A procedure for modifying cells by shooting DNA-coated metal (tungsten or gold) particles into them.
Industry:Biotechnology
A procedure for obtaining amniotic fluid from a pregnant mammal for the diagnosis of some diseases in the unborn foetus. Cells are cultured, and metaphase chromosomes are examined for irregularities (e.g., Down syndrome, spina bifida, etc., in humans).
Industry:Biotechnology
A procedure for screening colonies or plaques growing on plates or membranes for the presence of specific DNA sequences by the hybridization of nucleic acid probes to the DNA molecules present in these colonies or plaques.

Industry:Biotechnology
A procedure for the assessment of a substance by measuring its effect in living cells or on organisms. Animals have been used extensively in drug research in bio-assays for the pharmacological activity of drugs. However, bio-assays are now usually developed using bacteria or animal or plant cells, as these are usually much easier to handle than whole animals or plants, are cheaper to make and keep, and avoid the ethical problems associated with testing of animals. Sometimes used to detect minute amounts of substances that influence or are essential to growth.
Industry:Biotechnology
A procedure in which a cloned, labelled segment of DNA is hybridized to DNA restriction fragments on a Southern blot (q.v.).
Industry:Biotechnology
A procedure used to fractionate mRNAs or DNA fragments on the basis of size.
Industry:Biotechnology
A procedure used to separate macro-molecules based on their density (mass per unit volume).
Industry:Biotechnology
A procedure used to separate macromolecules based on their rate of movement through a density gradient.
