| spectrin | <protein> Membrane associated dimeric protein (240 & 220 kD) of erythrocytes. Forms a complex with ankyrin, actin and probably other components of the membrane cytoskeleton, so that there is a meshwork of proteins underlying the plasma membrane, potentially restricting the lateral mobility of integral proteins. Isoforms have been described from other tissues (fodrin, TW 240-260k protein), where they are assumed to play a similar role. Contains the EF hand motif. (18 Nov 1997) |

| spectrochemistry | The study of chemical substances and their identification by means of spectroscopy, i.e., by light emitted or absorbed. (05 Mar 2000) |
| spectrocolorimeter | A colourimeter using a source of light from a selected portion of the spectrum, i.e., of a selected wavelength. (05 Mar 2000) |
