|Solvent:||DMSO, Pyridine, Methanol, Ethanol, etc.|
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|Study on the interaction between catharanthine tartrate and DNA by spectrometric method[Reference: WebLink]|
|The interaction of Catharanthine Tartrate and DNA was studied using UV spectrometry,fluorescence spectrometry and fluorescent probe.The results showed that the fluorescence intensity of Catharanthine Tartrate was quenched in the presence of DNA,and this mechanism was judged as static quenching.The binding constant K at 25℃ and 40℃ were calculated as 5.38×104 and 5.85×102,and the binding sites number n as 1.405 and 0.8306.According to the binding constant K at 25℃ and 40℃,the thermodynamic parameters of the reaction of Catharanthine Tartrate and DNA were calculated as follows: ΔHm=-233.77 kJ·mol-1,ΔGm(298 K)=-27.0 kJ·mol-1,ΔSm(298 K)=-693.8 J·K-1·mol-1,and the main binding force between Catharanthine Tartrate and DNA is hydrogen bonding or van der Waals force according to thermodynamic parameters.The UV spectrometry test showed that as the DNA concentration increased,the blue shift of the absorbance peak occured and the absorbance decreased significantly,the results of fluorescence probe test further proved that Catharanthine Tartrate binds with DNA in a mode of groove binding.|

|Study on the Effect of Se(Ⅳ) on the Interaction Between Catharanthine Tartrate and DNA[Reference: WebLink]|
|The effect of Se(Ⅳ)on the interaction between Catharanthine Tartrate and DNA was studied by fluorescence spectrometry, UV spectroscopy and viscosity method. The results showed that the addition of Se(Ⅳ)changed the main binding force of Catharanthine Tartrate and DNA from hydrogen bond and van der Waals force into electrostatic force, and the binding mode from groove binding into electrostatic binding. The change of binding constant and the UV spectroscopy results showed that Se(Ⅳ)can inhibit the binding of Catharanthine Tartrate and DNA.|
