U tseba joang bohloeki ba peptide?
Ho hloeka ha peptide ho bontšoa tlalehong ea COA ea sehlahisoa, e bua ka chromatogram.
Lihlahisoa tsa peptide tsa Peptide Biochemical Limited li kenyelletsa tlhahlobo efe?
Khamphani ea rona, lihlahisoa tsohle li na le tlhahlobo e felletseng ea boleng, ho kenyelletsa MS, HPLC, solubility.Liteko tse khethehileng le tsona li ka koptjoa, joalo ka qeto ea litaba tsa peptide, tlhahlobo ea amino acid, joalo-joalo.
Ba bang ba bona ba re ACN, seo se bolela'ng?
"ACN" ke acetonitrile, e sebelisetsoang ho thusa ho qhala li-peptide tse itseng.
Na o hloka ho qhaqha polypeptides ho PH e khethehileng?
Tlaleho e tla bontša hore na ho hlokahala litekanyetso tse khethehileng tsa PH.Haeba ho na le litlhoko tse khethehileng tsa PH, sena se tla hlokomeloa tlalehong ea COA.
Ho thoe'ng haeba li-peptide li sa qhibilihe hantle?
Ka mokhoa o tloaelehileng, peptide e tlameha ho qhibiliha ka metsing a hloekisitsoeng ka lekhetlo la pele 'me e loketse haholoanyane bakeng sa metsi a bolaeang likokoana-hloko.Haeba ho qhibiliha e ntse e le bothata, leka mehato e latelang: Sonic degradation e thusa ho qhaqha li-peptide.Tharollo ea ho hlapolla ka palo e nyane ea asiti ea acetic (10% ea mahloriso) e thusa ho qhaqha li-peptide tse akaretsang, 'me tharollo e nang le metsi e nang le ammonia e thusa ho qhaqha li-peptide tse nang le asiti.E boetse e khothaletsoa ho qhaqha peptide ka har'a mahloriso a holimo ebe o e hlapolla boemong ba eona bo tloaelehileng ba ho sebetsa ka metsi kapa buffer, kaha letsoai le ka baka polymerization.(Ka hona, buffer e tlameha ho eketsoa ka mor'a hore peptide e qhibilihe ka ho feletseng.)
Hobaneng ha li-peptide li fapana ka ho solubility?
Solubility ke boemo ba bohlokoa bakeng sa ts'ebeliso ea li-peptide.E 'ngoe le e' ngoe ea amino acid e na le lik'hemik'hale tsa eona tsa ka hare.Ka mohlala, leucine, isoleucine, le valerine li na le hydrophobic, ha li-amino acid tse ling tse kang lysine, histidine le arginine li na le hydrophilic.Ka hona, li-peptide tse fapaneng li na le solubility e fapaneng ho latela sebopeho sa tsona.
U ka tlosa polypeptides joang?
Solubility e boletsoe tlalehong ea COA ea sehlahisoa.Ka kopo bala litaelo ka hloko pele o qala ho qhibiliha.Solubility e ka fapana ho latela mofuta oa peptide.Tharollo e tloaelehileng haholo ke ho qhaqha 1mg ea peptide ka 1ml ea metsi a hloekisitsoeng.
