Thermo Scientific™ EZ-Link™ Sulfo-NHS-LC-Biotin is an intermediate-length, water-soluble biotinylation reagent for labeling antibodies, proteins and other molecules that have primary amines.

Biotinylate reduced cysteines (-SH groups) at high pH via irreversible thioether bonds with this haloacetyl-activated, sulfhydryl-reactive biotinylation reagent.

Thermo Scientific™ EZ-Link™ Sulfo-NHS-Biotin is a short-chain, water-soluble biotinylation reagent for labeling antibodies, proteins and other molecules that have primary amines.

Biotinylate reduced cysteines (-SH groups) at high pH with this haloacetyl-activated, sulfhydryl-reactive biotinylation reagent containing polyethylene glycol for solubility.

Biotinylate reduced cysteines with this short, maleimide-activated, sulfhydryl-reactive biotinylation reagent containing a 2-unit PEG spacer arm to enhance water solubility.

Thermo Scientific™ EZ-Link™ Sulfo-NHS-SS-Biotin No-Weigh™ Format is a water-soluble, NHS-ester biotinylation reagent whose spacer arm includes a cleavable disulfide bond for reversible labeling of proteins and cell surface primary amines.

Chemically tag purified proteins at primary amines to covalently crosslink and transfer biotinylation to protein interaction binding partners.

Biotinylate reduced cysteines (-SH groups) with a maleimide-activated, sulfhydryl-reactive biotinylation reagent containing a stabilizing cyclohexane group in the spacer arm.

Biotinylate reduced cysteines with this long, maleimide-activated, sulfhydryl-reactive biotinylation reagent with an 11-unit PEG spacer arm to enhance solubility and reach.
