BD BBL Agarose, 500g

Agarose is a complex galactose polysaccharide of near neutral charge. It is specially prepared and is intended mainly for use in gel electrophoresis.

Agarose is the low sulfate, neutral gelling fraction of agar. During the fractionation of agar, the agarose-portion is separated from the highly charged polysaccharides (high sulfate, nongelling portion), purified and dried. Because of its method of preparation, Agarose is considerably purer than the special kinds of agar, with respect to ionic groups, rendering it more valuable for gel electrophoresis. In addition to high chemical purity, Agarose must exhibit certain physical properties; e.g., high gel strength and high gel clarity. The suggested concentration for use is 0.5-1.2%.
