Evaluation by ELISA of anisakis simplex larval antigen purified by affinity chromatography.
In order to improve the specificity and sensitivity of the techniques for the human anisakidosis diagnosis, a method of affinity chromatography for the purification of species-specific antigens from Anisakis simplex third-stage larvae (L3) has been developed. New Zealand rabbits were immunized with A. simplex or Ascaris suum antigens or inoculated with Toxocara canis embryonated eggs. The IgG s...
متن کاملPurification by Affinity Chromatography
The glycine receptor of rat spinal cord was solubilized with the nonionic detergent Triton X-100 and subsequently purified by affinity chromatography on aminostrychnine-agarose and wheat germ agglutininSepharose. An overall purification of 1950-fold was achieved. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate and mercaptoethano1 revealed three glycine receptor-asso...
متن کاملPurification of equine infectious anemia virus antigen by affinity chromatography.
Affinity chromatography was performed to obtain highly purified antigen from equine infectious anemia (EIA) virus. After crude antigen was concentrated by polyethylene glycol precipitation of culture fluids from equine dermal cells persistently infected with EIA virus, and after the virus was disrupted with ether, it was added to a column of cyanogen bromide-activated Sepharose 4B to which EIA-...
متن کاملEvaluation by the skin prick test of Anisakis simplex antigen purified by affinity chromatography in patients clinically diagnosed with Anisakis sensitization.
Anisakis simplex crude extracts (CE) (IPI, ASAC and ALK-ABELLO), A. simplex larval antigens purified using a column of IgG anti-A. simplex (PAK) or a column of IgG anti-Ascaris suum (PAS), antigen eluted from columns of IgG anti-A. suum (EAS) and an A. suum adult CE were assayed by the skin prick test. Thirty percent of assayed patients showed a negative reaction in the Anisakis skin prick test...
متن کاملProtein Purification by Affinity Chromatography
The preparation of a number of agarose and polyacrylamide bead derivatives useful in the purification of proteins by afhnity chromatography is described. These techniques permit (a) the attachment of ligands to the gel through extended hydrocarbon chains which place the ligand at varying distances from the gel matrix backbone; (b) the covalent attachment of ligands to agarose or polyacrylamide ...
