Ukuchonga ngokuchanekileyo, Ukukhusela Impilo Yesisu: Izisombululo Zovavanyo lwe-H. pylori Ezine-Stop

I-Helicobacter pylori (H. pylori)Ihlelwe yi-World Health Organisation njenge-Group I biological carcinogen kwaye yeyona nto iphambili ebangela isifo se-gastritis esingapheliyo, izilonda ze-peptic, kwanomhlaza wesisu. Ngenxa yesantya esiphezulu sosulelo kwiindawo ezininzi, ukuxilongwa kwangethuba kunye nokuxilongwa ngokuchanekileyo kubalulekile ekuthinteleni nasekulawuleni izifo zesisu. Njengenkampani yobungcali yokuxilongwa kwezonyango, sinikezela ngepotifoliyo epheleleyo yovavanyo olupheleleyo—ukusuka ekuhlolweni kokuqala ukuya ekulinganisweni ngokuchanekileyo—ukuze sihlangabezane neemfuno ezahlukeneyo zeklinikhi kunye nokuhlolwa.

Uvavanyo Olusebenzayo: Uvavanyo Lokuphefumla kunye NeeReagent Ezikhawulezayo

Ukuhlolwa kwempilo enkulu kunye nokuhlolwa kwezigulane ezingalaliswanga, C13/C14Uvavanyo lokuphefumla lwe-Ureaiyaziwa kwihlabathi liphela njengomgangatho wegolide wokufumanisa i-H. pylori, inikezela ngovavanyo olungangenisi ntsholongwane oluchanekileyo oludlula i-95%. I-isotope ye-C13 ayinayo i-radioactive kwaye ifanelekile kubo bonke abantu, kuquka abafazi abakhulelweyo kunye nabantwana, ngelixa uvavanyo lwe-C14 lubonelela ngenye indlela engabizi kakhulu nesebenzayo.

Ngaxeshanye, sinikeza uncedo olululaI-HP-AB (i-antibody)kwayeIikiti zovavanyo olukhawulezayo lwe-HP-AG (antigen). II-HP-ABUvavanyo lufumanisa ii-antibodies ngokusebenzisa igazi okanye i-serum esecaleni komunwe, nto leyo enika iziphumo kwimizuzu eli-15—ilungele uphando lwe-epidemiological.Uvavanyo lwe-HP-AGIfumanisa ii-antigens kwiisampuli zendle, ibonisa ngokuthe ngqo imeko yosulelo olusebenzayo. Isebenza njengesincedisi esisebenzayo kuvavanyo lokuphefumla, ngakumbi kumaqela athile apho uvavanyo olungelulo olunye lunokuba nzima.

Ubungakanani obuchanekileyo: Itekhnoloji ye-Fluorescence Immunoassay

Ukuze sihlangabezane neemfuno zonyango zokujonga izifo kunye novavanyo lokusebenza kakuhle konyango, siqalise ii-reagents ze-HP-AG kunye ne-HP-AB ezinobungakanani ezixhaswa yi-I-WIZ-101kwayeI-WIZ-A203amaqonga. Le nkqubo isebenzisa i-immunochromatography ye-fluorescence exazululwe ngexesha, idibanisa ii-antibodies ezithile kunye nee-microspheres ze-fluorescent. Ngokungafaniyo nemicu yovavanyo olusemgangathweni yendabuko, le teknoloji ivumela ukulinganiswa okuchanekileyo kobuninzi be-antibody/antigen concentrations. Oku akuncedi nje kuphela oogqirha ekuvavanyeni ubunzima bosulelo kodwa kukwavumela uvavanyo oluchanekileyo lweziphumo zonyango lokuphelisa, inika idatha ethembekileyo ngakumbi yokwenza izigqibo zeklinikhi.

Ukususela kuvavanyo lokuphefumula olusekelwe kwi-mass spectrometry ukuya kwi-immunochromatography, ukusuka kuvavanyo lomgangatho ukuya kuvavanyo olusekelwe kwi-fluorescence, sizimisele ukubonelela ngepotifoliyo yemveliso ebanzi enika amandla amaziko ezempilo ukuba afezekise uthintelo oluchanekileyo kunye nolawulo losulelo lwe-H. pylori esiswini.
