FAQ：

Kodi ma peptides okhala ndi cys amachepetsedwa?

Ngati peptide sanapezeke kukhala oxidized, sitikuchepetsa ma cys. Onse a polypeptides onse amapezeka kuchokera ku mtundu wopanda pake kuyeretsedwa ndi lyophilized pansi pa PH2, zomwe mwina mwina zimalepheretsa ma okosi a CYJ. Peptides okhala ndi ziphuphu zimayeretsedwa ku Ph2 pokhapokha ngati pali chifukwa china choyeretsera pa Ph6.8. Ngati kuyeretsa kumachitika pa Ph6.8, chinthu choyeretsedwa kuyenera kuthandizidwa ndi acidi nthawi yomweyo kupewa maxianation. Mu gawo lomaliza lolamulira, chifukwa cha ma cys, ngati kukhalapo kwa zolemera za madokotala (2p + h) pamapu a MS, zikuwonetsa kuti kuchepa kwapangidwa. Ngati palibe vuto ndi ms ndi hplc, tidzapereka mwachindunji ndi kutumiza katunduyo popanda kukonzanso kwina. Tiyenera kudziwa kuti peptides okhala ndi ma cys oxidation osakhalitsa nthawi yayitali, ndipo kuchuluka kwa makutidwe ndi peptide motsatizana ndi malo osungira.

Kodi ndi zosintha ziti zomwe zidasinthidwa polypeption zitha kuphatikizidwa ku China peptide?

Kampani yathu imapereka malo osiyanasiyana osinthika, monga acetylation, biossin, phosphorylation Kusinthana, kusintha kwa flurescence kusinthidwa, kungathenso kusinthidwa malinga ndi zosowa zanu zapadera.

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.

Kodi Peptides ndi chiyani?

Peptides ndifupi Mamolekyu amatekcules opangidwa ndi amino acid omwe amalumikizidwa pamodzi ndi zokambirana za Peptide. Nthawi zambiri amakhala ndi 2 mpaka 70 amino acid.
