NHS-SS-PEG3-Biotin is a amine reactive biotinylation reagent that labels antibodies and other proteins and molecules that contain primary amines. NHS-SS-PEG3-Biotin reacts efficiently with pirmary amino groups in alkaline buffers to form stable amide bonds. The disulfide bond in the spacer arm is also cleavable using reducing agents such as TCEP and DTT. The PEG spacer provides solubility and flexibility to the molecule, allowing for enhanced accessibility to the target molecules. It is a valuable tool for researchers in the fields of chemical biology, drug discovery, and biomedical engineering.
