Dansyl chloride (DNSCl)
(Synonyms: 丹磺酰氯; DNSCl) 目录号 : GC30318A reactive probe for derivatization of primary amines
Cas No.:605-65-2
Sample solution is provided at 25 µL, 10mM.
Dansyl chloride is a reactive probe for the derivatization of primary amines, including those on amino acids, peptides, and polyamines, for detection by HPLC.1,2,3 It has also been used for the derivatization of compounds containing phenol groups, such as steroids, for detection by MS/MS.4 Dansyl chloride is a fluorescent probe for proteins and enzymes.5 It displays excitation/emission maxima of 340/535 nm, respectively, in acetone.

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。
