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.
