In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent: washing of loaded ion-exchange...

An antibody elution is a clinical laboratory diagnostic procedure which removes sensitized antibodies from red blood cells, in order to determine the...

desorbed by an elution buffer. The mode used for elution (expanded-bed versus settled-bed) depends on the characteristics of the feed. After elution, the adsorbent...

gel (stationary phase). To determine approximate molecular weight, the elution volumes of compounds with their corresponding molecular weights are obtained...

pre-incubated drugs should mirror the elution profiles of the targets they complex with. Correlation of drug and protein elution profiles allows for targets to...

known (see Mark–Houwink equation), a plot of log [η]M versus elution volume (or elution time) for a particular solvent, column and instrument provides...

histidine and is typically used at a concentration of 150 - 500 mM for elution. Histidine or histamine can also be used. Decrease in pH When the pH decreases...

prepare for subsequent rounds of selection in which the stringency of the elution conditions can be increased to identify the tightest-binding sequences...

divided into solvent selectivity groups. Using solvents with different elution strengths or different selectivity groups can often give very different...

binding of biotinylated DNA to streptavidin-coated magnetic beads and elution of single DNA strands selectively using alkali. The method allowed robotic...

the result of the first application of rate theory to the chromatography elution process. The van Deemter equation relates height equivalent to a theoretical...
