A'o fa'atauina e le aufaipisinisi fa'aleaganu'u peptide e fai ma fa'amaumauga o oloa, fa'alavelave AI e mana'omia se pa'aga fa'apitoa CDMO fa'apipi'iina i tekonolosi fa'aopoopo, mua'i fa'amaopoopoina fa'aoga talafeagai, ma fa'atonuga lelei.
Pe a filifilia se paaga gaosiga mo faʻasologa faʻatulagaina AI, Iloiloga o tulaga gafatia-e pei o le avanoa i le tele o suʻega suʻega, potu mama mama, ma fetuutuuna'i fua-fa'aa'iga filifiliga - fa'amautinoaina o mamanu fa'akomepiuta e fa'asolosolo sologa lelei ile fa'amaoniaga fa'aletino.. R&D 'au o lo'o taumafai e fa'afeso'ota'i mamanu fa'atekinolosi ma fa'atinoina falesu'esu'e e mafai ona fa'afeso'ota'i tulaga fa'apitoa e pei o Suiga MOL mo 'au'aunaga tu'ufa'atasiga o le peptide ma su'esu'ega fa'apitoa fa'apitoa e fa'atatau i le tu'uina atu o le tu'uina atu o AI-to-bench.
Siakiga Fa'atino Fa'ainisinia: E iloilo lau fa'akomepiuta sui tauva fa'atatau ile synthesis fesible parameters, feutagai ma le MOL Changes technical team mo se iloiloga mae'ae'a a'o le'i fa'apipi'iina.
