Ke pheletso efe e molemo bakeng sa lipatlisiso tsa ka?
Ka mokhoa o ikhethileng, peptide e qetella ka sehlopha sa amino sa mahala sa N-terminal le sehlopha sa mahala sa carboxyl sa C-terminal.Tatelano ya peptide hangata e emela tatelano ya protheine ya mme.E le hore u be haufi le protheine ea 'mè, qetellong ea peptide hangata e hloka ho koaloa, ke hore, n-terminal acetylation le C-terminal amidation.Phetoho ena e qoba ho kenngoa ha tefiso e feteletseng, hape e etsa hore e khone ho thibela ketso ea exonucliase, e le hore peptide e tsitsa haholoanyane.
Ke li-polypeptide life tse fetotsoeng tse ngotsoeng tse ka etsoang ka peptide ea China?
Khamphani ea rona e fana ka mefuta e fapaneng ea mabitso a peptide a fetotsoeng, joalo ka acetylation, biotin labeling, phosphorylation modification, fluorescence modified, le eona e ka etsoa ho latela litlhoko tsa hau tse ikhethang.
U ka tlosa polypeptides joang?
Ho qhibiliha ha polypeptide ho itšetlehile haholo ka sebopeho sa eona sa mantlha le sa bobeli, mofuta oa label ea phetoho, mofuta oa solvent le mahloriso a ho qetela.Haeba peptide e sa qhibilihe ka metsing, ultrasound e ka thusa ho e qhaqha.Bakeng sa peptide ea motheo, ho kgothaletswa ho qhaqha ka 10% acetic acid;Bakeng sa li-peptide tse nang le asiti, ho khothaletsoa ho qhibiliha ka 10% NH4HCO3.Li-solvents tsa tlhaho le tsona li ka kenyelletsoa ho li-polypeptide tse sa qhibilihang.Peptide e qhibiliha ka tekanyo e fokolang ea solvent ea organic (mohlala, DMSO, DMF, joala ea isopropyl, methanol, joalo-joalo).Ho khothaletsoa haholo hore peptide e qhibilihe ka har'a motsoako oa organic pele ebe e eketsoa butle-butle metsing kapa buffer e 'ngoe ho fihlela mahloriso a lakatsehang.
Maemo a molemo ka ho fetisisa a paballo ke afe?Peptide e tsitsitse hakae?
Kamora ho ba le lyophilized, polypeptide e ka etsa phofo e phoroselang kapa ea flocculant, e ka qobang ho senyeha pele ho nako ea polypeptide.Maemo a khothaletsoang a polokelo: a.-20℃sebaka sa polokelo kapa se omileng b.Leka ho qoba ho qhibiliha khafetsa c.Leka ho qoba polokelo maemong a tharollo (phofo e omisitsoeng ka leqhoa e ka bolokoa ka liphutheloana tse arohaneng molemong oa tšebeliso) d.Haeba e tlameha ho bolokoa ka tharollo, ho kgothaletswa ho qhaqha li-peptide metsing a sa hloekang tlas'a maemo a fokolang a acid le ho boloka ho -20.℃.
Peptide eaka e tsamaisoa joang?Ho fanoe ka litlaleho life tsa liteko?
Li-polypeptide tsohle tse omisitsoeng ka leqhoa li atisa ho bolokoa ka har'a lijana tse khethehileng tsa 2 ml kapa 10ml tse nang le lintlha tsa pele tsa tlhahlobo le litlaleho tsa synthesis tse nang le boitsebiso ba bohlokoa bo kang tatellano, boima ba limolek'hule, bohloeki, boima ba 'mele le palo ea polypeptide.
Net weight ke eng?Likahare tsa peptide ke eng?
Ka mor'a hore lyophilized peptide hangata e be fluffy le fluff-joaloka, e ntse e ka 'na ea e-na le palo e fokolang ea metsi, litlhare tse adsorbed le matsoai ka lebaka la litšobotsi tsa peptide ka boeona.Sena ha se bolele hore bohloeki ba peptide ha boa lekana, empa hore litaba tsa sebele tsa peptide li fokotsehile ka 10% ho ea ho 30%.Boima ba nete ba peptide ke boima ba 'nete ba peptide ho tlosa metsi le li-ion tse nang le protonated.E le ho etsa bonnete ba hore peptide e tletse, lintho tseo e seng tsa peptide li hloka ho tlosoa ho peptide e tala.
