SVP is a group of autoclaved water soluble iron oxide nanocrystals with amphiphilic polymer coating. SVP has been autoclaved at 121 ° for 30 mins, which is suitable for experiments that require enzyme-free conditions.
Their surface functional group is carboxylic acid and their zeta potential is from -30mV to -50mV. Their organic layers consist of a monolayer of oleic acid and a monolayer of amphiphilic polymer. The overall thickness of the organic layers is about 4 nm. The hydrodynamic size of the nanocrystals is about 8-10 nm larger than their inorganic core size measured by TEM.
SVP is very stable in most buffer solutions in the pH range of 4-10. SVP can be conjugated to protein, peptide and DNA by following our standard conjugation protocol.
