Biotin‐PEG4‐NHS Ester

Catalog ID Size Pricing
B-720-25 25 mg $ 110.00
B-720-100 100 mg $ 225.00

Description

Biotin‐PEG4‐NHS Ester is a pegylated, highly hydrophilic biotinylation reagent for simple and efficient biotin labeling of antibodies, proteins and other primary amine-containing biomolecules.

Biotin‐PEG4‐NHS Ester reacts specifically and efficiently with primary amines (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form covalent bonds. The hydrophilic polyethylene glycol (PEG) spacer arm of this reagent imparts water solubility that is transferred to the labeled 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 involved with binding to avidin molecules.

6820-01-500 500 μg $ 939.00

Description

Hepatitis B virus (HBV) is an infectious, and potentially fatal, human disease that causes serious liver disease. There are three start codons on the Gene S HBV surface protein antigen (HBsAg) that divide the gene into three sections: pre-S1, pre-S2, and S. These start sites create three carboxyl, coterminal polypeptides that are called large (LHB, the order from surface to the inside: pre-S1, pre-S2, and S), middle (MHB, containing the pre-S2 and S portion) and small (SHB, covering only the S portion). The pre-S1 amino acid region of LHBs consists of 119 amino acids and has been shown to interact with its human binding partner, γ2-adaptin, to subvert the membrane-trafficking apparatus to mediate virion export. HBsAg-PreS1 can be used for Immunochromatography, monoclonal and polyclonal antibody preparation or for ELISA analysis.
