Eminyakeni yamuva nje, ukuthuthukiswa kwemithi yokugoma i-DNA kubonise isithembiso esibalulekile emkhakheni wokugoma. Le mithi yokugoma isebenza nge
ukwethula ucezu oluncane, oluyisiyingi lwe-DNA (i-plasmid) olufaka ikhodi ye-antigenic ye-pathogen, okwenza amasosha omzimba abone futhi alwe ne-pathogen yangempela uma ihlangana nayo. Kodwa-ke, indlela yokulethwa kwale mithi yokugomela i-DNA idlala indima ebalulekile ekusebenzeni kwayo kahle. Imijovo yendabuko esekelwe enaliti, nakuba isebenza kahle, iza nezithiyo ezihlukahlukene njenge-aspain, ukulimala kwezinaliti, kanye nokwesaba inaliti. Lokhu kuholele ekuthakaseleni okukhulu kwezinye izindlela zokulethwa, enye yazo okuwumjovo ongenanaliti.
Yini Izijovo Ezingenanalithi?
Izijovo ezingenanalithi zingamadivayisi aklanyelwe ukuletha imithi noma imithi yokugoma ngaphandle kokusebenzisa inaliti evamile. Basebenza ngokusebenzisa i-high-pressure jet ukuze bangene esikhunjeni futhi bakhululeinto ngqo esicutshini. Lobu buchwepheshe bekulokhuamashumi eminyaka kodwa isanda kuthola ukunakwa okwengeziwe ngenxa yentuthuko ekwakhiweni kwayo nokusebenza kwayo.
Izinzuzo Zokujova Ezingenanalithi
Ukulethwa Okungenabuhlungu: Enye yezinzuzo ezibalulekile zeama-injection angenanalithi ukunciphisa ubuhlungu nokungakhululeki. Ukungabikho kwenaliti
iqeda ubuhlungu obubukhali obuhambisana nemijovo yendabuko, okwenza okuhlangenwe nakho kube mnandi ezigulini.
Ukuqedwa Kwezingozi Ezihlobene Nenaliti: Izijovo ezingenazinaliti zisusa ingozi yokulimala kwenaliti, okukhathaza kakhulu izilungiselelo zezempilo. Lokhu akuvikeli nje kuphela abasebenzi bezempilo kodwa futhi kunciphisa ingozi yokuthelelana ngezifo kanye nokutheleleka.
Ukuthatha Umgomo Okuthuthukisiwe: Ukwesaba inaliti kuyisizathu esivamile sokungabaza kokugoma. Ngokususa inaliti, lezi zisetshenziswa zingakwazi ukukhulisa ukwamukelwa nokuthathwa komgomo, okubalulekile ezinhlelweni zezempilo zomphakathi.
I-Immunogenicity Ethuthukisiwe: Olunye ucwaningo luye lwaphakamisa ukuthi izijovo ezingenanaliti zingathuthukisa ukuzivikela komzimba emithini yokugoma. Ijethi enengcindezi ephezulu ingasiza ekuhlakazweni okungcono komgomo ngaphakathi kwethishu, okuholela ekuphenduleni kokuzivikela okuqinile.
Ukusebenza Kwezijovo Ezingenazinaliti Zemijovo ye-DNA
Ukusebenza kahle kwezijovo ezingenanalithi ekuletheni imigomo ye-DNA kuyindawo yocwaningo olusebenzayo. Ucwaningo oluningana lubonise imiphumela ethembisayo:
Ukuthathwa Kwe-DNA Okuthuthukisiwe: Indlela yokulethwa kwengcindezi ephezulu yezijovo ezingenanaliti yenza kube ngcono ukutholwa kwama-plasmids e-DNA ngamaseli. Lokhu kubalulekile emithini ye-DNA njengoba i-plasmid idinga ukungena kumaseli ukuze ikhiqize amaprotheni e-antigenic.
Ukusabela Okuqinile Kwamasosha omzimba: Ucwaningo luveze ukuthi imigomo ye-DNA elethwa ngezijovo ezingenanaliti ingadala amandla aqinile nangaphezulu.
ukusabela okuqhubekayo kokuzivikela komzimba uma kuqhathaniswa nezindlela zendabuko ezisekelwe inaliti. Lokhu kubangelwa ukulethwa okuphumelelayo kanye nokusatshalaliswa okungcono komgomo ngaphakathi kwezicubu.
Ukuphepha Nokubekezeleleka: Izijovo ezingenazinaliti zitholwe ziphephile futhi zibekezelelwa kahle iziguli. Ukungabikho kwezinaliti kunciphisa ingozi yokusabela okubi endaweni yomjovo, njenge-aspain, ukuvuvukala, nokubabomvu.
Izinselelo Nokucatshangelwa
Nakuba izijovo ezingenanaliti zinikeza izinzuzo eziningi, kusenezinselele nokucatshangelwa okufanele kubhekwane nazo:
Izindleko: Imishini yokujova engenazinaliti ingabiza kakhulu kunesirinji evamile, engakhawulela ukutholwa kwayo okusabalele, ikakhulukazi kuzilungiselelo zezinsiza eziphansi.
Ukuqeqeshwa: Ukuqeqeshwa okufanele kuyadingeka ukuze abahlinzeki bezokunakekelwa kwempilo basebenzise imijovo engenanalithi ngempumelelo. Ukusetshenziswa okungalungile kungaholela ekulethweni komgomo okungafanele kanye nokuncipha kokusebenza ngempumelelo.
Ukunakekelwa Kwedivayisi: Lawa madivayisi adinga ukunakekelwa okujwayelekile nokulinganisa ukuze kuqinisekiswe ukusebenza okufanayo. Lokhu kungaba inselele yokuhlela kwezinye izindawo zokunakekelwa kwezempilo.
Isiphetho
Izijovo ezingenazinaliti zimelela intuthuko ethembisayo ekulethweni kwemithi yokugomela i-DNA. Ikhono labo lokuhlinzeka ngokungenabuhlungu, okuphephile, futhiukugoma okungase kube nempumelelo kakhudlwana kwenza indoda ithandeke kwezinye izindlela ezisekelwe yenaliti. Nakuba kunezinselele okufanele zinqotshwe, ukuthuthukiswa okuqhubekayo kanye nokucwengwa kwalobu buchwepheshe kungaba neqhaza elikhulu ekuthuthukiseni ukulethwa komgomo kanye nemiphumela yezempilo yomphakathi. Njengoba ucwaningo luqhubeka, izijovo ezingenanalithi zingaba ithuluzi elijwayelekile ekulweni nezifo ezithathelwanayo, zinikeze umuzwa wokugoma onethezeke kakhudlwana futhi osebenza kahle kubo bonke.
