Biotin-PEG11-oxyamine HCl salt is an aldedye reactive biotin probe. It contains an oxyamine group that can react with an aldehyde to form a reversible oxime bond. If reduced, the oxime can be converted to a stable carbon-N bond. The hydrophilic PEG spacer increase the water solubility of the biotinylated molecule.
