Biotin-X, succinimidyl ester *CAS 72040-63-2*

Biotin-X, succinimidyl ester

CAS 72040-63-2

This biotin has a spacer arm of ~22 Å that reduces steric hindrance when binding several biotinylated molecules to one avidin complex; This reagent penetrates cell membranes because there is no charged group.
