GMBS crosslinking reagent, also known as N-(Gamma-Maleimidobutyryloxy) Succinimide, is a non-cleavable, water insoluble, heterobifunctional protein crosslinker. GMBS crosslinking reagent is commonly used to crosslink haptens to carrier proteins or enzymes to antibody. GMBS crosslinking reagent's short spacer arm length of 7.3 angstroms and is less immunogenic than the MBS crosslinking reagent analog. GMBS crosslinking occurs via NHS ester and maleimide reactive groups which react with amino and sulfhydryl moites, respectively. GMBS Crosslinker is useful for making antibody drug conjugates (ADCs).

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.
