Chromomycin A3 is an anthraquinone antibiotic and antitumor agent isolated from S. griseus that is used as a fluorescent probe for DNA with excitation/emission spectra of 445/575 nm.[1],[2] Its DNA binding is specific to two or more contiguous GC base pairs, which makes it suitable for characterizing heterochromatin in plants with species-specific AT:GC ratios.[2],[3] Chromomycin A3 is cytotoxic against non-small cell lung cancer and cervical cancer in vitro (IC50s = 1, 42, 60, and 40 nM for HCC44, A549, ME180, and HeLa cells, respectively).[4],[5] It also inhibits oxidative stress- and DNA damage-induced neuronal injury by enhancing Sp1 and Sp3 transcription factor binding.[6]

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
