Endorphin

Biology; Biochemistry

Endogenous morphine-like peptide; one of a class of peptides that are derived from pro-opiomelanocortin by limited proteolysis and have analgaesic properties. The group includes the 31-residue ...

A technique for detection and quantification of radioactivity by capture of the emission from a radiolabel by a primary phosphor which, on emission, excites a secondary phosphor and causes it to emit ...

Endocytosis

Biology; Biochemistry

A process by which extracellular matter is taken up by a cell; the plasma membrane invaginates and encloses the material in newly formed vesicles. In phagocytosis the extracellular material is ...

Fab fragment

Biology; Biochemistry

A product of papain hydrolysis of an immunoglobulin G consisting of the variable region and some of the constant region of a heavy chain and an entire light chain, and containing a single ...

Fc fragment

Biology; Biochemistry

A product of papain hydrolysis of an immunoglobulin G consisting of parts of the constant regions of two heavy chains held together by a disulphide bridge, but excluding antigen-binding regions.

Vibrational optical activity (VOA)

Biology; Biochemistry

A spectroscopic technique for examination of chiral structure, especially of biopolymers, in which the vibrational spectra (infrared and visible), due to bond stretching and bending (as opposed to ...

Vectorette PCR

Biology; Biochemistry

A PCR variation that permits specific amplification of the sequence from a single known internal sequence to the end of the fragment. The source DNA is cleaved by a restriction endonuclease that ...
