Other Notes
FSL-fluorescein is a KODE™ technology construct designed to label hydrophobic surfaces including living cells with biotin. All FSL constructs consist of three essential designable features:
• functional component (F)
• spacer (S)
• diacyl lipid (L) FSL-fluorescein is comprised of a fluorescein residue representing F, conjugated via a spacer (SA2) to an an activated adipate derivative of dioleoylphosphatidylethanolamine (L1).
Packaged as 1 mg FSL-Fluorescein with 0.42 mg sodium bicarbonate to improve solubility.
Legal Information
KODE Constructs are supplied by KODE Biotech Materials Limited under license from KODE Biotech Limited.
KODE is a trademark of KODE Biotech Ltd.
Application
All FSL constructs disperse in biocompatible media and spontaneously and stably incorporate into cell membranes. Cells modified with FSL constructs are known as kodecytes and usually maintain their normal vitality and functionality. FSL-fluorescein has been specifically designed to create fluorescein-labeled live cells (kodecytes) but can also be used to modify other hydrophobic surfaces including fixed cells, virions, and solid phase surfaces. Fluorescein-labeled kodecytes can be visualized at the approximate absorbance wavelength of 488 nm and emission at 518 nm.
