Use the BioReady Passive Conjugation Kit to conjugate any proteins to 40 nm and 80 nm bare citrate OD 20 gold particles.

Kit components:

  • BioReady 40 nm bare citrate gold, OD 20, 5 mL*
  • BioReady 80 nm bare citrate gold, OD 20, 5 mL*
  • Titration buffers covering pH 6.–9.7, 1 mL each
  • Blocking buffer, 5 mL*
  • Conjugate diluent, 5 mL*
  • 10% NaCl for salt test, 5 mL*

* Due to the current global supply shortage of bottles and caps, some reagents may be provided in different bottle types and capacities, with 5–10 mL of reagent included.

Our conjugation kit provides the flexibility to conjugate at any OD from 1 to 20. See Protocol below for more information.
