Abstract:
An exo-polysaccharide derived from a Saccharomyces spp. strain is provided to enhance various activities of neutrophil, macrophage and lymphocyte, thereby being widely applied to an animal immunity-enhancing agent, a vaccine supplemental additive and an adjuvant therapeutic agent. An animal immunity enhancing agent comprises exo-polysaccharides extracted from a culture material of a Saccharomyces spp. strain. A method for preparing the exo-polysaccharides derived from the Saccharomyces spp. strain comprises the steps of: (a) after suspending pure colonies obtained by culturing the Saccharomyces spp. strain in sterile saline solution, inoculating 1 ml of the suspension into 1,000 ml of yeast malt broth and culturing it at a temperature of 28 deg.C for 72 hours; (b) after adding two times amount of distilled water into a culture material obtained from the step(a) and mixing it, boiling the mixture at a temperature of 100 deg.C for 1 hour and centrifuging the boiled mixture under 5,000xg for 30 minutes to collect supernatant therefrom; and (c) after adding two times amount of ethyl alcohol to the supernatant and mixing it, leaving a mixture in a cool chamber at a temperature of 4 deg.C for 2 days and collecting precipitated polysaccharides therefrom.
Abstract:
A plate agglutination tester and a method for measuring an immuno-reaction using the same are provided to decrease error of the result analysis in accordance with proficiency of a person performing diagnosis, show the degree of various immuno-reactions in an objective value and perform various statistical analyses, thereby being very useful for measuring the immuno-reaction. A plate agglutination tester consists of a transparent film and is characterized in that a section, which consists of a plurality of circles and where an antigen-antibody agglutination reaction occurs, is arranged and formed in horizontal and vertical directions on an upper side of the film. A method for measuring an immuno-reaction comprises the steps of: (a) mixing an antigen and an antibody specifically bound to the antigen with the plate agglutination tester to induce an agglutination reaction; (b) scanning the agglutination reaction induced plate agglutination tester and converting a scanning result into an image file; and (c) analyzing the obtained image file using a computer program capable of detecting fine agglutination reactants to numberize the intensity of the agglutination reaction. Further, the transparent film is an over head project film.
