Overview
Digitonin is a spirostan saponin obtained from the seeds and leaves of digitalis (D. purpurea, D. lanata). A mild nonionic detergent, digitonin is used in a wide range of applications, including solubilization of membrane proteins, permeabilization of cellular membranes, isolation of mitochondria and quantitation of cholesterol.
Water Solubility and Aqueous Solution Stability
The water solubility and aqueous solution stability of Digitonin (Water Soluble) were compared to that of a competitor’s equivalent product. Digitonin solutions (10 w/v%) were prepared at room temperature or at 60℃, and stored at 4℃ for 15 days, prior to optical density (600nm) measurements.

■Wako Digitonin lot no.: PTF7501
■Tested solubility: 10 w/v%
■Aqueous solution preparation procedure:
1. Room temperature, mixing for 5 minutes.
2. Incubation at 60℃ for 5 minutes.
■Aqueous solution storage temperature: 4℃.

Condition 1： Dissolved at Room temperature → Stored at 4℃ for 15 days ◆Wako Digitonin (Water Soluble) : Condition 2： Incubated at 60℃ for 5 minutes → Stored at 4℃ for 15days ◆Wako Digitonin (Water Soluble) : |
| Solubility and stability tests were performed on a 10 w/v% aqueous solution made from a typical lot of Digitonin. Note that 10 w/v% is much higher than the concentration adopted as quality criterion. Wako guarantees 4 w/v% solubility for every lot of Digitonin. |
