Molecular biology

reactive immunization

Biology; Biochemistry

A technique to widen the scope of catalytic reactions effected by abzymes. Reactive compounds are used as antigens; some of the resulting antibodies are directed to the reaction complex with a ...

Descriptive of killer T-cells that recognize and respond to a cell- surface marker on a T-cell that is actively secreting immunoglobulin; contrasted with anti-idiotypic, descriptive of killer T-cells ...

Superoxide dismutase

Biology; Biochemistry

Enzymes that catalyze the dismutation of superoxide to hydrogen peroxide through the use of a redox active metal cofactor such as a copper or a manganese. In mammals there is a cytosolic isoform ...

hydroxylamine and osmium tetroxide (HOT) technique (chemical mismatch detection)

Biology; Biochemistry

A method for detection of single base substitutions in DNA fragments. Heteroduplexes of normal DNA and homologous mutant DNA are generated; the presence of C mismatches allows cleavage with ...

actin

Biology; Biochemistry

A protein present in eukaryotic cells, forming actin filaments, which is a major component of the cell's cytoskeleton, the network of relatively rigid structures within a cell that give it shape. ...

complement system

Biology; Biochemistry

A series of blood proteins that contribute to innate immunity. When triggered by a foreign substance or particle, a cascade of enzymatic activations and reactions results in chemotaxis, activation of ...

fluorescence lifetime

Biology; Biochemistry

The average time that a population of fluorophores spends in the excited state before collapse to the ground state. The lifetime is equal to the reciprocal of the first-order rate constant for the ...
