Dear Netters
I hope you all be fine and happy Y2OK.
Please kindly advise me on the following problem if you can think of any
idea:
- When I am running the SDS-PAGE to get the gel for protein separation I can
reach the Voltage even more than 200 but when I want to transfer the protein
to the membrane I can hardly go for more than 10 Volts with the same power
supply, so naturally to have a good transfer I should leave it overnight
while it can be done in one hour with voltage of 100 V. What could be the
reason? Could it be the transfer buffer (I think I should dilute that
more)? If so
please provide me with a suitable transfer buffer ingredients (in terms of
the chemicals and the amounts and the pH).
- What solution I should use to have the sensitivity of 100 ng/ml detection
(DAB & urea peroxidase or immidazol & nickel, or ...., please provide me
with the amounts as well or pH if needed)?
Thanks in advance.
