过去对淋巴细胞的标记,多采用~(51)Cr、~(99m)Tc等,但由于这两种核素标记率低、溶出率高,~(99m)Tc的半衰期短,因而对研究淋巴细胞的免疫功能有很多缺点。~(111)In,因具有合适的光子能量(247和173KeV)和半衰期(2.8天),所以是现在临床核医学上使用率最高的放射性核素。曾有人报道,用~(111)In-8羟喹啉(~(111)In-Oxine)标记多种血球成份获得很高的标记率,几乎看不到被溶出。本文报道,为了解正常淋
In the past, lymphocytes were mostly labeled with ~ (51) Cr, ~ (99m) Tc, etc. However, due to the low labeling rate and high dissolution rate of these two radionuclides and the short half-life of 99m Tc, The immune function of cells has many disadvantages. ~ (111) In is now the most radically advanced nuclear nuclide in the world because of its suitable photon energies (247 and 173 KeV) and half-life (2.8 days). It has been reported, with ~ (111) In-8 hydroxyquinoline (~ (111) In-Oxine) labeled a variety of blood cell components to obtain a high labeling rate, almost no see was dissolved. This article reports that in order to understand normal showering
