SMPB crosslinker, or N-Succinimidyl 4-[4-maleimidophenyl]butyrate, is a heterobifunctional protein crosslinking reagent that is reactive toward sulfhydryl and amino groups. SMPB crosslinker's spacer arm is non cleavable. The SMPB protein crosslinker is an extended chain length analogue of MBS crosslinker. References: Myers DE, Uckun FM, Swaim SE, Vallera DA.
