Minute™ Ponceau S Stain
This is a rapid and reversible staining for locating protein bands on Western blots and for comparing protein band intensity. It produces pink reddish stained bands on Western blot membranes. The stain is very useful because it does not have a deleterious effect on the property of proteins. It is also a common method for locating polypeptides on Western blots for protein sequencing. The stain binds to proteins on the membrane reversibly and works well for nitrocellulose and PVDF membranes. It is not recommended for positively charged membranes such as nylon membrane.
