A new drug is developed that targets and binds to the lipid A portion of LPS from Gram negative bacterial cells. This drug shows a high degree of activity and binding in a test tube setting against purified lipid A. Based on this information,

#Unit 2. Cellular Organization

We should fast track this drug and get it out to physicians immediately to help prevent toxic/septic shock in humans.
We should do some animal testing with whole Gram-negative cells and the drug before we jump to any conclusions.
We should next proceed by moving to testing in a test tube using whole Gram-negative cells to see if it binds with the same strength.
We should abandon the drug entirely binding to lipid A won't kill the bacteria, so the drug is useless to develop further
