Sulfo-MBSCrosslinker is a non-cleavable, water-soluble, heterobifunctional protein crosslinking reagent. It is commonly used to crosslink haptens to carrier proteins and enzymes to antibodies.
SMPB crosslinker is a heterobifunctional protein crosslinking reagent that is reactive toward sulfhydryl and amino groups. The SMPB protein crosslinker is an extended chain length analog of MBScrosslinker. SMPB crosslinker's spacer arm is non-cleavable.
