BioReady Gold Nanospheres – NHS (Dried Kit)

NHS-activated 40 nm gold is provided dried with conjugation kit components that make initial conjugation sweeps easy – no EDC/NHS activation required, just add purified antibody and follow our simple protocol (below).

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

Kit includes:

  • Lyophilized gold nanospheres that reconstitute to 20 OD; 50 µL per small unit and 500 µL per large unit
  • Easy-to-use detailed protocol (also available below to view before you buy)
  • Desalting buffer for antibody, reaction buffer, quencher, and conjugate diluent
  • Amicon® Ultra .5 mL spin filters for antibody buffer exchange/desalt

Small reaction kits generally require approximately 2 µg of purified antibody per unit, while the large reaction kit generally requires approximately 25 µg of purified antibody per unit.


Materials are shipped ambient. Store with desiccant at –20°C upon receipt. Avoid freeze-thaw cycles.
