Thermo Scientific™ EZ-Link™ Sulfo-NHS-SS-Biotin, No Weigh Format
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.
$549.87 - $837.99
Description
Thermo Scientific™ EZ-Link Sulfo-NHS-SS-Biotin enables simple and efficient biotin labeling of antibodies, proteins and any other primary amine-containing biomolecules in solution.
- Protein labeling - biotinylate antibodies to facilitate immobilization, purification or detection
- Cell surface labeling - biotinylates only surface proteins of whole cells because the negatively charged reagent does not permeate cell membranes
- Amine-reactive - reacts with primary amines (-NH2), such as lysine side-chains, or the amino-termini of polypeptides
- Cleavable - disulfide bond in spacer arm allows the biotin label to be removed using reducing agents such as DTT; only a small sulfhydryl group remains attached to the molecule
- Soluble - charged sulfo-NHS group increases reagent water solubility compared to ordinary NHS-ester compounds
- Medium length - spacer arm (total length added to target) is 24.3 angstroms; it consists of the native biotin valeric acid group extended by a 7-atom chain
