Instructions
I. Solution preparation
1. Preparation of mother solution and working solution: It can be dissolved in DMSO and further diluted to aqueous buffer solution as working solution in the experiment.
II. Operation steps
1. Sample preparation
Target molecule: This probe is mainly used to detect MIF activity, or as a general fluorescent dye. It can be used to study the role of MIF in inflammation, cancer and immune response.
Concentration: For fluorescence experiments, a solution with a concentration of 1–10 μM is usually used, and the specific concentration is adjusted according to the sensitivity and requirements of the experiment.
2. Experimental conditions
1) Buffer selection: In order to study MIF inhibition, it is recommended to select a suitable buffer (such as phosphate buffer with a pH range of 7.0–7.5) to simulate physiological conditions.
2) Add 3-Cyano-7-hydroxycoumarin: Add an appropriate amount of 3-Cyano-7-hydroxycoumarin solution (usually 0.1–1 mM) to the sample.
3) Reaction temperature and time: Typically, the reaction temperature is room temperature to 37°C. The reaction time depends on the activity of the enzyme in the sample and is usually between 30 minutes and 1 hour.
4) Hydrogen peroxide (H₂O₂) is usually added as an oxidant to initiate the reaction.
5) Color change: After the reaction is completed, the product is usually brown or dark in color and can be quantitatively detected using colorimetric methods (such as UV-Vis spectrophotometer).
3. Fluorescence imaging
3-Cyano-7-hydroxycoumarin can be used as a fluorescent probe to track molecular interactions or the activity of biomolecules such as MIF in live cell imaging.
Detection: Fluorescence intensity is quantified by fluorescence microplate reader, confocal microscopy or flow cytometry.
4. Inhibition assay
For MIF tautomerase inhibition assay, 3-Cyano-7-hydroxycoumarin can be used to determine its inhibitory potency with a Ki value of 2.9 μM.
Methods: The inhibition of MIF by 3-Cyano-7-hydroxycoumarin was evaluated by measuring the fluorescence quenching effect.
Storage conditions
1) 3-Cyano-7-hydroxycoumarin should be stored in a dry, cool place at -20°C, away from light and moisture.
2) The solution should be freshly prepared and, if storage is required, should be stored at -20°C or below and away from light.

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
