Novokinin othandizira / 35873-77-9 / peptide kuyeretsa

Novokinin ndi nsanja yomwe imagwira ngati angiotensin at2 Agonist Agonist, opangidwa ndi Amino Acid, ndipo makamaka amamanga ku Angiotensin At2 Receptin. Novokinin amawonetsa zochitika za vasodilatory ndi antihypertensive poyambitsa IP (Prostationclin) zolandila, ndipo zimalepheretsa kudya chakudya poyambitsa PGE2-EP4.

FAQ：

Ngati mukufuna kusinthidwa kwa biotin ku n crumnal, muyenera kuyika kusiyana pakati pa biotin ndi peptide motsatizana?

Njira ya Biotin yolembedwa ndi kampani yathu ndikuphatikiza ahx ku Trupdite unyolo, wotsatiridwa ndi biotin. AHX ndi 6-kaboni pazinthu za mpweya zomwe zimalepheretsa peptide ndi biotin.

Kodi pali kusiyana kotani pakati pa ma peptides ndi mapuloteni?

Peptides ndi mapuloteni ali opangidwa ndi amino acid, koma amasiyana mumalenjemedwe ndi kutalika. Nthawi zambiri, olemera olemera osakwana 10,000 (da) ndi zazifupi amino acin amatchedwa ma unyolo olemera kwambiri komanso olemera kwambiri amatchulidwa ngati mapuloteni.

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.

Chifukwa chiyani ma peptides ayenera kusinthidwa ndi acetylated acetylated ndi ma tedidal?
Zosintha zoterezi zimatha kupatsa ndalama zowerengera zomwe zili zachikhalidwe.

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℃ kusungidwa 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 pa zofooka za acidic ndi sitolo ku -20℃.
