Introduction
Transfer of proteins or nucleic acids, fraction-
ated by gel electrophoresis, to an immobilizing
membrane surface increases the sensitivity of
a wide range of detection methods, reduces
time of analysis and makes sequential probing
possible. In particular it has made possible use
of immunological procedures that are not practi-
cal to carry out in a gel. To assay material on a
sheet of membrane with different probes simul-
taneously commonly requires first cutting the
membrane into a number of parallel strips. This
procedure however destroys the correspondence
between different lanes or positions on a gel.
