Stellar Biotechnologies is sitting at the nexus of a new era of therapies and diagnostics driven by what I believe will be ever growing use of its key product, KLH, a potent, yet safe, molecule that can be used to both drive the immune system as well as assess the immune systems functional status. Because of the unique properties of KLH, an expanding number of researchers and scientists in academia, biotech and Pharma are finding novel and amazing uses for it. I believe an active SAB can enhance growth as well as help direct the board and executives to new markets and expanded use of this rare, naturally-sourced molecule and important medical reagent."
