Ukupakisha kwangaphakathi

Ngokuvamile zisetshenziselwa ukupakisha impushana.Futhi zingavimbela ukukhanya kwelanga namanzi ukuba kungabi kubi.

ukupakisha kwangaphandle

Ibhokisi eliqinile lingavikela imikhiqizo yakho ukuthi ingaphahlazeka futhi ibe manzi.

Izinhlelo zokusebenza

I-Solid-Phase Peptide Synthesis (SPPS): Ku-SPPS, i-D-Ls(tfa)-NCA isebenza njengebhuloho lokuxhuma iqembu le-carboxyl lensalela ye-amino acid yangaphambili neqembu le-amino lensalela elandelayo ye-amino acid.Yakha isibopho se-peptide neqembu le-carboxyl le-amino acid yangaphambilini, ingeza ngempumelelo i-amino acid entsha ochungechungeni olukhulayo lwe-peptide.

I-synthesis of Peptides With Specific Sequences: Ngokusebenzisa i-D-Ls(tfa)-NCA, abacwaningi bangahlanganisa ama-peptide aqukethe i-D-lysine, ewusizo ekutadisheni ukwakheka nokusebenza kwamaprotheni noma ukuklama izidakamizwa ze-peptide ngemisebenzi ethile yebhayoloji.Njengoba ukuhlelwa kwe-stereochemical kwe-D- ne-L-amino acid kungathinta umsebenzi webhayoloji wama-peptide, leli khono libaluleke kakhulu.

I-Stereoselective Synthesis: Ngenxa yokuthi i-D-lysine ihluka ngokwe-stereochemically kusukela ku-L-lysine evame kakhulu, ukusetshenziswa kwe-D-Ls(tfa)-NCA kungethula i-stereoelectivity ekuhlanganiseni kwe-peptide.Lokhu kuvumela ukuhlanganiswa kwama-peptide ane-stereoconfigurations ethize, engacwaningwa ngomthelela wawo emsebenzini webhayoloji.

Ukuphakama

1. Sinikeza ngokwezifiso imikhiqizo oyidingayo.
2. Ikhwalithi ephezulu kanye nentengo yokuncintisana inganikezwa.
3. Sithembisa inkambo ephelele yokulandelela.
4. Uhlu lwemibuzo yabahlinzeki kanye nemibhalo yezobuchwepheshe inganikezwa uma isicelo emva kokuhlangabezana nenani elithile.
5. Isevisi enhle yangemuva kokuthengisa noma isiqinisekiso : Noma yimuphi umbuzo wakho uzoxazululwa ngokushesha okukhulu.
6. Thumela imikhiqizo encintisanayo futhi uyithumele emazweni angaphandle ngobuningi njalo ngonyaka.
7. Isampula yamahhala enikezwa ukuhlola ikhwalithi ngaphambi kwanoma iyiphi inkokhelo.
