Use of gel filtration to examine the distribution of calcium among serum proteins.

Comparison of two gel filtration chromatography resins for the purification of foot-and-mouth disease virus as a purified vaccine antigen

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...

Distribution of the serum proteins of Syrian hamster as revealed by Starch gel electrophoresis

Separation and quantitation of serum constituents associated with calcium by gel filtration.

Gel filtration of serum by use of polyacrylamide beads (Biogel P-2) separates total colcium into four distinct peaks: an initial peak, corresponding to protein-bound calcium; a second peak containing the calcium complexes of citrate, phosphate, lactate, and sulfate; a third peak containing calcium bicarbonate; and a fourth peak or trough corresponding to the serum ionic calcium. An eluent conta...

Role of Molecular Interactions and Oligomerization in Chaperone Activity of Recombinant Acr from Mycobacterium tuberculosis

Background: The chaperone activity of Mycobacterium tuberculosis Acr is an important function that helps to prevent misfolding of protein substrates inside the host, especially in conditions of hypoxia. Objectives: The aim of this study was to establish the correlation of structure and function of recombinant Acr proteins both before and after ge...

Elution patterns of rubella IgM, IgA, and IgG antibodies from a dextran and an agarose gel.

The elution pattern of serum proteins and the distribution of rubella HAI activity in 95 sera from 65 cases were determined after gel filtration with (a) Sephadex G-200 and (b) Bio-Gel A-5M. Rubella HAI antibody in peak 1 after Sephadex G-200 fractionation of early convalescent sera consists of both IgM and high molecular weight IgA. However, these two classes of antibody can be distinguished b...
