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 kulemera ndi chiyani? Kodi Peptide ndi chiyani?

Lophilided peptide nthawi zambiri imakhala yofananira komanso yofananira, itha kukhalabe ndi madzi okwanira, ma sosorbded ndi mchere chifukwa cha mawonekedwe a chipinda chomwecho. Izi sizitanthauza kuti kuyera kwa peptide sikokwanira, koma zomwe zomwe zimapezeka pa peptide zimachepetsedwa ndi 10% mpaka 30%. Kulemera kwa peptide ndi kulemera kwenikweni kwa peptide minuyi madzi ndi masitepe a masitepe. Pofuna kuonetsetsa kuti peptide, zinthu zomwe sizikufuna zilonda zimayenera kuchotsedwa ku poppa peptide.

Chani Kodi Ubwino wa Pep-Osinthidwa?
Kusintha kwa polyethylene glycol ndikuwonjezera polymer (ethylene glycol) ku molekyulu ya chandamale pogwiritsa ntchito molema. Mwa kubisa peptirira, kusintha kwa peg kumapusitsa chitetezo cha mthupi cha foni, kumawonjezera achire zotsatira za peputides, ndikuwonjezera kusungunuka ndi bioavailabic mankhwala osokoneza bongo. Itha kuwonjezera nthawi yozungulira ya polypeptides pochepetsa chilolezo.

Ndikufuna peptide wa cyclica, yomwe ili ndi tryptophan, kodi idzakhala oxidid?

Makutidwenation a tryptophan ndi chinthu wamba ku Peptide makutidwe, ndipo ma peptides nthawi zambiri amasambira musanayeretsedwe. Ngati makutidwe otsatsa a tryptophan amapezeka, nthawi yosungayisa ya peputiyi pa HPLC Column isintha, ndipo makutidwewo amatha kuchotsedwa ndikuyeretsa. Kuphatikiza apo, ma peptiddid amapezekanso amatha kupezekanso ndi ms.

Kodi peptide yanga imanyamulidwa bwanji? Kodi malipoti oyesa amaperekedwa ndi ati?

Ma polypeptives onse owuma nthawi zambiri amasungidwa muzovala zapadera za 2 ml kapena 10ml malipoti omwe ali ndi zidziwitso zokhala ndi chidziwitso chotsatira, zoyera, zoyera, ndi ma nuMber wa Polypeptide.
