Sulfo-MBS Crosslinker 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 MBS crosslinker. SMPB crosslinker's spacer arm is non-cleavable.
