In Andromeda Strain, what is one experiment the scientists set up at Wildfire to try to gather information?

The scientists at Wildfire conduct many experiments to try to find out what the deadly organism is and how it works. Their goal is to devise a way to counteract and destroy it. In chapter 16, when they discover that the organism causes blood to clot and solidify, which results in death, Burton decides to run a test to determine whether preventing the blood from clotting would prevent death. So he injects some laboratory rats with Heparin, an anticoagulant drug, and exposes them to the organism. The rat that receives a small dose of Heparin dies almost immediately, and one injected with a large amount dies shortly afterward. The experiment fails, but the scientists have gathered the information that the anticoagulants have no effect on the organism.
