Abstract

AbstractContinuous gradient gels in capillaries with acrylamide concentrations ranging from 2–20 % or alternatively from 2–40 % are equally suited for the fractionation of complex mixtures of macromolecules in aqueous solutions within a range of molecular weights from 103‐106. A time‐saving method for the simultaneous preparation of up to 48 identical linear micro‐gradient polyacrylamide gels is described. With this method it was possible to compare the patterns of aqueous extracts and to determine tissue‐specific bands of the moss Funaria hygrometrica L. Sibth. in the low molecular weight range for the first time.
