Biochemistry
sedimentation-velocity ultracentrifugation
Biology; Biochemistry
A technique that measures the rate of movement of a dissolved polymer under the force exerted upon it in a centrifuge, to assist in evaluation of molecular mass, axial ratio and other hydrodynamic ...
scintillation counting
Biology; Biochemistry
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 ...
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.
fast-atom bombardment mass spectrometry (FAB-MS)
Biology; Biochemistry
A technique for the analysis of protein sequence and structure. A high energy beam of atoms or ions (Cs or Xe) vapourizes, fragments and ionizes a protein solution, the mass spectrum of which gives ...
fast-atom bombardment (FAB) mapping
Biology; Biochemistry
A technique for comparison of recombinant with natural proteins or with expected structures. A protein is cleaved by a specific enzymic (e.g. trypsin) or chemical (e.g. CNBr) method and the product ...
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 ...
