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 "Semi-dry" transfer, the gel-membrane sandwich is placed between carbon plate electrodes.

Semi-dry conditions are favorable for transferring proteins in the 30–120 kD range. A third method, the rapid semi-dry transfer has special buffer and material formulations that facilitate the transfer of proteins in as short a time as in 3–10 minutes. The rapid semi-dry method can be used for proteins with a broad range of molecular weights.Web

membranes are submerged under transfer buffer in tanks, and semi-dry transfer, where gels and membranes are sandwiched between buffer-wetted filter papers that are in direct contact with flat-plate electrodes.

Transfer can be done using a wet or semi-dry system. Wet transfer is less prone to failure due to drying of the membrane, and is especially recommended for large proteins. For both kinds of transfer, the membrane is placed next to the gel. The two are sandwiched between absorbent materials, and the sandwich is clamped between solid supports to ...Web

In tank transfer the gel and the membrane, sandwiched between filter paper, are secured in a cassette and submerged in transfer buffer (the ion reservoir).
