MARKING DYES

In the late 1970s, lab technicians were just beginning to explore the application we now call MOHS, a technique for orienting excised tissue from tumors with the aid of tissue marking dye. At that time, formal medical dyes that provided good adherence through processing were not available. Dr. Terence Davidson (UCSD) and Bradley Products, Inc. worked together to develop a collection of tissue marking dyes in different colors. After testing hundreds of products, materials of high quality were identified and the original full complement of five medical marking dye colors - green, yellow, black, red and blue - were developed. In 1984, these became known as The Davidson Marking System®. Later, orange and violet dyes were added and more recently, lime was added making a full complement of eight colors of margin marking dye. We continue to optimize these dyes as well as search for additional colors... We are proud to say that, today, all top 20 hospitals, as named by US News & World Report..
