FAQ

Ndi malire otani pautali wa ma peptides opangira?

Polypeptide yopangidwa ndi kampani yathu ndi 6 ~ 50 amino acid m'litali.Mayendedwe okhazikika agawo lolimba nthawi zambiri amatulutsa ma peptides a 6 mpaka 50 amino acid.

Momwe mungafotokozere nsonga za P+Na ndi P+K ku MALDI(MS)?

Nsonga za Na ndi K nthawi zambiri zimawoneka ku MALDI, ndipo sodium ndi potaziyamu zimachokera kumadzi osungunulira.Ngakhale madzi osungunula ndi opangidwa ndi deionized akhoza kukhala ndi ma ion a sodium ndi potaziyamu omwe sangathe kuchotsedwa kwathunthu.Amakhalanso ndi ioni ndikumanga ku gulu laulere la carboxyl la peptide panthawi ya ma spectrometry.Chifukwa palibe njira yoyeretsera kuchotsa ayoni a sodium ndi potaziyamu m'madzi, nthawi zina zimakhala zosapeŵeka kuti nsonga za sodium ndi potaziyamu ziwonekere pamapu a MALDI MS.

Chonde fotokozani njira yanu yoyeretsera

Ma peptides opangidwa ndi kampani yathu adayeretsedwa ndi HPLC yokonzekera yosinthika yokhala ndi TFA ndi pH 2 yowonjezeredwa pamagawo onse am'manja.Gawo A ndi 0.1% TFA m'madzi ochuluka kwambiri, ndipo gawo B ndi 0.1% TFA mu ACN, pH 2. Chitsanzochi chikhoza kusungunuka mwachindunji mu gawo la A, kapena kusungunuka mu Gawo laling'ono la B ndi kuchepetsedwa ndi gawo la A.Nthawi zina pangakhale kofunikira kusungunula ma peptide a hydrophobic okhala ndi zosungunulira zolimba monga formic acid kapena acetic acid, kutengera kutsata kwa peptide.Pa pH 6.8, nthawi zambiri zimakhala zovuta kusungunula ndikuyeretsa peptide, chifukwa chake timasungunula peptide kaye kenako ndikugwiritsa ntchito magawo awiri amafoni kuti tipeze gradient.Njira yothetsera bafa pa pH 6.8 inali 10 mM ammonium acetate m'madzi oyera kwambiri (gawo la m'manja A), ACN yoyera (gawo B).Zigawo zosiyanasiyana zinasonkhanitsidwa ndikuzindikiridwa ndi MADLI-TOF MS.Purity idawunikidwa ndi HPLC yosinthika.Kenako, peptides chandamale anali lyophilized, ndipo lyophilized peptides anaphatikizidwa mu mbale yaing'ono.

Kodi mumawunika bwanji malonda anu?

Ma peptides onse opangidwa adawunikidwa ndi HPLC ndi MS, kupatula MALDIMS.Popeza ma peptide amapangidwa ndi ma ionization mumayendedwe awo osiyanasiyana, njira za HPLC-MS zitha kugwiritsidwa ntchito kusanthula nsonga za ionization mu HPLC.Zipangizo zathu zamakono [MALDI-MS, HPLC-(ESI)MS (ion trap ndi tetrode array)] zimapereka chitsimikizo chodalirika chowunikira.

Kodi kusungunuka kwa peptide kumagwirizana ndi mtundu wa peptide?

Ma peptides opangidwa samasungunuka bwino, ma peptides ali ndi vuto, sichoncho?

Yankho: Ndizovuta kuneneratu momwe peptide imasungunuka komanso kuti chosungunulira choyenera ndi chiyani.Sizowona kuti pali vuto ndi kaphatikizidwe ka peptide ngati kuli kovuta kusungunuka.

Kodi mumasunga bwanji peptides mu yankho?

Ngati muyenera kusunga ma peptides mumadzimadzi, gwiritsani ntchito chotchinga chotchinga pa PH 5-6 ndikusunga pa -20.℃kukulitsa moyo wa peptides mu yankho.

Kodi ma peptides amakhala nthawi yayitali bwanji mumtsuko?

Ndibwino kuti musasunge ma peptides otsalira mu njira yothetsera.Alumali moyo wa polypeptides mu njira ndi ochepa, makamaka amene ali ndi cysteine, methionine, tryptophan, asparagic acid, glutamic acid, ndi N-terminal glutamic acid motsatizana.Ambiri, kutenga zofunika kuchuluka kwa ntchito, ena amaundana zouma kwa nthawi yaitali yosungirako.
