Founded in 1990 by Sidney Pestka, M.D., PBL InterferonSource has become the premier supplier of reliable high-quality interferon products. We have grown each and every year since 1998, when we began direct sales to customers like you.
PBL started as a family business. Although we have grown substantially since that time, we have made it a point to retain the values that we grew up with: a single-minded focus on our scientific mission and business goals; and a particular concern for and commitment to each of our customers. We are also pleased to be able to support the mission of our "sister company" PBL Therapeutics, which is focused on developing interferon-based drugs to treat cancer.
PBL's goal has always been to facilitate the advancement of research. To that end, each year we aim to increase the quality and quantity of our products, to supplement our store of product information, and to provide scientists around the world with the support they require.
