Low molecular weight macromolecules ( 10,000 daltons) may diffuse out of gels morereadily. One can allow adequate gel pre-equilibration by changing th

2. Place a pre-soaked sheet of extra thick filter paper onto the platinum anode. Roll a pipetor test tube over the surface of the filter paper (like a

7. Carefully place the cathode onto the stack. Press to engage the latches with the guideposts without disturbing the filter paper stack.8. Place the

4.3 Assembly of the Unit for Acidic TransfersIf an acidic transfer buffer is used, the transfer direction will be from the anode to thecathode.1. Rem

Note: Some pH electrodes will not perform a proper measurement for the pH of Trisbuffers. If the pH of the buffer is not correct, check the electrode

6.2 DNA Blotting(For acrylamide gels with DNA 250 bp to ~1 kb)Electrophoresis Run on a Polyacrylamide Gel1. Prepare the stock electrophoresis 5x TBE

Nitrocellulose membranes have been used extensively for protein binding and detec-tion.7,19-22They can easily be stained for total protein by a dye st

6. Methanol in the transfer buffer is restricting elution of proteins from the gel. Eliminationof methanol results in increased transfer efficiency, b
