FAQs

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: 10 mM Tris buffer,1mg/ml BSA 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 info@oceannanotech.com
