Ponceau S CAS:6226-79-5 Manufacturer Price

Ponceau S is a red dye commonly used to stain proteins on membranes in protein research. It is used to visualize the proteins after they have been transferred from a gel onto a membrane. The dye binds to the proteins and allows for easy visualization and analysis. Ponceau S staining is useful for assessing the transfer efficiency of proteins and for troubleshooting potential issues during the transfer process. It is a reversible stain, meaning that it does not permanently bind to the proteins, which allows for further analysis such as immunodetection or quantification.
