Luminescence spectroscopic approaches in studying cell surface dynamics.

摘要: The major elements of membranes, such as proteins, lipids and polysaccharides, are in dynamic interaction with each other (Alberts et al. 1983). Protein diffusion the lipid matrix membrane, domain formation below above their transition temperature from gel to fluid state, have many functional implications. This type behaviour membranes is often summarized one frequently used word membrane fluidity (coined by Shinitzky & Henkart, 1979). cell includes rotational, translational segmental movements (or domain-like associations) plane of, perpendicular membrane. ever changing proximity relationships form a pattern lipids, proteins saccharide moieties usually described ‘cell-surface dynamics’ (Damjanovich 1981). knowledge about defined originates experiments performed mostly on cytoplasmic eukaryotic cells. Nevertheless numerous data available also mitochondrial nuclear well endo (sarco-)plasmic reticulum (Martonosi, 1982; Slater, 1981; Siekevitz,
