Needs more

Layout is good but it needs much more components to make it useable and worth it.

Search PubChem

Grazie per questo aggiornamento di oggi 4 agosto 2020, ma come mai non sono presenti gli anticorpi monoclonali? (Trastuzumab, Omalizumab, Alemtuzumab, etc....)? Ho provato diverse volte a cercarli, ma non li trova. Potete rilasciare un aggiornamento per inserire anche questa importantissima classe di farmaci? Grazie mille e buon lavoro!
