Semi dry transfer. In a semidry transfer, the stack consists of gel and membrane placed between two pieces of filter paper, all equilibrated in transfer buffer, and this stack is placed directly between two electrode plates With semidry transfers, transfer times are reduced to about an hour, but may be as short as 5 minutes with rapid semidry transfer protocols. Semidry transfer requires low voltage ( V) and high current Check with the manufacturer of the power supply to determine whether it is appropriate for semidry transfer Transfer performed for too short a time Increase the amount of time for transfer Typical transfer times range from 30 to 60 minutes. Semidry transfer The Invitrogen Power Blotter semidry transfer system is an allinone, integrated transfer system There is no need for an external power supply–the Power Blotter features an integrated power supply capable of delivering high current for rapid transfer.

In a semidry transfer, a sandwich consisting of paper > gel > membrane > paper wetted in transfer buffer is placed directly between positive and negative electrodes (cathode and anode respectively) As for wet transfer, it is important that the membrane is closest to the positive electrode and the gel closest to the negative electrode. Semidry methods require very low amounts of transfer buffer, which lowers the buffering capacity of the system Although Towbin transfer buffer is suitable in most cases, alternate transfer buffers could be considered for optimizing transfer efficiency. Optimizing SemiDry Transfer Transfer buffer Semidry methods require very low amounts of transfer buffer, which lowers the buffering capacity of Gel equilibration Some electrophoresis components, particularly SDS, increase the conductivity of the transfer buffer Electrode contact.

Semidry has been working perfectly for my proteins But I have heard complaints from colleagues next door about one of their proteins that does not transfer at all in semidry, yet transfers very well with conventional transfering system (the sandwich in a tank with ice block) Have you tried with the conventional transfering system?. I transfer 70kDa to 250 kDa from the same gel of SDS PAGE 68% about 10 cm X 8cm using Biorad semi dry apparatus They transfer like blotch!. In a semidry transfer, the gel and membrane are sandwiched between two stacks of filter paper and are in direct contact with plate electrodes (Bjerrum and SchaferNielsen 1986, KyhseAndersen 1984, Tovey and Baldo 1987) The term “semidry” refers to the limited amount of buffer, which is confined to the two stacks of filter paper.

Semidry transfer A “semidry blot” where you sandwich is not completely immersed is not as counterintuitive as may think After all, you will get wet swimming in a pool but to just to get your body wet a small volume of a sponge would suffice In semidry transfer, the buffer is confined to the sandwich placed between the plate electrodes. A semidry transfer is suitable for convenience and speed provides high output results Semidry 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. For a semidry transfer, either shorten the run time, increase the number of filter papers, or reduce the current Filter paper dried out during semidry transfer Make sure filter paper is thoroughly drenched prior to transfer or use additional sheets Be sure the stack is assembled in less than 15 minutes.
