Description

Biotinylate protein amines (e.g., lysines) with our shortest (13.5A), water-soluble, NHS-ester biotinylation reagent for antibody or cell-surface labeling.

Label antibodies, proteins and other molecules that have primary amines with Thermo Scientific™ EZ-Link Sulfo-NHS-Biotin, a short-chain, water-soluble biotinylation reagent.

Highlights:

  • Shorter spacer arm than Sulfo-NHS-LC-Biotin
  • Reacts with primary amines at pH 7-9 in non-amine-containing buffers such as borate, carbonate, or phosphate buffers
  • Negative charge of -SO3 keeps biotinylation localized at the cell surface so reagent does not pass through cell membrane
  • Water solubility eliminates the need for harmful organic solvents
U.S. Patents 5,892,628 and 5,872,261.

Frequently Asked Questions (FAQs)

How do the EZ-Link Micro Biotinylation Kits differ from the standard biotinylation kits?

The standard biotinylation kits contain components for labeling 1-10 mg of protein, and the Micro Biotinylation Kits are structured for labeling 50-200 µg of protein in 200-700 mL. The Micro kits contain the biotinylation reagents in small, individual packages and do not include components to perform the HABA assay.
Can you provide the shelf-life for EZ-Link Sulfo-NHS-Biotinylation Kit?

EZ-Link Sulfo-NHS-Biotinylation Kit is covered under our general 1-year warranty and is guaranteed to be fully functional for 12 months from the date of shipment, if stored as recommended. Please see section 8.1 of our Terms & Conditions of Sale (https://www.thermofisher.com/content/dam/LifeTech/Documents/PDFs/Terms-and-Conditions-of-Sale.pdf) for more details.
