We like all of your designs as they take into account an upstream and downstream process, double rainbow, and some DNA. On #38, can you put the 3 circles again at the end of the Logo after "vec"? This shows upstream making protein before the "P" and downstream purifying after the "C". Then you may have a way to connect the two circles with wording like in #72 or a swoosh/rainbow type image. Can you play with different colors in #38 and the swooshes in #28. We are not locked in on blue and green especially for the rainbow type image and DNA representations. thanks
