Le Fa'ailoga Fa'avasega: Aisea e le manuia ai pepa sikoa fa'apisinisi mo fa'asologa lavelave
Ole tele o fa'avasegaga fa'atau oloa e iloilo tagata fa'atau e fai ma fa'asalalauga fa'amaumauga nai lo pa'aga fa'apitoa kemisi. E mafai e se tagata fa'atau oloa ona maua fa'ailoga maualuga mo felauaiga 5,000 peptides laina masani i lalo o le lima aso ae o loʻo tumau pea le le mafai ona faʻapipiʻiina se faʻasologa 40-mer o loʻo i ai ni matasele disulfide e tolu., o se filifili pito lysyl PEGylated, ma se vaega N-terminal palmitoyl.
Fa'asologa otometi fa'ameamea fa'atutu-vaega peptide (SPSS) e malepe tulafono pe a feagai ma faigata, fa'asologa e le fa'a-canonical. A'o fa'atuputeleina le umi ole peptide po'o le toe fa'atupuina ole vaega ole hydrophobic, fa'atasiga va'ava'ai ma le fa'avaeina o le beta-pepa i le taimi o le fa'apotopotoina o filifili fa'aosoina fa'alavelave fa'alavelave fa'atasi.. I lalo o tulaga otometi taamilomilo, e i'u ai i le tele o mea leaga o le tipiina ma le le atoatoa o le tapeina e toetoe a le mafai ona tu'ueseese i lalo.
Key Takeaway: Lisi fa'atau pisinisi fa'avasega le saoasaoa o le suiga ma le tau mo peptide laina faigofie. O fa'asologa lavelave e mana'omia lemu, ta'amilosaga so'o fa'atasi, faʻapipiʻiina resini uta, ma kemisi fa'apitoa cleavage e pa'ū atoa i fafo atu o ta'iala fa'avasega.
E lē gata i lea, fa'ata'ita'iga fa'apapa'u fa'aa'oa'oga fa'atau atu e fa'alagolago i le koluma e tasi Fa'aliliuina-Vaega High-Performance Liquid Chromatography (RP-HPLC) mo talosaga mama. O se tagata fa'atau fa'asalalauga "98% mama" e fa'aaoga ai se fa'alili ole C18 fa'asolo e tasi e mafai ona fa'apipi'i fa'atasi le stereoisomers., tapeina vaega, po'o fa'apotopotoga solu. O le su'esu'eina o le taua moni e mana'omia ai le su'esu'eina pe fa'afefea ona taulimaina e le tagata fa'atau suiga lavelave o vaila'au, fa'amaoniga fa'apitoa, ma le fa'amama le gaosiga.
