FSL Constructs Video Protocol

All FSL constructs disperse in biocompatible media and spontaneously and stably incorporate into cell membranes. Cells modified with KODE constructs are known as kodecytes and usually maintain their normal vitality and functionality.

FSL-GB3 has been specifically designed to create live cells (kodecytes) expressing GB3 antigens but can also be used to modify other hydrophobic surfaces including fixed cells, virions, and solid phase surfaces. This product has been used in vitro to inhibit HIV virions and bind to veratoxin.

Other Notes

FSL-GB3 is a KODE technology construct designed to label hydrophobic surfaces including living cells with blood group GB3 trisaccharide (also known as Pk). All KODE FSL constructs consist of three essential designable features: a functional component (F), a spacer (S), and a diacyl lipid (L). FSL-GB3 is comprised of the blood group GB3 (Pk) trisaccharide Galα4Galβ4Glcβ representing F, conjugated via an O(CH2)3NH spacer (SA1) to an activated adipate derivative of dioleoyl­phos­pha­tidyl­ethanolamine (L1).
