Description

Biotinylate reduced cysteines with this short, maleimide-activated, sulfhydryl-reactive biotinylation reagent containing a 2-unit PEG spacer arm to enhance water solubility.

Thermo Scientific™ EZ-Link Maleimide-PEG2-Biotin is a mid-length, maleimide-activated, sulfhydryl-reactive biotinylation reagent that contains a 2-unit ethylene glycol in its spacer arm for increased water-solubility characteristics.

  • Mid-length, maleimide-activated, sulfhydryl-reactive biotinylation reagent that contains a 2-unit ethylene glycol in its spacer arm for increased water-solubility characteristics.
  • Protein labeling - biotinylate antibodies or other proteins for use in protein methods
  • Thiol-reactive - reacts with sulfhydryls (-SH), such as the side-chain of cysteine (C)
  • Maleimide-activated - perform reactions at pH 6.5 to 7.5 in buffers such as PBS
  • Pegylated - spacer arm contains a hydrophilic, 2-unit, polyethylene glycol (PEG) group
  • Enhances solubility - pegylation imparts water solubility to the biotinylated molecule, helping to prevent aggregation of biotinylated antibodies stored in solution
  • Irreversible - forms permanent thioether bonds; spacer arm cannot be cleaved
  • Solubility - can be dissolved directly in aqueous buffers for labeling reactions
  • Medium length - spacer arm (total length added to target) is 29.1 angstroms

Frequently Asked Questions (FAQs)

How does a product with "No-Weigh" format reduce my concern over reagent stability?

The No-Weigh product format, where small amounts of reagent are pre-weighed and packaged separately, prevents the contamination and loss of reagent reactivity over time associated with repetitive opening and closing of a single vial. This format enables use of a fresh vial of reagent each time and eliminates the hassle of weighing out small amounts of reagent.
