Non-Functionalized Polystyrene 20.00µm
Specification range: 19.00 – 21.00µm
Delivery on this product is usually within 7 – 10 days.
We offer uniform polystyrene latex microspheres that may be used as-is for standards or markers, or coated with proteins via adsorption for use in diagnostic tests and assays. Our spheres are synthesized via emulsion polymerization, and are available in diameters from ~20nm-90µm, with typical size CVs of 5-10%. For applications that require highly stringent CVs (e.g. 2-5%), call for product availability. Most products are supplied as a 10% solids suspension (100mg/mL) in de-ionized water with surfactant and sodium azide.
Many proteins may be easily and stably absorbed to hydrophobic, non-functionalized microspheres. Divinylbenzene (DVB) confers additional solvent and heat resistance to our crosslinked spheres.
