| biotinylation | A technique whereby biotinyl groups are incorporated into molecules, either that catalyzed by holocarboxylase synthetase during enzyme biosynthesis or that undertaken in vitro to visualise specific substrates by incubating them with biotin-labelled probes and avidin or streptavidin that has been linked to any of a variety of substances amenable to biochemical assay. Biotinylated dutp is an alternative method to radioactive DNA labelling in vitro. (12 Dec 1998) |

| biotechnology |
1. Using living organisms or their products to make or modify a substance. Techniques include recombinant DNA (see Genetic Engineering) and hybridoma technology. 2. Industrial application of biological research, particularly in fields such as recombinant DNA or gene splicing, which produces synthetic hormones or enzymes by combining genetic material from different species.
