Adsorption

Adsorption

1. (Science: chemistry) The accumulation or concentration of molecules of a gas or liquid on a surface in contact with the gas or liquid, resulting in a relatively high concentration of the gas or solution at the surface. Note that the accumulating molecules do not actually penetrate the substance they are on.

Compare: absorption.

2. (Science: virology) The adhesion of a substance to an organic particle in a solution, for example the adhesion of a virus to a cell.

Origin: L. Sorbere = to suck

Invasion of a host cell by a DNA virus

... cell that has complimentary receptors to its “anti-receptors”, when found it joins to a specific receptor site on the host cell it does this by adsorption where glycoproteins on the viral envelope adsorb to complimentary receptors on the host cells membrane, it does this by tricking the cell ...

Is an ELISA plate really specific for protein adsorption?

Not lipids, DNAs, etc. ? What about lipoproteins and glycoproteins? Could anybody provide some basis for this specific interactions of protein molecules w/ surface groups at the bottom of the ELISA plate wells? Or links to some orginal research papers? Thanks.

Protein precipitation

... other acidic barium are used to precipitate albumin instead of to recover it? Barium will attach and cover albumin molecules surface (yes, it is adsorption), so that it cannot dissolve/being precipitated? :?
