产品描述： 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.

Features of EZ-Link Sulfo-NHS-LC-Biotin:

• 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 • Medium length—spacer arm (total length added to target) is 22.4 angstroms; provides excellent balance between adequate length

(minimal steric hindrance for biotin binding) and modest mass
