MBS crosslinker (m-Maleimidobenzoyl-N-hydroxysuccinimide ester) is a non-cleavable, water insoluble, heterobifunctional protein crosslinking reagent that is commonly used to crosslink haptens to carrier proteins and enzymes to antibody. The MBS crosslinking reagent's NHS ester and maleimide reactive groups react with amino and sulfhydryl moites, respectively. Sulfo-MBS crosslinker is the water soluble analog of MBS protein crosslinker and is a convenient choice if you do not wish to use organic solvents to solubilize MBS protein crosslinking reagent. The MBS protein crosslinker extended spacer arm analog is SMPB crosslinker SATA Protein Modifier can be used to add sulfhydryl groups (thiols, -SH) to proteins or peptides prior to MBS crosslinking.

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.
