FAQ

Yeyiphi imida kubude beepeptides zokwenziwa?

I-polypeptide eyenziwe yinkampani yethu yi-6 ~ 50 amino acids ubude.Iinkqubo eziqhelekileyo zesigaba esiqinileyo se-synthesis ngokuqhelekileyo zivelisa i-peptides ye-6 ukuya kwi-50 ye-amino acids.

Uzichaza njani iincopho ze-P+Na kunye ne-P+K kwi-MALDI(MS)?

Incochoyi ye-Na kunye ne-K idla ngokubonwa kwi-MALDI, kwaye i-sodium kunye ne-potassium ziphuma emanzini anyibilikayo.Kwanamanzi adityanisiweyo kunye namanzi adibeneyo anokuqulatha izixa zesodium kunye ne-potassium ion ezingenakususwa ngokupheleleyo.Zikwayiyoni kwaye zibophelela kwiqela le-carboxyl yasimahla yepeptide ngexesha le-mass spectrometry.Ngenxa yokuba akukho nkqubo yokucoca yokususa i-sodium kunye ne-potassium ion emanzini, ngamanye amaxesha akunakuphepheka ukuba iincopho zesodium kunye ne-potassium zivela kwimephu ye-MALDI MS.

Nceda uchaze isicwangciso sakho sokucoca

Iipeptides ezidityaniswe yinkampani yethu zacocwa ngokulungiswa kwesigaba se-HPLC esilungisiweyo kunye ne-TFA kunye ne-pH 2 yongezwe kuzo zombini izigaba zeselula.Isigaba A yi-0.1% ye-TFA kumanzi a-ultra-pure, kwaye isigaba B yi-0.1% ye-TFA kwi-ACN, i-pH 2. Isampuli inokuchithwa ngokuthe ngqo kwi-A isigaba, okanye ichithwe kwisixa esincinci se-B kwaye ihlanjululwe ngesigaba se-A.Ngamanye amaxesha kunokuba yimfuneko ukunyibilikisa i-hydrophobic peptides ene-solvents ezinamandla ezifana ne-formic acid okanye i-acetic acid, kuxhomekeke kulandelelwano lwe-peptide.Kwi-pH 6.8, ngokuqhelekileyo kunzima ukunyibilikisa kunye nokucoca i-peptide, ngoko ke siqhele ukunyibilikisa i-peptide kuqala kwaye emva koko sisebenzise izigaba ezibini eziphathwayo zokukhanya kwegradient.Isisombululo se-buffer kwi-pH 6.8 yayiyi-10 mM i-acetate ye-ammonium kumanzi ahlambulukileyo (i-mobile phase A), i-ACN ecocekileyo (isigaba se-mobile B).Amacandelo ahlukeneyo aqokelelwa aza achongwa yi-MADLI-TOF MS.Ubunyulu buhlalutywe yi-HPLC yesigaba esibuyiselwe umva.Emva koko, i-peptides ekujoliswe kuyo yayiyi-lyophilized, kwaye i-lyophilized peptides yadityaniswa kwiibhotile ezincinci.

Uzibeka njani esweni iimveliso zakho?

Zonke iipeptide zokwenziwa zahlalutywa yi-HPLC kunye ne-MS, ngaphandle kwe-MALDIMS.Kuba iipeptide zenziwe nge-ionized ngokulandelelana kwazo kwiispectrometers zobunzima ezahlukeneyo, ubuchule be-HPLC-MS bunokusetyenziswa ukuhlalutya ezo zincopho ze-ionization kwi-HPLC.Izixhobo zethu zobugcisa [MALDI-MS, HPLC-(ESI)MS (i-ion trap kunye ne-tetrode array)] ibonelela ngesiqinisekiso esithembekileyo sokuhlalutya.

Ngaba ukunyibilika kwepeptide kunxulumene nomgangatho wepeptide?

Iipeptides zokwenziwa azinyibiliki kakuhle, iipeptides zinengxaki, akunjalo?

A: Kunzima ukuqikelela ukuba injani na i-peptide enyibilikayo kunye nokuba yintoni na isinyibilikisi esifanelekileyo.Akuyonyani ukuba kukho ingxaki nge-peptide synthesis ukuba kunzima ukuyinyibilika.

Uzigcina njani iipeptides kwisisombululo?

Ukuba kufuneka ugcine iipeptides zakho kulwelo, sebenzisa isithinteli esintsholongwane e-PH 5-6 kwaye ugcine ku -20℃ukwandisa ubomi beepeptide zakho kwisisombululo.

Ingaba iipeptides zihlala ixesha elingakanani kwisinyibiliko?

Kungcono ukuba ungagcini iipeptide eziseleyo kwisisombululo.Ubomi beshelufu ye-polypeptides kwisisombululo buncinci kakhulu, ngakumbi abo bane-cysteine, i-methionine, i-tryptophan, i-asparagic acid, i-glutamic acid, kunye ne-N-terminal glutamic acid ngokulandelelana.Ngokubanzi, thabatha inani elifunekayo lokusetyenziswa, intsalela yomkhenkce yomiswe ukugcinwa kwexesha elide.
