loss-of-function

Biology; Biochemistry

Descriptive of a experimental biological model that is designed to be unable to express a particular trait; e.g. a cell line treated with an antisense oligodeoxynucleotide. This contrasts with a ...

high-pressure liquid chromatography (HPLC)

A technique for rapid separation of solutes on a solid support, based on ion-exchange, gel permeation or partition principles; reverse-phase HPLC is when the stationary phase has a non-polar coat; ...

high-performance liquid chromatography (HPLC)

Biology; Biochemistry

Beer-Lambert equation

Biology; Biochemistry

A=ε c ·l; a quantitative definition of the dependence of the absorbance of monochromatic light, A, on the molar absorption coefficient, ε, the concentration of the chromophore, c, and the length ...

opsonin

Biology; Biochemistry

An agent of the blood, especially of the complement system, which can react with by-products of cell damage and with foreign substances and particles, such as bacteria. Opsonization allows leukocytes ...

phosphoinositide cascade

Biology; Biochemistry

A series of events that is initiated extracellularly and leads via activation of phospholipase C to the liberation from membrane phospholipids of inositol 1,4,5-trisphosphate and diacylglycerol, ...

peptidoglycan

Biology; Biochemistry

A polymer of bacterial cell walls that exhibits considerable species variation in structure. It is generally composed of a heterodisaccharide attached to a peptide; the carbohydrate moieties of ...
