Bifunctional lipid technology: Cells convert externally added photoactivatable and “clickable” fatty acids into a variety of bifunctional phospholipids that can be covalently linked to their protein‐binding partners by irradiation with UV light. Derivatization of the clickable group with a reporter molecule makes it possible to identify and image the lipid‐bound proteins in situ (see scheme).
双功能脂质技术:细胞将外部添加的可光活化和“可点击”的脂肪酸转化为多种双功能磷脂,这些双功能磷脂可以通过紫外线照射与它们的蛋白结合伴侣共价连接。用报道分子对可点击基团进行衍生化使得可以原位鉴定和成像脂质结合蛋白(参见方案)。
