CD Bioparticles announces the launch of colored polystyrene …












With years of experience in the pharmaceutical and life sciences industry, CD Bioparticles now releases colored polymer particles in a wide range of sizes that can be used in lateral flow detection and latex agglutination assays. Additionally, these DiagPoly™ colored polymer particles can be modified with functional groups or ligands such as amine, carboxyl, protein A, protein G, streptavidin, goat anti-human IgA, l goat anti-human IgG, goat anti-mouse IgG and human IgG. IgG.

CD Bioparticles has developed a wide range of polystyrene micro- and nanoparticles, using emulsion and non-emulsion polymerization processes. Meanwhile, coated or conjugated particles are prepared either by passive adsorption or by covalent coupling. Functionalized polystyrene nanoparticles and polystyrene particles can be used in a variety of applications such as drug delivery materials, bioimaging, markers, and immunoassays. With superior stability, high binding capacity and ultra-high specificity (low background), polystyrene latex particles have been extensively validated in academic and industrial scale immunoturbidimetric assays.

CD Bioparticles now offers uniform, monodisperse colored polymer particles in a wide range of sizes for the research community. These colored polymer particles are often used in lateral flow detection and latex agglutination tests. They are also frequently used as markers to label biomolecules. The carboxylated colored polystyrene particles allow the covalent coupling of antibodies or antigens. Anti-Escherichia coli Abs conjugated polystyrene particles (latex beads) can be used in agglutination tests and are often used in tandem with bacteria identification tests to confirm the presence of specific bacteria in samples.

DiagPoly™ colored polymer particles from CD Bioparticles can be modified with functional groups or ligands. Additionally, colored polymer particles conjugated to recognition molecules such as antibodies, antigens, proteins or other biomacromolecules are available upon request. Unmodified polymer spheres are also available from CD Bioparticles. These polymer particles find many applications in a range of flow analysis, diagnostic testing, testing and calibration of optical and electronic instruments.

DiagPoly™ Colored Polymer Particles at CD Bioparticles are monodisperse without agglomeration or aggregation, with little or no leakage and availability for modification. These polymer particles are advanced by wide size ranges to meet the different and varied research needs of global customers. For example, DiagPoly™ Blue Coloured, Amine Polystyrene Particles, 0.1 µm (Cat. No. DDAB-V001) are blue colored polystyrene particles functionalized with an amine for qualitative and quantitative detection, and are suitable for flow testing lateral and latex agglutination tests.

CD Bioparticles offers a wide selection of monodisperse polymer nanoparticles and microspheres in multiple sizes, from 20 nm to 100 µm. For more information on these colored polymer particles or to discuss your current project, please visit CD Bioparticles at https://www.cd-bioparticles.com.
