摘要:
A lipid assay method, kit, and apparatus involving exposure of a protein, having a lipid recognition motif that interacts with a target lipid and a competing lipid, to a solution containing the competing lipid, and determining whether the target lipid is present in the solution. The target lipid has a stronger affinity to the lipid recognition motif than does the competing lipid. The lipid recognition motif is preferably a pleckstrin homology (PH) domain, with the target lipid being a phosphoinositide. The assay determines activity of a lipid kinase, the target lipid being a phosphorylation product of a reaction between the lipid kinase and a substrate lipid. The assay can be a cancer screening method for detection of cancer cells, where detection of certain levels of a PI(3,4,5)P3 target lipid is an indicator of a cancer cell.
摘要(中):
一种脂质测定方法,试剂盒和设备,涉及将含有与目标脂质和竞争性脂质相互作用的脂质识别基序的蛋白质暴露于含有竞争性脂质的溶液中,并确定目标脂质是否存在于溶液中 。 目标脂质比竞争性脂质对脂质识别基序具有更强的亲和力。 脂质识别基序优选为pleckstrin同源性(PH)结构域,靶脂质为磷酸肌醇。 该测定确定了脂质激酶的活性,该目标脂质是脂质激酶与底物脂质之间反应的磷酸化产物。 该测定可以是用于检测癌细胞的癌症筛选方法,其中检测到某些水平的PI(3,4,5)P3靶脂质是癌细胞的指标。
