Absolute Mag™ HPTA Magnetic Particles, 0.75 µm (# WHM-C022) are aqueous dispersion of magnetic silica particles containing 2 hydoxypropyl trimethylammoniumchlorid (HPTA). They are reversibly to charged groups of biomolecules and can be eluted with salt- or pH-gradient. This superparamagnetic particles are widely used as strong anion exchanger. Anion-exchange magnetic particles bind selectively to the negatively charged membrane groups of cells, bacteria or viruses which can be separated by magnetic forces. https://www.cd-bioparticles.com/p/HPTA-Magnetic-Particles_20_196_243_803.html
Creative Diagnostics provides highly uniform nanoparticles widely used in biology and medicine, including colloidal gold nanoparticles, silver nanoparticles, silica nanoparticles, titania nanoparticles, inorganic fluorescent nanoparticles (quantum dots and upconversion nanocrystals), as well as biodegradable polymer nanoparticles. Our nanoparticles are manufactured with different shapes and sizes, and the particle surface can be coated, functionalized or conjugated with biomolecules. These nanoparticles have found broad applications in immunoassay, bioseparation, medical imaging and diagnosis, as well as drug delivery and cancer therapy.
