pre-cast gels) usually use the buffer substance Bis-tris methane with a pH value between 6.4 and 7.2 both in the stacking gel and in the separating gel. These...

the gel during the electrophoretic run. The gels typically consist of acrylamide, bisacrylamide, the optional denaturant (SDS or urea), and a buffer with...

and physical properties of ACES buffer. ACES had been used to develop buffers for both agarose and polyacrylamide gel electrophoresis. ACES use in isoelectric...

biology, gel extraction or gel isolation is a technique used to isolate a desired fragment of intact DNA from an agarose gel following agarose gel electrophoresis...

thus the gel temperature is much lower than with TBE/TAE buffers, therefore the voltage can be increased to speed up electrophoresis so that a gel run takes...
