Agarose-Acrylamide Gels

At a somewhat more basic level, both agarose and acrylamide gel systems have been used for direct immunofixation. In these gels, samples are electrophoresed and then immunofixed by either using stnps of cellulose acetate soaked in an antibody or the antibody is placed direcdy over the sample area of the gel.

Sialyltransferases can be solubilized from their subcellular site by using detergents, and be purified by affinity chromatography on, for example, CDP-6-aminohexanol-agarose,267 as already described. Solubilization of frog- and rat-liver sialyltransferases by means of Triton X-100 has been described.27 Soluble sialyltransferase occurs in colostrum, and is also present in small quantities in normal blood-serum. From the latter source, the enzyme was purified 300-fold by poly (acrylamide) gel-electrophoresis.2 ... 

Once a DNA molecule has been cleaved into fragments, a particular fragment of known size can be enriched by agarose or acrylamide gel electrophoresis or by HPLC (pp. 92, 90). For a typical mammalian genome, however, cleavage by a restriction endonuclease usually yields too many different DNA fragments to permit isolation of a particular fragment by electrophoresis or...
