Biotin

Biotinylation involves covalently attaching biotin to a protein, antibody or other primary amine-containing molecules, and allows for protein detection or purification using affinity chromatography. Biotin is often chosen for appropriate applications by researchers because of its stability, specificity and because of its low interference with the overall function of the targeted molecule. GoldBio’s selection of exceptional biotin products are offered at a lower price, allowing you to make the most of your research.

Biotin‐PEG4‐NHS Ester

Catalog ID Size Pricing
B-720-25 25 mg $ 98.00
B-720-100 100 mg $ 201.00

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.
