Catalog No. PIA39261

Description

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
