產(chǎn)品簡介:
NHS-PEG12-Biotin is very long, pegylated biotinylation reagent for simple and efficient biotin labeling of antibodies, proteins and other primary amine-containing macromolecules.These compounds have polyethylene glycol (PEG) spacer arms that enhance the reach and solubility of labeled molecules.NHS-PEG12-Biotin is a very long (56.0Å), pegylated, water-soluble, NHS-ester biotinylation reagent to label amines and maximize solubility of antibodies and other proteins. The N-hydroxysuccinimide ester (NHS) group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility that is transferred to the biotinylated molecule, thus reducing aggregation of labeled proteins stored in solution. The PEG spacer arm also gives the reagent a long and flexible connection to minimize steric hindrance for binding to avidin molecules.
我公司交聯(lián)劑特點:
