FAQ:

Qhov kawg twg yog qhov zoo tshaj rau kuv qhov kev tshawb fawb?

Los ntawm lub neej ntawd, peptide xaus nrog N-terminal dawb amino pawg thiab C-terminal dawb carboxyl pawg.Cov kab mob peptide feem ntau sawv cev rau qib ntawm niam protein.Yuav kom nyob ze rau niam cov protein, qhov kawg ntawm peptide feem ntau yuav tsum tau kaw, uas yog, n-terminal acetylation thiab C-terminal amidation.Qhov kev hloov kho no zam kev qhia txog kev them nqi ntau dhau, thiab tseem ua rau nws muaj peev xwm tiv thaiv exonucliase kev ua, kom cov peptide ruaj khov dua.

Puas tau hloov kho cov ntawv sau npe polypeptides tuaj yeem ua rau hauv Suav peptide?

Peb lub tuam txhab muab ntau yam kev hloov pauv peptide labeling, xws li acetylation, biotin labeling, phosphorylation modification, fluorescence modification, kuj tuaj yeem kho raws li koj qhov kev xav tau tshwj xeeb.

Yuav ua li cas yaj polypeptides?

Lub solubility ntawm polypeptide yog nyob ntawm nws cov qauv thawj thiab theem nrab, qhov kev hloov kho daim ntawv lo, hnyav hom thiab qhov kawg concentration.Yog tias peptide yog insoluble hauv dej, ultrasound tuaj yeem pab yaj nws.Rau peptide yooj yim, nws raug nquahu kom yaj nrog 10% acetic acid;Rau acidic peptides, dissolution nrog 10% NH4HCO3 yog pom zoo.Organic cov kuab tshuaj kuj tuaj yeem ntxiv rau cov tshuaj tsis muaj kuab lom polypeptides.Cov peptide yog yaj hauv qhov tsawg kawg nkaus ntawm cov kuab tshuaj organic (xws li DMSO, DMF, isopropyl cawv, methanol, thiab lwm yam).Nws yog qhov pom zoo tias peptide yuav yaj hauv cov kuab tshuaj organic ua ntej thiab tom qab ntawd maj mam ntxiv rau hauv dej lossis lwm yam tsis tuaj yeem mus txog rau qhov xav tau concentration.

Dab tsi yog qhov kev khaws cia zoo tshaj plaws?Lub peptide ruaj khov npaum li cas?

Tom qab lyophilized, polypeptide tuaj yeem tsim fluff lossis flocculant hmoov, uas tuaj yeem zam kev degradation ntxov ntawm polypeptide.Pom zoo cia tej yam kev mob: a.-20℃cia lossis qhuav ib puag ncig b.Sim kom tsis txhob rov khov-thaw c.Sim kom tsis txhob cia hauv lub xeev daws teeb meem (cov hmoov qhuav qhuav tuaj yeem khaws cia rau hauv cov pob khoom sib cais kom yooj yim siv) d.Yog tias nws yuav tsum tau muab khaws cia rau hauv cov tshuaj, nws raug nquahu kom yaj cov peptides hauv dej tsis muaj menyuam nyob rau hauv cov dej tsis muaj zog acidic thiab khaws cia ntawm -20℃.

Kuv peptide thauj mus li cas?Cov ntaub ntawv xeem twg yog muab?

Tag nrho cov khov-qhuav polypeptides feem ntau yog khaws cia rau hauv cov thawv tshwj xeeb ntawm 2 ml lossis 10ml nrog cov ntaub ntawv txheeb xyuas thawj zaug thiab cov ntaub ntawv sib xyaw uas muaj cov ntaub ntawv tseem ceeb xws li ntu, qhov hnyav molecular, purity, qhov hnyav, thiab tus naj npawb ntawm cov polypeptide.

Net nyhav yog dab tsi?Cov ntsiab lus peptide yog dab tsi?

Tom qab lyophilized peptide feem ntau fluffy thiab fluff-zoo li, nws tseem yuav muaj cov kab dej ntau, cov kuab tshuaj adsorbed thiab ntsev vim yog cov yam ntxwv ntawm peptide nws tus kheej.Qhov no tsis tau txhais hais tias lub purity ntawm peptide tsis txaus, tab sis hais tias qhov tseeb cov ntsiab lus ntawm peptide yog txo los ntawm 10% mus rau 30%.Qhov hnyav ntawm peptide yog qhov hnyav ntawm peptide rho tawm cov dej thiab cov ions protonated.Txhawm rau kom ntseeg tau tias qhov concentration ntawm peptide, cov tshuaj tsis yog peptide yuav tsum tau muab tshem tawm ntawm cov peptide crude.

Yuav ua li cas ntshiab peptide?

Peb lub tuam txhab tuaj yeem muab cov qib purity sib txawv rau cov neeg siv khoom xaiv los ntawm, los ntawm cov khoom nyoos mus rau> 99.9% purity.Raws li cov neeg siv khoom xav tau peb tuaj yeem muab purity> 99.9% ultra-ntshiab polypeptide.
