Our Custom and Reliable Beta Glucan Analysis for Clients

Beta-glucans (β-glucans) are a category of β-D-glucose polysaccharides. Their physicochemical properties vary based on their source. Primarily composed of β-(1,3)/(1,6) branched glucan polymers, supplemented by varying quantities of β-(1,6)-glucan and chitin, these variations extend to molecular mass, solubility, viscosity, branching structure, and gelation properties, eliciting varied physiological effects in animals. Embark on cutting-edge analyses with CD BioGlyco's beta-glucan analysis service, leveraging our advanced analytical method, a robust research and development team, and reliable laboratory technicians. We offer high-quality identification and composition services for Pharmaceuticals tailored to your specific requirements.

• Composition test based on spectrophotometry and light-scattering

Here is the standard process of our test of beta-glucan content

• Firstly, conduct spectrophotometry and light-scattering beta-glucanase/glucosidase digestion by adding water to the sample, followed by the addition of glucose oxidase/peroxidase reagent.
• Next, place the vials in a 40°C incubator. Then, we measure the absorbance of each vial containing either the sample or standard solution against the enzyme blank solution.
• Afterward, we create a standard curve using the absorbance values of glucose standards. Utilizing the curve slope and absorbance values of the digested sample and standard solutions, ascertain the concentration (C) of liberated glucose in mg/mL.

Besides the content test of beta-glucan, we also test the content of protein and the content of fat.
