Thermo Scientific™ EZ-Link Sulfo-NHS-LC-LC-Biotin is a long-chain biotinylation reagent for labeling antibodies, proteins and other molecules that have primary amines.Additional Information and Online Ordering »Thermo Scientific No-Weigh products are specialty reagents provided in pre-aliquoted format. The pre-weighed packaging helps prevent loss of reagent reactivity and contamination over time by minimizing repetitive opening and closing of vial. The format enables use of fresh vial of reagent each time, eliminating hassle of weighing small amounts of reagents and reducing concerns over reagent stability.Protein labeling: Biotinylate antibodies to facilitate immobilization, purification or detection using streptavidin resins or probesCell surface labeling: Biotinylates only surface proteins of whole cells because negatively charged reagent does not permeate cell membranesAmine-reactive: Reacts with primary amines (-NH2), such as side-chain of lysines (K) or amino-termini of polypeptidesSoluble: Charged sulfo-NHS group increases reagent water solubility compared to ordinary NHS-ester compoundsIrreversible: Forms permanent amide bonds; spacer arm cannot be cleavedDoubly long: Spacer arm (total length added to target) is 22.4A0; this extended arm helps to minimize steric hindrance for biotin binding
