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.

OurdPEG® 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.
