Grade Biotechnology grade; highly pure; made with Type I ultrapure water (>18 MΩ·cm) and filtered through 0.22 µm

18:0 PEG2000 PE CF is a fluorescent lipid conjugate featuring a saturated 18-carbon phosphoethanolamine anchor tethered to a 2000 Da PEG chain ending in a carboxyfluorescein (CF) fluorophore. Presented as a fine powder (Catalog #B2017908), this amphiphilic molecule enables stable incorporation into lipid membranes—such as liposomes or micelle systems—facilitating bright, green-emitting fluorescence tagging in biochemical assays and imaging.

Constructed under stringent biotechnology-grade standards, 18:0 PEG2000 PE CF ensures batch-to-batch consistency and exceptional purity. Its long-chain lipid tail enhances membrane insertion, while the PEG spacer ensures stealth behavior and solubility. The carboxyfluorescein label allows sensitive detection with minimal autofluorescence, making it ideally suited for tracking membrane dynamics, receptor localization, or liposomal biodistribution in live-cell and in vitro platforms. Supplied in small quantities for precise applications with bulk ordering available for extended projects. Powder format and freezing at –20 °C contribute to long-term reagent stability.

Why researchers choose this product:

  • Combines membrane anchorage, PEG stabilization, and bright green fluorescence in one molecule
  • Supports high-contrast imaging with minimal background interference
  • Biotech-grade purity and consistent quality enhance experimental reproducibility
  • Powder form allows accurate dosing and extended shelf life
  • Bulk quantities available for sustained or large-scale studies

Indication for Use:
This product is for Research Use Only (RUO). It is not intended for diagnostic, therapeutic, or clinical use.
