Thermo Scientific EZ-Link Sulfo-NHS-LC-LC-Biotin enables simple and efficient biotin labeling of antibodies, proteins, and any other primary amine–containing macromolecules. Specific labeling of cell surface proteins is another common application for these uniquely water-soluble and membrane impermeable reagents.
- 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 the side-chain of lysines (K) 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
- Doubly long —spacer arm (total length added to target) is 22.4 angstroms; this extended arm helps to minimize steric hindrance for biotin binding
Thermo Scientific No-Weigh products are specialty reagents provided in a pre-aliquoted format. The pre-weighed packaging prevents the loss of reagent reactivity and contamination over time by eliminating the repetitive opening and closing of the vial. The format enables use of a fresh vial of reagent each time, eliminating the hassle of weighing small amounts of reagents and reducing concerns over reagent stability.
Sulfo-NHS-LC-LC-Biotin is the longest of three very similar EZ-Link Reagents that are water-soluble, non-cleavable, and enable simple and efficient biotinylation of antibodies, proteins and any other primary amine-containing macromolecules in solution. Specific labeling of cell surface proteins is another common application for these uniquely water-soluble and membrane impermeable reagents. Differing only in their spacer arm lengths, the three Sulfo-NHS-ester reagents offer the possibility of optimizing labeling and detection experiments where steric hindrance of biotin binding is an important factor.
