Charge transfer

Charge transfer --> charge transfer complex

a complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases.

Synonym: charge transfer system.

Glycine in Western Blot buffers

... faster. With the boundary gone, the protein can migrate by length/charge. I'm no good at pchem so this explanation may be bunk, but I picture ... pushes the protein along. I assume glycine does the same thing in the transfer buffer: push the protein forward onto the membrane through (assuming ...
