FAQ
Ndezvipi zvinogumira pakureba kwesynthetic peptides?
Iyo polypeptide yakagadzirwa nekambani yedu ndeye 6 ~ 50 amino acids pakureba.Standard solid-phase synthesis maitiro anowanzo gadzira peptides ye6 kusvika 50 amino acids.
Nzira yekutsanangura sei nhongonya dzeP+Na neP+K muMALDI(MS)?
Peaks Na uye K inowanzoonekwa muMALDI, uye sodium nepotassium zvinobva mumvura inonyungudutsa.Kunyange mvura yakasvibiswa uye yakasvibiswa inogona kuva nehuwandu hwe sodium uye potassium ions isingagoni kubviswa zvachose.Ivo zvakare ionize uye vanosunga kune yemahara carboxyl boka re peptide panguva yehukuru spectrometry.Nekuti hapana hurongwa hwekuchenesa hwekubvisa sodium ne potassium ions kubva mumvura, dzimwe nguva hazvidzivisike kuti sodium uye potassium peaks dzinoonekwa muMALDI MS mepu.

Iwo mapeptides akagadzirwa nekambani yedu akacheneswa negadziriro yakadzoserwa-chikamu HPLC ine TFA uye pH 2 yakawedzerwa kune ese nhare nhanho.Phase A ndeye 0.1% TFA mumvura ye-ultra-pure, uye chikamu B ndeye 0.1% TFA mu ACN, pH 2. Muenzaniso unogona kunyungudutswa zvakananga muA phase, kana kuti yakanyungudutswa muA zvishoma B chikamu uye yakasvibiswa neA phase.Dzimwe nguva zvingave zvakakosha kunyungudutsa hydrophobic peptides ine zvinonyungudutsa zvakasimba zvakadai sefomic acid kana acetic acid, zvichienderana nekutevedzana kwepeptide.Pa pH 6.8, zvinogara zvakaoma kunyungudutsa uye kuchenesa peptide, saka isu tinowanzo nyungudutsa peptide kutanga tozoshandisa nhanho mbiri dzenhare yegradient elution.Mushonga webuffer papH 6.8 waiva 10 mM ammonium acetate mumvura yakanyanya-pure (mobile phase A), pure ACN (mobile phase B).Zvikamu zvakasiyana zvakaunganidzwa uye zvakaonekwa neMADLI-TOF MS.Kuchena kwakaongororwa neyakadzoserwa-chikamu HPLC.Zvadaro, peptides yaitariswa yakaitwa lyophilized, uye iyo lyophilized peptides yakasanganiswa kuita mabhodhoro madiki.
Iwe unotarisa sei zvigadzirwa zvako?
Ese mapeptides ekugadzira akaongororwa neHPLC neMS, kunze kweMALDIMS.Sezvo mapeptide akaiswa ionized mumiteedzero yawo mune akasiyana misa spectrometer, HPLC-MS matekiniki anogona kushandiswa kuongorora iwo epamusoro eionization muHPLC.Midziyo yedu yehunyanzvi [MALDI-MS, HPLC-(ESI)MS (ion trap uye tetrode array)] inopa vimbiso yakavimbika yekuongorora.
Iko kunyungudika kwepeptide kune hukama nemhando yepeptide?
Mapeptides ekugadzira haanyungudika zvakanaka, mapeptides ane dambudziko, handiti?
A: Zvakaoma kufanotaura chaizvo kuti peptide inonyungudika sei uye kuti chinonyungudutsa chakakodzera chii.Haisi chokwadi kuti pane dambudziko ne peptide synthesis kana yakaoma kunyungudika.
Iwe unochengetedza sei peptides mune mhinduro?
Kana uchifanira kuchengeta mapeptides ako mumvura, shandisa sterilized buffer paPH 5-6 wochengeta pa -20.℃kuwedzera hupenyu hwepeptides yako mumhinduro.
Mapeptides anogara kwenguva yakareba sei mukugadziriswa?
Zvakanakisa kusachengeta peptides yakasara mumhinduro.Sherufu yehupenyu hwepolypeptides mumhinduro ishoma, kunyanya avo vane cysteine, methionine, tryptophan, asparagic acid, glutamic acid, uye N-terminal glutamic acid mukutevedzana.Kazhinji, tora iyo inodiwa huwandu hwekushandisa, iyo yakasara yechando yakaomeswa kuchengetedza kwenguva refu.
