Molecular biology

A technique to separate proteins by their isoelectric points. Proteins are electrophoresed through a gel that has imposed upon it a pH gradient stabilized by the inclusion of polyampholytes, which ...

halt

Biology; Biochemistry

The cessation of transcription due to the absence of a nucleoside triphosphate substrate (in describing the action of RNA polymerase). This is contrasted with arrest, the cessation of transcription ...

hypoacetylaspartia

Biology; Biochemistry

Hypoacetylaspartia is due to a deficiency of the enzyme N-acetyltransferase (NAT). NAT catalyzes the formation of N-acetylaspartate (NAA) from aspartate and acetyl-CoA. NAA is a brain-specific ...

enhancing screen

Biology; Biochemistry

A device to enhance the sensitivity of autoradiography; the surface that is to be visualized is sandwiched between a photographic film and the screen, which is a film impregnated with a phosphor that ...

cis

Biology; Biochemistry

In stereochemistry, descriptive of a substituent on the same side of a structure that prevents equalization of positions by restricted rotation, e.g. an olefinic bond, a ring or a peptide bond; ...

Alu sequence

Biology; Biochemistry

A small interespersed repeat element (SINE); a repetitive sequence in human DNA found in some introns, and characterized by Alu restriction sites; the locus of some homologous recombinations. ...

enzyme-linked immunosorbent assay (ELISA)

Biology; Biochemistry

A technique that combines the specificity of an immunoglobulin with the detectability of an enzyme-generated chromophoric product to quantify a macromolecule. The enzyme is covalently attached to the ...
