Thermo Fisher, A39265, EZ-Link™ Sulfo-NHS-LC-Desthiobiotin, No-Weigh™ Format

Quantity: 5 x 1 mg
Unit Size: Each
• Long-chain, amine-reactive labeling reagent whose biotin-like group is elutable from streptavidin, making it ideal for purified or cell surface protein labeling and purification
• Desthiobiotin - analog of biotin allows easy elution from streptavidin, an ideal feature for affinity purification applications
• Protein labeling - tag antibodies or proteins in purified or mixed samples to enable high recovery in pull-down assays with streptavidin beads
• Cell surface labeling - modifies 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
