epoxy

sicastar® particles are available with epoxy groups on the surface in the size range from 300 nm to 20 µm. Proteins, antibodies or other target molecules can be directly bound by reaction of epoxy-functionalized particles in a conjugation buffer at pH=9 for conjugation with amino groups or at pH=7 for reaction with SH groups of your target molecules.
The particles are supplied as powder to preserve the reactivity of the epoxy groups.
