我想进行胰岛细胞染色，参考凌启波老师的《实用组织病理技术》要使用到亮绿（light green），现在购买到的确实灿烂绿（Brilliant Green ），在网上找了些资料，发现两者分子式和分子量都不一样：
Brilliant Green (Certified Biological Stain), Fisher Chemical
  Brilliant Green
Certified Biological Stain
Application: For use in bacteriology in media.
Ethyl Green, Basic Green, Malachite Green G
C27H34N2O4S
F.W. 482.65
C.I. 42040
[633-03-4]
而，light green为：
Light Green SF yellowish

现在比较困惑，不知道这两者能否通用，请各位大侠指导一下，万分感谢！！
