Ponceau S, BS
Based on 1 Customer Validation
Both Ponceau S and Ponceau BS are synthetic dyes commonly used in biological research. They are commonly used as protein stains to visualize proteins in western blots and other protein detection analyses. Ponceau S is a red dye, while Ponceau BS is a blue shade of the same dye. Both dyes bind to positively charged amino acid residues in proteins for easy visualization. However, Ponceau S is more commonly used due to its higher sensitivity.

Solvent & Solubility
DMSO : 50 mg/mL (65.74 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 50 mg/mL (65.74 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
