Carboxylic Acid Functionalized PrecisionMRX® Nanoparticles Carboxylic acid functionality allows conjugation to molecules containing amine groups, such as proteins and peptides following our conjugation protocol. Size:10mg/50mg Description Water soluble, superparamagnetic magnetite nanoparticles with a core diameter of 24 – 26 nm and a low size dispersity (≤ 7%) as measured by Small Angle X-ray Scattering (SAXS). Nanoparticle cores are coated with a monolayer of oleic acid and a monolayer of an amphiphilic polymer with carboxylic acid functional groups displayed on the surface. Carboxylic acid functionality allows conjugation to molecules containing amine groups, such as proteins and peptides following our conjugation protocol. The hydrodynamic diameter of the particles is approximately 40 – 45 by Dynamic Laser Scattering (DLS) with a Polydispersity Index (PDI) of ≤ 0.1, and their zeta potential ranges from -60 to -70 mV. These particles are stable in most buffer solutions in the range of pH 4 – 10. Carboxylate-nps-SDS-v-1.31.pdf for Carboxylic Acid Functionalized PrecisionMRX® Nanoparticles |
