Description:

Nanocs SnapLink pegylated Biotin NHS is a water soluble, amine reactive derivative of biotin. SnapLink Biotin PEG NHS enables simple and efficient biotin labeling of proteins, antibodies or other amine containing molecules or particles. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility that is transferred to the biotinylated molecules , thus reducing aggregation of labeled substrates in solution. The PEG spacer arm also gives the biotin a long and flexible structure to minimize steric hindrance for binding to streptavidin or avdins. N-hydroxysulfosuccinimide NHS esters of biotin react efficiently with primary amino groups (-NH2) in alkaline buffer to form a stable amide bond. Nanocs provides a variety of high purity biotin and its derivatives for various biotinylation and bioassay applications. These functional biotin products were purified by chromatography to remove impurities and ensure adequate applications both in-vitro and in-vivo.
