BioReady Gold Nanospheres – Streptavidin·

Streptavidin tetramer is covalently bound to the particle surface via an amide bond. 40 nm streptavidin gold conjugates can be used for convenient conjugation of any biotinylated antibody, protein or oligonucleotide.

BioReady products are specially formulated for the attachment of a molecular recognition element such as an antibody for lateral flow and biodiagnostics. Learn more ❯

Provided at 10 OD in an aqueous conjugation buffer composed of 0.1× PBS, 0.5% BSA, and 0.05% azide.
