FAQ：

Kodi mumasungunuka bwanji poizo?

Kusungunuka kwa polypeptide kumadalira makamaka kapangidwe kake, mtundu wa zilembo zosintha, mtundu wosinthika ndi ndende yomaliza. Ngati peptide ikapanda kuthekera m'madzi, ultrasound ingathandize kusungunuka. Chifukwa cha peptide woyambira, tikulimbikitsidwa kusungunuka ndi 10% acetic acid; Kwa acidic mapepu, kusungunuka ndi 10% nh4hco3 kumalimbikitsidwa. Ordic solt imathanso kuwonjezeredwanso kwa inlypeptions. Peptideyo imasungunuka pang'ono kuchepera (E.g., DMSO, DMF, isopropyl mowa, methanol, etc.). Ndikulimbikitsidwa kwambiri kuti peputiyi isungunuke mu solvel sorvent kenako kuwonjezeredwa pang'onopang'ono madzi kapena buffer ina mpaka chidwi chofuna.

Kodi mikhalidwe yabwino kwambiri yoteteza ndi iti? Kodi peptide imakhazikika bwanji?

Lyophilized, polypeptide imatha kupanga fluff kapena bondo, zomwe zingapewe kuwonongeka kwa polypeptide. Zoyenera Kusungirako: a. -20 ℃ yosungira kapena malo owuma b. Yesani kupewa kubwereza kwaulere. Yesani kupewa kusungidwa mu yankho (ufa wowuma ufa ungasungidwe m'matumba osiyana kuti mugwiritse ntchito) d. Ngati iyenera kusungidwa mu yankho, tikulimbikitsidwa kusungunula ma peptidel mu madzi osabala pansi pazinthu zofooka komanso sitolo pa -20 ℃.

Kodi peptide ndi chiyani?

Peptide ndi gawo lopangidwa ndi α-amino acid omwe amalumikizidwa ndi zomangira za peptide ndipo ndi gawo lapakatikati la mapuloteni hydrolysis. Pawiri yopangidwa ndi kukhazikika kwa ma amino acid mamolekyulu amatchedwa cupepture, komanso chimodzimodzi, penteptides, ma tepipturedes, ma tepiptures, ochulukirapo amatchedwa Polypeple.

Kodi katundu amanyamula bwanji?

Pa katundu wanu, tidzapereka DHL kapena makampani ena otumizira zinthu kuti azikutumizirani.
