$NAUT According to my understanding, There's a substantial difference between mass spectroscopy and iterative mapping. Parag Mallick said that they're not trying to challenge this tech but Nautilus is trying to deliver something complementary. Mass spectroscopy only asks 1 question at a time in bulk while Iterative Mapping gets to ask hundreds of them in parallel. It's close to playing the game Guess Who? You might ask ''who are you?'' as the most direct approach but asking far-reaching questions such as ''are you wearing a black t-shirt or glasses?'' and hundreds of them more in parallel gives you a lot more precision when it comes to less abundant proteoforms. Furthermore, what other players do is quite a linear approach in my opinion. They're trying to measure them on a very tiny piece (~1 nanometer) while they go to opposite direction cleverly. Nautilus combines molecules, binds them to measure with a lot more efficiency. This bioorthogonal approach (Nobel-prized click chemistry) comes from Carolyn R. Bertozzie, it's like attaching LEGO puzzles together in advance to measure. In plain English, $NAUT seems to have a really differentiated platform unlike examining them in bulk or a linear approach. It would be wrong to take the easy way out spamming the ticker... I'll continue studying the tech and Q3.
