Abstract:
Biomolecules, especially large polymeric molecules such as enzymes and antibodies, mediate various biological functions, including biochemical reactions and molecular recognition, with high reactivity, efficiency, selectivity and accuracy. Many researchers have investigated methods to take advantage of these characteristics in analytical devices. One way to accomplish this is to immobilize biomolecules in the devices. For example, biomolecules have been immobilized by means of silica sol-gel technology and used for basic research in the food and pharmaceutical industries. Proteins encapsulated by this method retain their structure and biological activity for a prolonged period. This review describes methodologies for immobilization of biomolecules and the applications of sol-gel technology to analytical devices, especially flow-through systems.

SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
