Biotin-HPDP

KEY FEATURES: • HPDP contains a dithiopyridyl group which is reactive towards sulfhydryl groups (-SH) such as in cysteine (C) side chain to form stable disulfide bond • Contains a spacer arm with a length of 29.2 Å that prevents steric hindrance to biotin labeling • The spacer is cleavable at the disulfide bond with reducing agent, such as DTT, TCEP, etc. • Must be dissolved in an organic solvent such as DMF or DMSO before dilution with aqueous buffers APPLICATIONS: • Ideal for biotinylating antibody or protein for use in protein detection, purification or immobilization
