Sieve
Definition:
(n.) A utensil for separating the finer and coarser parts of a pulverized or granulated substance from each other. It consist of a vessel, usually shallow, with the bottom perforated, or made of hair, wire, or the like, woven in meshes.
(n.) A kind of coarse basket.
Example Sentences:
(1) The test is based on the ability of larvae to freely migrate through selected mesh sizes of nylon sieves and the reduced ability of larvae to migrate after preincubation with, and in the presence of, substances that inhibit or reduce larval motility.
(2) The described procedure has the advantage of not requiring either molecular sieve or affinity chromatography for purification of homogenous CRP from human sera.
(3) When the capacitation medium was supplemented with follicular fluid, the [3H]sterols were bound to HDL's and to the albumin fraction; when the latter fraction was analysed by molecular sieve chromatography, 60-70% of the radioactivity eluted in fractions with a mean molecular weight corresponding to that of human serum albumin.
(4) When deformability was measured by filtration through 3-mum polycarbonate sieves, marked decreases in deformability were found in complement-coated erythrocytes.
(5) Rat liver cathepsin D (EC 3.4.23.5) was purified using precipitation technique, ion exchange chromatography, molecular sieve chromatography and isoelectric focusing.
(6) Analysis of the CNBr peptides on an HPLC sieving column confirmed that the electrophoretically abnormal peptides were of a higher molecular weight than were control peptides.
(7) The half-life of the solubilized oxidoreductase stored at 2-4 degrees C in the presence of 25% glycerol at pH 8.6 is approximately 30 h. The oxidoreductase contains a flavoprotein identifiable by its fluorescence spectrum for FAD which binds weakly to concanavalin A-Sepharose and elutes from gel sieving columns at a molecular weight range of approximately 51,000.
