This is a rapid and reversible staining used for locating protein bands on Western blots and comparing protein band intensity. It produces reddish-pink-stained bands on membranes, which is useful because it does not have a deleterious effect on the property of proteins. It is also commonly used as a method for locating polypeptides 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 membranes.
