tuberculosis remains as an important socioeconomical and medical problem throughout the world and especially in iran. early and timely diagnosis of pulmonary and extrapulmonary tuberculosis is vital to initiate prompt treatment. current diagnostic methods are either slow or lack enough sensitivity or specificity. several mycobacterial antigens are involved in the complex interaction with the im...
introduction: foot-and-mouth disease (fmd) is a highly contagious and economically devastating viral disease of livestock that is categorized in list a of animal diseases by the world organisation for animal health (oie). vaccination is effective against fmd and the vaccine production centers largely use the industrial ultra-filtration and chromatography in order to remove the cellular proteins...
In the characterization of polymers, size-exclusion chromatography (SEC) has become a standard technique for determining molar mass averages andmolar mass distributions (MMD) of polymers. The principle of SEC is easily understood: owing to limited accessability of the pore volume within the particles of the column packing, polymer molecules are separated according to their hydrodynamic volumes,...
Separation of macromolecules on the basis of their molecular weight by size exclusion chromatography has long been considered to be caused by the geometry-dependent partition of macromolecules between a continuous phase and the porous interior of a gel or cross-linked bead. The volume of a pore accessible to a solute is limited by its relative dimensions, so larger molecules will have access to...
