Using patented and proprietary technology, Magsphere's products are mostly monodispersed and available in diameter ranges from 0.02 um (20 nm) to 20 um. Our production method utilizes emulsion polymerization or seeded emulsion polymerization techniques to produce spherical, stable, ultra-clean, uniform latex particles. Aside from our basic white polystyrene latex particles, we also produce intensely dyed colored particles (blue, red, green), fluorescent particles (blue, red, orange, yellow-green), and surfactant free latex particles. Latex particles are also available in numerous surface chemistry groups including carboxyl, amine, epoxy, and chloromethyl functionalities.
Our magnetic particles, or magnetic beads, are synthesized by embedding superparamagnetic iron oxide crystals into a polystyrene matrix. They are specially designed for use either with hydrophobic surfaces for protein adsorption or with carboxylic acid groups on their surface for covalent conjugation. Three convenient sizes of magnetic particles (average size of, 0.8um, 2um and 5um) are ideal for magnetic cell separation, automated immunoassays, and concentration or purification of peptides or proteins from biological samples.
Magsphere Inc. has now extended its product line into the cytometer field. We offer QC alignments beads, linearity beads, and blank beads which can be used for various applications that may fit your needs. These new products have specific excitations and emission properties that may encompass the desired PMT reading.
Magsphere cytometer results are measured by BD LSRFortessaTM and analyzed by BD FACSDivaTM. Size and bead counts are measured by ZTM Series COULTER COUNTER® and COULTER N4 Plus.
If you have any unusual size, color, or functionality requirements that are not listed as a standard product, our highly qualified technical team will carry out a full-custom synthesis for you. This usually can be completed within 7 to 10 working days. Looking for a custom product? Contact us at customers@magsphere.com.
