FAQ

Waa maxay xaddidaadaha dhererka peptides synthetic?

Polypeptide-ka ay farsamaysay shirkadeena waa 6 ~ 50 amino acids dherer ahaan.Hababka isku dhafka adag ee caadiga ah waxay caadi ahaan soo saaraan peptides 6 ilaa 50 amino acids.

Sidee loo sharxi karaa P+Na iyo P+K ugu sarreeya MALDI(MS)?

Meesha ugu sarreysa Na iyo K ayaa badanaa lagu arkaa MALDI, sodium iyo potassium waxay ka yimaadaan biyaha dareeraha ah.Xataa biyaha la miiray iyo kuwa fuuq-baxay waxay ka koobnaan karaan xaddi cadad ah oo soodhiyam iyo botaasiyam ah oo aan si buuxda loo saari karin.Waxay sidoo kale ionize iyo xidhaan kooxda karboksyl ee bilaashka ah ee peptide inta lagu jiro spectrometry mass.Sababtoo ah ma jiro nidaam nadiifin ah oo ka saara sodium iyo potassium ions biyaha, mararka qaarkood waa lama huraan in sodium iyo potassium ugu sarreeya ay ka muuqdaan khariidadda MALDI MS.

Fadlan sharax xeeladdaada nadiifinta

peptides-ka ay farsamaysay shirkadeena waxaa lagu sifeeyay diyaarinta weji rogan ee HPLC iyadoo TFA iyo pH 2 lagu daray labada weji ee mobilada.Wajiga A waa 0.1% TFA biyaha saafiga ah, iyo wejiga B waa 0.1% TFA ee ACN, pH 2. Muunada waxaa si toos ah loogu milmi karaa marxaladda A, ama lagu milmay qadar yar oo ah wajiga B waxaana lagu qasi karaa wejiga A.Mararka qaarkood waxaa laga yaabaa inay lagama maarmaan noqoto in lagu milmo peptides hydrophobic leh dareerayaal xooggan sida formic acid ama acetic acid, taas oo ku xidhan habka peptide-ka.Marka pH 6.8 ah, guud ahaan way adagtahay in la milo oo la nadiifiyo peptide-ka, markaa waxaanu guud ahaan kala diri karnaa peptide-ka marka hore ka dibna waxaan isticmaalnaa laba weji oo wareeg ah oo loogu talagalay elution gradient.Xalka kaydka ah ee pH 6.8 wuxuu ahaa 10 mM ammonium acetate ee biyo saafi ah (wajiga wareega A), ACN saafi ah (wajiga wareega B).Qaybo kala duwan ayaa la ururiyay oo lagu aqoonsaday MADLI-TOF MS.Nadiifinta waxaa lagu falanqeeyay weji rogan ee HPLC.Kadibna, peptides-ka bartilmaameedka ah ayaa la lyophilized, iyo peptides-ka lyophilized ayaa lagu daray fijaanno yaryar.

Sideed ula socotaa alaabtaada?

Dhammaan peptides-ka synthetic waxaa falanqeeyay HPLC iyo MS, marka laga reebo MALDIMS.Maaddaama peptides-ka ionized ee isku xigxiga iyaga u gaar ah ee spectrometer mass kala duwan, HPLC-MS farsamooyinka waxaa loo isticmaali karaa si ay u falanqeeyaan kuwa ugu sarreeya ee ionization ee HPLC.Qalabkeena farsamada [MALDI-MS, HPLC- (ESI) MS (ion trap iyo tetrode array)] waxay siisaa dammaanad lagu kalsoonaan karo oo falanqaynta.

Miyay milanka peptide la xidhiidha tayada peptide?

peptides-ka synthetic si fiican uma milmaan, peptides-ka ayaa dhibaato haysta, sax?

J: Way adag tahay in la saadaaliyo sida saxda ah ee peptide-ku u milmay iyo waxa dareeraha ku habboon yahay.Run ma aha in ay dhibaato ka jirto isku dhafka peptide haddii ay adagtahay in la milmo.

Sideed u ilaalisaa peptides ee xalka?

Haddii ay tahay inaad ku kaydiso peptides-kaaga dareeraha ah, isticmaal bakhaar jeermis dilay PH 5-6 kuna kaydi -20℃si loo kordhiyo nolosha peptides-kaaga xalka.

Intee in le'eg ayay peptides ku jiraan xalka?

Way fiicantahay in aan lagu kaydin haraaga peptides ee xalka.Nolosha shelf ee polypeptides ee xalka waa mid aad u xaddidan, gaar ahaan kuwa leh cysteine, methionine, tryptophan, asparagic acid, glutamic acid, iyo N-terminal glutamic acid ee isku xigxiga.Guud ahaan, qaado qiyaasta lagama maarmaanka ah ee isticmaalka, inta kale ee barafku waa la qalajiyey kaydinta muddada dheer.
