NHS-S-S-dPEG®₄-biotin (cleavable)




NHS-S-S-dPEG®4-biotin, product number 10194, combines biotin with the highly useful properties of single molecular weight discrete polyethylene glycol (dPEG®), a cleavable disulfide linker, and the amine-reactive functionality of N-hydroxysuccinimidyl (NHS) ester. NHS-S-S-dPEG®4-biotin has numerous applications.

Quanta BioDesign’s dPEG® Technology

Unlike traditional polyethylene glycol (PEG), which is a disperse polymer (Ð > 1), all of Quanta BioDesign’s dPEG® products are single molecular weight products containing a discrete chain length of PEG as a linker, spacer, or modifier. Consequently, our dPEG® products create uniform conjugates. These conjugates exhibit a more straightforward analysis compared to traditional polymer PEG products.

Biotinylation with dPEG® Products

Biotinylation is the process of attaching biotin to a biomolecule or surface. This process finds extensive use in biotechnology, medical diagnostics, and many other applications. Typical biotinylation reagents such as LC-biotin are hydrophobic. This hydrophobicity creates problems when biotinylating biomolecules since the biomolecular conjugates can precipitate from aqueous solution.

Act Now

Stop using inferior biotinylation reagents! Sure, many other people use LC-biotin products, but you can do better. Our biotinylation reagents offer water solubility, improved hydrodynamic volume, no background noise (which means better signal), and no protein precipitation caused by aggregation. Why would you not use something better?
