Quick recovery:

Better than 95O in minutes.

Most biochemical techniques for elutingseparated samples from electrophoreticgels are frustrating.

Either they're elaborate and time con-

suming or disappointingly low in yield.Extraphor, the new electrophoretic

concentrator from LKB, is the exception.Easy-to-use Extraphor lets you extract upto six samples simultaneously, and yieldsgreater than 95% can be achieved.

Set-up time is just 10 minutes, andwaste is minimal. Extraphor uses a highly

conductive salt solution in a V-shapedchannel to isolate and concentrate thenucleic acid or protein eluted from agarose

or acrylamide gel slices. SDS proteins canbe eluted by adding SDS to the high saltbuffer.

Electrophoretic extraction in a high-salt barrier is such an elegant and efficientmethod, you'll wonder why younever triedit before. To see how it's done, ask your

nearest LKB dealer for an Extraphor datasheet today.
