Mass spectrographic immunoassay (MSIA)

Biology; Biochemistry

A technique for characterization of antigens, especially when more than one may bind to an antibody. After isolation of an antigen from a solution by using an immobilised antibody, the adsorbed ...

Half-chair conformation

Biology; Biochemistry

The conformation of a pyranose ring that has been strained to place four adjacent atoms in one plane, e.g. the postulated transition state of the N-acetylglucosamine residue during lysozyme ...

Multienzyme complex

Biology; Biochemistry

An aggregate of enzymes of specific composition and geometry that act in sequence on a substrate and that, although separable in vitro, fit and function together for efficiency, e.g. pyruvate ...

TATA box

Biology; Biochemistry

A consensus sequence of eukaryotic DNA, named for its sequence on the coding strand, that aligns RNA polymerase II with the start site, about 25 bp downstream from it; from it; also known as a ...

The reversible formation of a bond between two carbons, one of a carbonyl group and the other adjacent to a second carbonyl group; by extension, a condensation of compounds that share that kind of ...

Rocket electrophoresis

Biology; Biochemistry

A technique for identification and quantification of a material by electrophoresis into a slab of agarose gel that contains an antibody. The height of the leading edge of the area of precipitation is ...

Metabolon

Biology; Biochemistry

A proposed multienzyme complex that is responsible for metabolite channelling, so as to eliminate or minimise loss of efficiency due to the otherwise necessary diffusion of substrates to and of ...
