Gravity Blotter Blotter Area 14 x 29 cm (GB-14X29.01)

The SERVA Gravity Blotter has been developed by SERVA to blot film-based IEF and SDS PAGE gels at high efficiency. When performing horizontal gel electrophoresis the gel layer has to be stabilized by a backing, either by glass or plastic. This backing has to be removed before transferring the separated proteins onto a membrane by tank or semy-dry blotting. During this laborious process, the gel could get damaged. The use of the Gravity Blotter renders separating gel and film backing unneccessary. The results are comparable to tank or semi-dry transfer methods. The unit consists of a base plate with a transfer area of 14 x 29 cm. The pressure is provided by aluminum plates that are placed on top of the blotting stack. Transfer time is 4 h or overnight.
