Yonke imikhiqizo yenkampani isetshenziselwa inhloso yocwaningo lwesayensi kuphela, yona'kwenqatshelwe ukusetshenziswa ngokuqondile yinoma yimuphi umuntu emzimbeni womuntu.

FAQ

Yimiphi imikhawulo ngobude bama-peptide okwenziwa?

I-polypeptide ehlanganiswe yinkampani yethu ingama-amino acid ayi-6 ~ 50 ubude.Izinqubo ezijwayelekile zokuhlanganisa isigaba esiqinile ngokuvamile zikhiqiza ama-peptide angu-6 kuye kwangama-50 amino acid.

Zichazwa kanjani iziqongo ze-P+Na ne-P+K ku-MALDI(MS)?

Iziqongo i-Na ne-K zivame ukubonakala eMALDI, kanti i-sodium ne-potassium ziphuma emanzini ancibilikayo.Ngisho namanzi acwengekile nahlanganisiwe angaqukatha amanani e-sodium ne-potassium ion angakwazi ukususwa ngokuphelele.Futhi zi-ionize futhi zibophe eqenjini le-carboxyl lamahhala le-peptide ngesikhathi se-mass spectrometry.Ngenxa yokuthi alukho uhlelo lokuhlanza lokususa ama-ion e-sodium ne-potassium emanzini, kwesinye isikhathi akunakugwemeka ukuthi iziqongo zesodium ne-potassium zivele kumephu ye-MALDI MS.

Sicela uchaze isu lakho lokuhlanza

Ama-peptide ahlanganiswe yinkampani yethu ahlanzwa nge-HPLC yesigaba esihlehlisiwe esine-TFA ne-pH 2 yengezwe kuzo zombili izigaba zamaselula.Isigaba A singu-0.1% TFA emanzini ahlanzekile kakhulu, futhi isigaba B singu-0.1% TFA ku-ACN, i-pH 2. Isampula ingancibilika ngokuqondile esigabeni A, noma incibilike ku-A inani elincane lesigaba B futhi ihlanjululwe ngesigaba esingu-A.Ngezinye izikhathi kungase kudingeke ukuncibilikisa ama-peptide e-hydrophobic ngezincibilikisi ezinamandla njenge-formic acid noma i-acetic acid, kuye ngokulandelana kwe-peptide.Ku-pH 6.8, ngokuvamile kunzima ukuncibilikisa kanye nokuhlanza i-peptide, ngakho-ke sivamise ukuncibilikisa i-peptide kuqala bese sisebenzisa izigaba ezimbili zamaselula ukuze sithole i-gradient.Isixazululo sebhafa ku-pH 6.8 sasingu-10 mM ammonium acetate emanzini ahlanzekile kakhulu (isigaba seselula A), i-ACN ehlanzekile (isigaba B seselula).Izingxenye ezihlukene zaqoqwa futhi zahlonzwa yi-MADLI-TOF MS.Ubumsulwa buhlaziywe yi-HPLC yesigaba esibuyiselwe emuva.Khona-ke, ama-peptide okuhlosiwe ayenziwe nge-lyophilized, futhi ama-peptide a-lyophilized ahlanganiswa abe izitsha ezincane.

Uyiqapha kanjani imikhiqizo yakho?

Wonke ama-peptide okwenziwa ahlaziywa yi-HPLC ne-MS, ngaphandle kwe-MALDIMS.Njengoba ama-peptide enziwe i-ionized ngokulandelana kwawo kuma-spectrometer amaningi ahlukene, amasu e-HPLC-MS angasetshenziswa ukuhlaziya lezo ziqongo ze-ionization ku-HPLC.Imishini yethu yobuchwepheshe [MALDI-MS, HPLC-(ESI)MS (ion trap and tetrode array)] inikeza isiqinisekiso esinokwethenjelwa sokuhlaziya.

Ingabe ukunyibilika kwe-peptide kuhlobene nekhwalithi ye-peptide?

Ama-peptides okwenziwa awancibiliki kahle, ama-peptides anenkinga, akunjalo?

IMP: Kunzima ukubikezela kahle ukuthi i-peptide inyibilika kanjani nokuthi siyini isincibilikisi esifanele.Akulona iqiniso ukuthi kunenkinga nge-peptide synthesis uma kunzima ukuyihlakaza.

Uwagcina kanjani ama-peptides kusisombululo?

Uma kufanele ugcine ama-peptide akho oketshezini, sebenzisa isigcina magciwane ku-PH 5-6 futhi ugcine ku- -20℃ukunweba impilo yama-peptide akho esixazululo.

Ngabe ama-peptide ahlala isikhathi esingakanani esixazululo?

Kungcono ukungagcini ama-peptide asele esixazululweni.Impilo yeshalofu ye-polypeptides esixazululweni ilinganiselwe kakhulu, ikakhulukazi lezo ezine-cysteine, i-methionine, i-tryptophan, i-asparagic acid, i-glutamic acid, ne-N-terminal glutamic acid ngokulandelana.Ngokuvamile, khipha inani elidingekayo lokusetshenziswa, lonke iqhwa lomisiwe ukuze ligcinwe isikhathi eside.
