    Sensitivity of DPP and Pesotrader

    The sensitivity of the DPP device will be a big winner in the future. We developed a test in 2008 using the DPP format that was more sensitive than the Luminex testing format. The reason is that Luminex counts the antibody reacting-antigen covered beads at random as they pass through an narrow orifice to reach a mathematical threshold, whereas DPP captures the antibody on a line of antigen that simply shows up as a line that gets more and more pink. That line is a two (actually three) dimensional geometric shape that can be easily detected by enhanced vision or a light sensing device. If CEMI gets their own proprietary antigens and antibodies, that profit margin is going to quadruple with each test they manufacture. I am hoping that they look at environmental microbes and contaminants in the future. Lots of opportunity there.

    As for Peso, he/she was #$%$ off at Larry 4 years ago and not much has changed. In the meantime, CEMI has slowly gone up and achieved its milestones.

    Sentiment: Strong Buy
