1. Prepare dialysis tubing with an appropriate cut-off molecular weight.
Check for instructions for the tubing type
you use. If not ready to use, depending on the type, you may chose
one of the following method to prepare the tubing:
Microwave in ddH2 for a few minutes. Don't allow
it to boil.
(Warning: some
brand of dialysis tubing can't be boiled or cut-off may change when heated over 37 °C.)
2. Dialysis tubing can be stored at 4 °C in ddH2O/0.1% sodium azide.
3. Rinse with ddH2O thoroughly before use.
4. Cut a tubing of the appropriate size, clip one end with a dialysis tubing clip. Test for
leaks with ddH2O.
5. Remove water, and add samples. Clip the other end.
6. Dialysis in at least 100X volume of the buffer the sample will be exchanged into.
Stir slowly with a magnetic bar. Cool the buffer before hand and dialysis at 4 °C if the sample is temperature
sensitive.
7. Change the buffer every 2-4 hours for at least 3 times.
8. Carefully remove the sample out of the tubing.
