Q: How many streptavidin molecules are on each SHS iron oxide nanocrystal?
A: The number of streptavidin molecules depends on the size of the SHS iron oxide nanocrystals. Please call our customer service for detailed information.
Q: What is the storage solution for your SHS iron oxide solutions?
A: The storage solution is Ocean's standard storage buffer (catalog: MWB-100), which contains a proprietary formulation with proteins in aqueous borate buffered solution at pH 7.4+0.1 and 0.02%NaN3.
Q: Can I use magnetic separator to purify the SHS iron oxide nanocrystals after they are conjugated with biomolecules?
A: Yes. You can use our specially designed magnetic separator SuperMag SeparatorTM to purify if sizes are larger than 10 nm.
Q: How do I purify the SHS iron oxide nanocrystals to remove the reaction regents and the excess protein after conjugation?
A: Yes. You can use our specially designed magnetic separator SuperMag SeparatorTM to purify if sizes are larger than 10 nm.
Q: Can I use biotinylated antiobodies to conjugate with the SHS crystals?
A: Please note, for biotinylated antibody conjugation to our streptavidin conjugated nanocrystals, only use mono-biotinylated antibodies. Otherwise, if multiple biotin-labeled antibodies are used, it may cause precipitation of the nanocrystals. For additional information, please contact us at (479)751-5500 or email us at
