FAQ

Dab tsi yog qhov txwv ntawm qhov ntev ntawm hluavtaws peptides?

Lub polypeptide synthesized los ntawm peb lub tuam txhab yog 6 ~ 50 amino acids nyob rau hauv ntev.Cov txheej txheem txheej txheej txheej txheej txheej txheej txheej feem ntau tsim peptides ntawm 6 txog 50 amino acids.

Yuav piav qhia P+Na thiab P+K peaks hauv MALDI(MS) li cas?

Peaks Na thiab K feem ntau pom hauv MALDI, thiab sodium thiab potassium los ntawm cov dej hnyav.Txawm tias cov dej distilled thiab deionized tuaj yeem muaj cov lej ntawm sodium thiab potassium ions uas tsis tuaj yeem tshem tawm tag nrho.Lawv kuj ionize thiab khi rau cov dawb carboxyl pawg ntawm peptide thaum lub sij hawm loj spectrometry.Vim tias tsis muaj kev ua kom huv huv kom tshem tawm sodium thiab potassium ions los ntawm dej, nws yog qee zaum inevitable uas sodium thiab potassium peaks tshwm sim hauv MALDI MS daim ntawv qhia.

Thov piav qhia koj lub tswv yim ua kom huv

Cov peptides tsim los ntawm peb lub tuam txhab tau ua kom huv los ntawm kev npaj rov qab-theem HPLC nrog TFA thiab pH 2 ntxiv rau ob theem mobile.Theem A yog 0.1% TFA hauv dej ntshiab, thiab theem B yog 0.1% TFA hauv ACN, pH 2. Cov qauv tuaj yeem yaj ncaj qha rau theem A, lossis yaj hauv A me me ntawm B theem thiab diluted nrog A theem.Qee lub sij hawm nws yuav tsim nyog rau yaj hydrophobic peptides nrog cov kuab tshuaj muaj zog xws li formic acid lossis acetic acid, nyob ntawm seb qhov sib lawv liag ntawm peptide.Ntawm pH 6.8, feem ntau nyuaj rau yaj thiab ntxuav cov peptide, yog li peb feem ntau yaj peptide ua ntej thiab tom qab ntawd siv ob theem mobile rau gradient elution.Cov tshuaj tsis haum ntawm pH 6.8 yog 10 mM ammonium acetate hauv dej ntshiab ultra (mobile theem A), ntshiab ACN (mobile theem B).Cov khoom sib txawv tau sau thiab txheeb xyuas los ntawm MADLI-TOF MS.Purity tau txheeb xyuas los ntawm kev hloov pauv-theem HPLC.Tom qab ntawd, lub hom phiaj peptides tau lyophilized, thiab cov lyophilized peptides tau muab tso ua ke rau hauv me me vials.

Koj saib xyuas koj cov khoom li cas?

Tag nrho cov peptides hluavtaws tau soj ntsuam los ntawm HPLC thiab MS, tshwj tsis yog MALDIMS.Txij li thaum peptides yog ionized nyob rau hauv lawv tus kheej ib theem zuj zus nyob rau hauv sib txawv loj spectrometers, HPLC-MS cov tswv yim yuav siv tau los soj ntsuam cov peaks ntawm ionization hauv HPLC.Peb cov cuab yeej siv txuj ci [MALDI-MS, HPLC-(ESI)MS (ion ntxiab thiab tetrode array)] muab kev ruaj ntseg rau kev tsom xam.

Puas yog qhov solubility ntawm peptide cuam tshuam nrog qhov zoo ntawm peptide?

Cov peptides hluavtaws tsis yaj zoo, cov peptides muaj teeb meem, txoj cai?

A: Nws yog ib qho nyuaj rau kwv yees raws nraim li cas soluble peptide yog thiab qhov hnyav npaum li cas yog.Nws tsis yog qhov tseeb tias muaj teeb meem nrog peptide synthesis yog tias nws nyuaj rau yaj.

Koj khaws peptides hauv kev daws li cas?

Yog tias koj yuav tsum khaws koj cov peptides hauv cov kua, siv cov tshuaj tsis huv ntawm PH 5-6 thiab khaws cia ntawm -20℃txhawm rau txuas lub neej ntawm koj cov peptides hauv kev daws teeb meem.

Ntev npaum li cas peptides nyob hauv kev daws?

Nws yog qhov zoo tshaj kom tsis txhob khaws cov peptides seem hauv cov tshuaj.Lub txee lub neej ntawm polypeptides nyob rau hauv kev daws yog txwv heev, tshwj xeeb tshaj yog cov neeg uas muaj cysteine, methionine, tryptophan, asparagic acid, glutamic acid, thiab N-terminal glutamic acid nyob rau hauv ib theem zuj zus.Nyob rau hauv dav dav, tshem tawm qhov tsim nyog tus nqi ntawm kev siv, tus so ntawm lub freeze qhuav rau lub sij hawm ntev cia.
