DSS crosslinker, or Disuccinimidyl suberate, is a homobifunctional crosslinker that is cell membrane permeable. DSS crosslinker has amine-reactive NHS esters at both ends of an 8-atom (11.4 angstrom) spacer arm that are used to conjugate proteins. DSS crosslinker can be used to conjugate or crosslink intracellular proteins.

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.
