Thermo Scientific™ EZ-Link™ Micro Sulfo-NHS-Biotinylation Kit
The Thermo Scientific EZ-Link Micro Sulfo-NHS-Biotinylation Kit contains reagents sufficient for 8 biotinylation reactions (e.g., 0.05–0.2 mg antibody per reaction). The EZ-Link Sulfo-NHS-Biotin reagent included in the kit is a short-chain, water-soluble biotinylation reagent used for labeling antibodies, proteins and other molecules that have primary amines.
Features
- Protein labeling—biotinylate antibodies to facilitate immobilization, purification or detection using streptavidin resins or probes
- 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
- Soluble—charged sulfo-NHS group increases reagent water solubility compared to ordinary NHS-ester compounds
- Irreversible—forms permanent amide bonds; spacer arm cannot be cleaved
- Very short—spacer arm (total length added to target) is 13.5 angstroms; it consists of the native biotin valeric acid group only.
