DSPE-PEG-Biotin is a phospholipid conjugate consisting of three distinct functional groups: DSPE, PEG, and biotin. DSPE, or 1,2-distearoyl-sn-glycero-3-phosphoethanolamine, is a phospholipid commonly found in cell membranes that confers biocompatibility and stability to the molecule. PEG, or polyethylene glycol, is a water-soluble polymer that enhances the solubility, pharmacokinetics, and immunogenicity of the conjugate. Biotin, also known as vitamin H or B7, is a small molecule that binds specifically to streptavidin, a protein commonly used in biological assays for protein detection and isolation.

DSPE-PEG-Biotin is widely used in pharmaceutical research and development due to its unique properties and versatile applications. It can be used as a drug delivery vehicle to encapsulate and target therapeutic agents to specific cells or tissues, as well as a imaging agent to visualize biological processes in vivo. In addition, DSPE-PEG-Biotin is commonly used in the development of diagnostic assays for the detection and quantification of biomolecules, such as proteins, nucleic acids, and carbohydrates. Its biotin moiety allows for easy immobilization onto streptavidin-coated surfaces, enabling sensitive and specific detection of target molecules.
