buffer the same thing? If so, are they used as cathode and anode buffers? I have read that cathode and anode buffers are two separate solutions, however some sources suggest that they can be the ...

Polyacrylamide gel running

... and the fast chloride ion (in the gel). If Chloride ions are present in the buffer this effect is diminished. 2)The buffer is electrolysed at cathode and anode (remebmber the bubbles at the electrodes?) which changes the pH of the buffer. So never reuse the buffer in SDS-gel electrophoresis. ...
