Comparison of transfer methods in Western blotting | Cytiva
After gel electrophoresis, Western blotting starts with the transfer of proteins from the gel to membrane. Electrotransfer is a common technique for step and takes advantage of the same electromobility principles as gel electrophoresis. Wet and semidry transfer are the two most common electrotransfer methods and provide greater speed and ...Web

Are you ready to transfer your protein? Wet vs. semi-dry transfer
Semi-dry transfer: paper > gel > membrane > paper (all wetted in transfer buffer) Wet transfer: sponge > paper > gel > membrane > paper > sponge . Larger proteins transfer more slowly from gel to membrane, so you may consider extending the transfer time depending on the size of your protein of interest. If you do this, we recommend lowering …Web

Semi-dry systems are also time-efficient as blotting usually finishes within an hour, but a low voltage gets applied overnight in a wet transfer. While semi-dry transfer seems to be the better option as there is a significant reduction in both the volume of transfer buffer and length of transfer time, it has its limitations. [26]Web

In a semi-dry transfer system, the distance between electrodes is determined only by the thickness of the gel-membrane sandwich, and buffering and cooling capacity is limited to the buffer in the filter paper. As a result, the field strength is maximized in semi-dry systems, and the limited buffering and cooling capacity restricts the transfer ...Web

Wet Tank or Semi Dry Transfer: What's best for Western blotting?
Semi-Dry Electroblotting . For semi-dry transfers, the transfer sandwich is placed horizontally between the two plate electrodes in the transfer apparatus. A constant current (0.1 to 0.4 A) or voltage (10 to 24 V) is applied for 10 minutes to one hour. It is possible to get transfer efficiencies of 60% to 80% for proteins between 14 and 116 kDa.Web
