Biochemistry

A phenomenon in some teleost fish that allows them to generate O 2 gas in their swim bladders in the face of considerable hydrostatic pressure. The haemoglobin structure and the local secretion of ...

Kringle

Biology; Biochemistry

A protein folding motif, as visualised in two dimensions, of loops formed by multiply disulphide-bridged sequences of several circulating proteins, e.g. α 2 -macroglobulin, complement component C3, ...

Spacer arm

Biology; Biochemistry

In affinity chromatography, the chain of carbon and/or other atoms that positions a functional group away from the solid matrix to which it is covalently bound and makes it more available to a ligand ...

Photo-activated repair

Biology; Biochemistry

A mechanism for repair of DNA by reduction of thymine dimers by DNA photolyase; contrasted with dark repair, an ATP-dependent process that involves excision of the dimers, resynthesis of the sequence ...

Zipper interaction

Biology; Biochemistry

The sequence of events by which an immunoglobulin G-coated lymphocyte draws the macrophage plasma membrane around it. Fc receptors on the membrane surface attach the immunoglobulin G markers and ...

Zoo blotting

Biology; Biochemistry

A technique to assess the degree to which a DNA sequence, usually a coding sequence, is conserved in evolution; a test for hybridization of a probe complementary to the sequence in one species ...

Allele-specific PCR (ASPCR)

Biology; Biochemistry

The adaptation of a PCR primer to selectivity for only one variant sequence. The 3'-end of the primer is designed to be complementary to only one allelic sequence, so the appearance of a PCR fragment ...
