BioReady Gold Nanospheres – Bare (Citrate)·

Citrate is the most common stabilizer used for passive conjugation to gold. The “bare” particle surface is stabilized with weakly-associated citrate molecules that can be easily displaced for passive conjguation. Learn more ❯

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 20 OD in aqueous 0.02 mM sodium citrate.
