General description
混合二甲苯是同分异构体二甲苯的混合物，包括邻位，间位和对位二甲苯。它的分散发射和质谱飞行时间已经被报道了。在100cm-1范围内，发现了S1 ↔ 向S0状态转化，并且这种转化因为环状甲基基团内部旋转而增加。使用时间分辨原位FTIR光谱和气相色谱分析，研究它的扩散系数，吸收率和HSZM-5表面的异构化效果。
Application
混合二甲苯可以用于氯霉素乙酞转移酶（CAT）分析，评估CAT基因表达。

Efficient and controllable expression of a transgene usually requires the presence of intron sequences and much efforts have been made to produce retrovirus vectors that can transduce and integrate genes with introns. However, this has proven difficult because the viral
