Uninzi lwezisombululo ezikhoyo zogcino lwentsholongwane zikhoyo ziqulethe ityuwa ye-guanidine (i-guanidine isothiocyanate okanye i-guanidine hydrochloride), eziyi-protein denaturants eziqhelekileyo ze-cell lysis ngexesha lokutsalwa kwe-nucleic acid, kwaye inokwenza iintsholongwane zingasebenzi.Nangona kunjalo, inkqubo yetyuwa ye-guanidine ayinakugcina intsholongwane ye-nucleic acid kwiqondo lobushushu begumbi, ngokulula okukhokelela ekuthotyweni kwesampulu.
Ukuphendula ezi ngxaki zingentla, isisombululo sokugcinwa kwesampulu yetyuwa ye-non-guanidine eyenziwe nguJanMa Gene inemisebenzi yokungasebenzi kwentsholongwane kunye nokugcinwa kwesampulu.I-Virus nucleic acid inokugcinwa kwiqondo lokushisa kweeyure ezingama-24 ngaphandle kokuthotywa, okuvunywa ngamxhelo mnye ngabathengi.
【Ukusetyenziswa kwemveliso】 Isetyenziselwa ukuqokelelwa kwesampulu yentsholongwane, ukugcinwa, kunye nokuthuthwa kweisampulu zentsholongwane, eziqulathe amacandelo entsholongwane angasebenziyo.
【Umzekelo osebenzayo】 I-Nasopharyngeal swab, i-alveolar lavage fluid, njl.
【Inombolo yento kunye neNgcaciso】Inombolo yento: HE10, iinkcukacha :50T/ ikhithi.Ukuhlangabezana neemfuno zovavanyo olulodwa, uvavanyo lwe-5-in-1 okanye i-10-in-1.
【Izinto eziluncedo】
- Akukho tyuwa ye-guanidine, izinzile
- Intsholongwane engasebenziyo, ikhuseleke kakhulu
- Ukugcinwa kwesampuli, yomelele ngakumbi
【Iimpawu zemveliso】
● Ukungasebenzi kwentsholongwane: Isisombululo sokugcinwa siqulethe i-protein ye-protein ye-non-guanidine yetyuwa, enokuthi ikhuphe ngokukhawuleza intsholongwane ekhoyo kwisampuli.Emva koko, usulelo, i-pathogenicity kunye nokuzala kweentsholongwane, ukuphelisa usulelo lwesibini, kwaye ukhusele ukhuseleko lokuhamba kunye nokuvavanya abasebenzi;
● Kulula ukuyisebenzisa: Emva kokuqokelela, abasebenzi bezonyango banokuntywilisela i-swab ngqo kwi-tube yesampuli, kwaye ukusebenza kulula kwaye kulula.Iimpawu ezahlukeneyo zokupakisha zihlangabezana neemfuno zeemeko ezahlukeneyo, kwaye zikwahlangabezana neemfuno ze "10-in-1 yovavanyo lwe-2019-nCoV nucleic acids";
● Uvakalelo oluphezulu: Emva kokuqinisekiswa kokusebenza kweemveliso, ityhubhu yesampuli ingabaigcinwe kwiqondo lokushisa kwegumbi iiyure ezingama-24 kwaye igcinwe kwi-2-8 ℃ iintsuku ezisi-7,ukuphepha ingxaki "engalunganga yobuxoki" ebangelwa ukuthotywa kweesampulu ezineemveliso zemveli kwi-4 ℃ kunye nokuphucula uvakalelo lokubona.
