Product Information

Description	DSPE-PEG (2000) Biotin is a PEGylated phospholipid functionalized with biotin at the distal end of a 2000 Da polyethylene glycol chain, providing both hydrophilic stability and high-affinity recognition capability. Its integration into lipid bilayers creates biofunctional surfaces that can selectively bind streptavidin or avidin-linked molecules. This compound is commonly employed in constructing biosensors, affinity purification systems, and targeted lipid vesicles. The long PEG spacer improves biotin accessibility while maintaining bilayer integrity, ensuring consistent performance in surface chemistry and biointerfacing studies.
