r******k 发帖数: 446 | 1 最近小弟要测PI(3,4)P2的含量,但是如何normalize呢? cell number? 还是PI(
3,4)P2 / PIP3的比值?,我有点晕了。。。 大神们求助。 | C*********h 发帖数: 83 | 2 mass spec
用total ion去normalize

| p*****h 发帖数: 36 | 3 current LC-MS does not separate PI34P2 from PI45P2, the latter being much
more abundant.
3-H Inositol labeling, lipid extraction, deacylation, and anion-exchange
HPLC is the way to go. (you may try to find a collaborator).

i can separate PI(3,4)P2 with a kit .
