Stevia is a perennial herb and all of the plant parts has strong sweet taste. Extracts of Stevia is low in calories and used as an excellent healthy substitute for sugar and artificial sweeteners. The crude extracts are typically purified by filtration, resin adsorption, de-coloration followed by multiple recrystallization. [...]

Gel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC), that separates analytes on the basis of size.  It is often necessary to separate polymers, both to analyze them as well as to purify the desired product. GPC systems and consumables are now also available from a [...]

Protein A affinity chromatography medium by EPRUI is based on the monodisperse porous poly (methyl methacrylate) (PMMA) microspheres as the matrix, and genetically modified protein A as the ligand, which ensures its high affinity binding of monoclonal antibodies and Fc fragment containing recombinant proteins (macromolecules). Our protein A chromatography [...]

Fullerenes as advanced materials has broad potential applications in various industries. Its unique cage structure leads to interesting and extraordinary magnetic, superconductive, optical and catalytic properties. However, the application of fullerenes has been restricted because of the difficulty in the synthesis and especially purification of fullerenes. EPRUI Biotech has [...]

Silica gel chromatography packing is made of monodisperse porous silica microspheres with highly uniform particle size, perfect spherical morphology and optimized pore structure. Our silica gel chromatography media meets the requirements of high performance liquid chromatography (HPLC) analysis in the laboratory and preparative separations in industry scale. The monodisperse [...]

Ion Chromatography (or ion-exchange chromatography) is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. The matrix of EPRUI’s ion chromatography is highly cross linked polyacrylic microspheres with a hydrophilic coating. The most commonly used ion exchange matrix is cellulose, sepharose [...]

EPRUI Biotech offers a series of hydrophobic interaction chromatography (HIC) media which is used to separate and purify proteins and peptides with high efficiency. Hydrophobic interaction chromatography media is used to separate proteins on the basis of relative hydrophobicity. The working principle of HIC is that hydrophobic groups on [...]
