What is native buffer?
NativePAGE™ Sample Buffer (4X) is a solution used to solubilize native protein samples prior to use with the NativePAGE™ Gel System.
Can you reuse MOPS running buffer?
Sometimes, if the buffer goes bad, the gel runs crooked. But this can also happen if the buffer level is low. In this case, if you re-add fresh running buffer, the gel starts running properly again. So, the bottom line is: You can safely re-use the running buffer upto three times.
Can you leave gel in running buffer?
Ideally you can keep the gel 15-30 in transfer buffer(Towbin). If you keep for longer there may be chances of disappearing of protein bands since Towbin buffer contain 20% methobol.
How do you store native PAGE gel?
Upon receipt, store the gels at 2ºC to 8ºC. Do not freeze NativePAGE™ Gels. The expiration date is printed on the gel.
Why is it essential to make sure you do not have a leak of buffer from the inner chamber of the gel holder?
When loading an SDS-PAGE gel, why is important to ensure there are no leaks from the inner chamber? What will happen if the buffer level is too low? The electrode assembly will leak when you fill it with buffer. The buffer must be above the ledge created where the wells are loaded, or the gel will not run.
How long can gel sit in buffer?
You can use the gel later within 1-2 days by keeping it in buffer, but better is to use fresh gel each time. The gels can be used even after 1-2 weeks, keeping it in 4oC.
Can you run a gel overnight?
Of course you can run gel overnight, but I suggest checking concentration of stacking gel at first – it is a little bit strange that your protein as well as the marker is migrating so slowly in stacking gel.
How do you adjust the pH of a MOPS buffer?
Bring the pH to 7.0 with NaOH (or if the MOPS sodium salt is used, then use glacial acetic acid to adjust the pH). Do not autoclave. Store in the dark, covered with foil, at room temperature. The solution will turn yellow with time, but this is normal.
