A phenomenon in which one fluorophore excites another when there is significant overlap of the emission spectrum of the primary fluorophore with the excitation spectrum of the secondary fluorophore ...

polyclonal antibody

Biology; Biochemistry

A heterogeneous immunoglobulin preparation that contains antibodies directed against one or more determinants on an antigen; the product of daughters of several progenitor cells that have been ...

module

Biology; Biochemistry

In protein chemistry, a building block from which larger proteins are constructed; a recurring folding pattern in proteins, examples of which may have amino acid sequences that are homologous or ...

sodium dodecyl sulphate/polyacrylamide-gel electrophoresis (SDS/PAGE)

Biology; Biochemistry

A technique to dissociate multimeric proteins and to separate all proteins according to their apparent molecular masses. Proteins are treated with sodium dodecyl sulphate (SDS), an anionic detergent, ...

denaturation

Biology; Biochemistry

The destruction of the ordered folding of a protein or nucleic acid that is required for its normal function. Protein denaturation often involves a change from a specific globular or fibrous ...

X-ray crystallography

Biology; Biochemistry

A method for structural analysis of solids that have a repeating unit; dependent upon the ability of electrons to scatter X-rays, and capable of locating in space atoms larger than hydrogen in ...

writhing number (W)

Biology; Biochemistry

A topological property of double-stranded DNA; the number of times one double-stranded segment crosses another in circular DNA, commonly referred to as a supercoil; equal to the linking number minus ...
