Sulfhydryl Biotinylation Reagents

Sulfhydryl Biotinylation Reagents are cleavable pyridyldithiol and iodoacetyl activated biotin labeling reagents to specifically biotinylate antibodies and other proteins or peptides at sulfhydryl groups, such as reduced free thiols on cysteine residues.
Biotin-HPDP is a pyridyldithiol-activated, sulfhydryl-reactive biotinylation reagent that conjugates via a reversible disulfide bond to enable use in a variety of purification methods.
Iodoacetyl-LC-Biotin is a mid-length, iodoacetyl-activated, sulfhydryl-reactive biotinylation reagent that forms stable, irreversible thioether bond at alkaline pH.

  2. A8009 Iodoacetyl-LC-Biotin Iodoacetyl-LC-Biotin (N-iodoacetyl-N-biotinylhexylenediamine), a sulfhydryl-reactive biotinylation agent, is a water-insoluble reagent that requires the dissolution of suitable solvents, including dimethyl sulfoxide (DMSO) and dimethylformamide (DMF), prior to the addition into aqueous reactions.
  3. A8008 Biotin-HPDP Biotin-HPDP (N-[6-(biotinamido)hexyl]-3’-(2’-pyridyldithio)propionamide), a sulfhydryl-reactive biotinylation agent, is  a water-insoluble reagent that requires the dissolution of suitable solvents, including dimethyl sulfoxide (DMSO) and dimethylformamide (DMF),  prior to the addition into aqueous reactions.
