A novel chimeric monoclonal antibody (Nocatmab) has been developed for the treatment of tetanospasmin toxicity, one of the most potent and dangerous toxins known in modern medicine. Each molecule of Nocatmab inactivates four molecules of tetanospasmin. Knowing that the lethal dose for tetanospasmin is 2.5 ng/kg for a human adult, and that the MW (Molecular Weight) of tetanospasmin is 150,020 amu, can you calculate the minimal dose of Nocatmab (MW 348,055 amu) required to treat a subject who weighs 63 kg and has recieved a lethal dose of tetanospasmin?
