Wet Tank or Semi Dry Transfer: What''s best for Western ...
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.

Western Blot Protocols Original
Transfer Transfer There are two blotting method types, semi-dry and tank blotting. The semi-dry method is more likely to be preferred because the blotting time is shorter. As for the membrane, PVDF membranes tend to be used more frequently because their protein binding strengths exceed those of nitrocellulose membranes.

Semi-Dry vs. Wet Transfer for Western Blot
A semi-dry transfer is suitable for convenience and speed provides high output results. Semi-dry transfer systems are easier to set up, take up less time and require less buffer. A wet transfer, on the other hand, is ideal for routine protein work and most flexible in terms of blotting times, voltage settings and cooling options.

The Basics of Western Blotting
· The wet transfer process is very effective in transferring a broad range of protein sizes but takes hours to overnight. In contrast, a semi-dry transfer only requires enough buffer to saturate the sandwich and typically takes less than an hour. However large proteins typically do not transfer as well using this method.

Increased Transfer Efficiency Using A Discontinuous Buffer ...
Semi-dry transfer has traditionally been a fast but inefficient method for transferring all the protein from a gel. By using a discontinuous buffer system, transfer efficiency can be greatly increased. In protein blotting, the buffer has an important effect on the elution of the proteins from a gel and the retention of the protein to the membrane.
