BS3 Crosslinker, or Bis[sulfosuccinimidyl] suberate, is an amine-reactive, water soluble, homobifunctional protein crosslinker. The 8-atom spacer arm of the BS3 crosslinking reagent is non-cleavable and the molecule is not cell membrane permeable. The BS3 protein crosslinker can be used to prepare antibody-protein conjugates, for crosslinking cell surface proteins, and for covalently orienting antibody to an immobilized Protein A or Protein G resin.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
