Njengoba ukuhlolwa kwe-nucleic acid kuba yinto evamile, ingabe uke wabhekana nalezi zinselele: ama-reagent abeka engcupheni ukuwohloka ngesikhathi sokuthuthwa, izinqubo zokuvula ezivame ukungcola, noma ukulahlekelwa umsebenzi ngenxa yemijikelezo ephindaphindwayo yokuqandisa?
Ubuchwepheshe "obuphikisayo" obuneminyaka eyikhulu—ukomisa nge-vacuum freezer—manje iqhuba ushintsho olukhulu embonini yokuxilonga ama-molecule.
Namuhla, ake sihlole ukuthi kanjaniI-MacroMicroTech (MMT)ibhekana namaphuzu amane amakhulu obuhlungu ngayoukusetshenziswa kanye, komiswe ngokuphelele eqandisiwei-microsphereubuchwepheshe.
I. Ukubuya Okumangalisayo Kobuchwepheshe Obudala: Umlando Omfushane Wokomisa Iqhwa
Ngo-1909, ososayensi baqala ukusebenzisa ukomisa ngeqhwa ukuze balondoloze i-serum; ngo-1919, kwavumela ukugcinwa kwesikhathi eside kwezinhlobo zamagciwane. Njengoba kwakuke kwabizwa ngokuthi “umqaphi wokusebenza kwezinto eziphilayo,” ukomisa ngeqhwa manje sekuvuselelwa futhi kusetshenziswa kabanzi ekuxilongweni kwama-molecule esimanje.
1. Uhambo Olunzima Lwezinto Ezisetshenziswayo Zoketshezi Zendabuko
Kusukela kumkhiqizi kuya kumsebenzisi wokugcina, ama-reagent oketshezi kumele agcinwe ngaphansi kwezimo eziqinile ze-cold-chain kulo lonke isitoreji kanye nokuthuthwa. Ukuphathwa kabi kuvame ukuholela ekuwohlokeni kwama-enzyme, ukungazinzi kwe-probe, kanye nokusabela okuhlulekile—inkinga ephindaphindayo ebhalwe ezifundweni zokuqeqesha kanye nezifundo zamacala.
2. Umjikelezo Wempilo Oyingozi Kakhulu Wezinto Ezingamanzi
Uma selivuliwe, ibhokisi lama-reagent aqandisiwe livame ukubhekana nemijikelezo eminingi yokuncibilika, ukusetshenziswa, kanye nokuqandisa kabusha—kuze kube yilapho selidliwe ngokuphelele noma lilahliwe—okuholela ekulahlekelweni komsebenzi kanye nokuchitha.
Ukomisa ngeqhwa kuxazulula lezi zinselele empandeni. Ngokususa amanzi ngaphansi kwe-vacuum emazingeni okushisa aphansi, ama-enzyme nama-probe “avalelwa” esimweni esizinzile—empeleni acindezela isikhashana ekuwohlokeni kuze kube yilapho esetshenziswa.
II. Izinzuzo Ezine Eziyinhloko: Kungani Ukomisa Ngokuqandisa Kuyisixazululo Esifanele Sokuxilongwa Kwama-Molecular
Ama-microsphere e-MMT asetshenziswa kanye kuphela, aklanywe ngokugcwele, omiswe ngokuqandisa aklanyelwe ukuqeda izithiyo ezibalulekile embonini:
III. Ubuchwepheshe Obuthuthukisiwe: Kungani i-MMT Yakhetha i-Micro Eyomisiwe Ngokuqandisaimbulungas?
Phakathi kwezinhlobo ezahlukene ezifana ne-in-vial noma i-PCR-tube lyophilization, i-MMT iye yaba yiphayonai-micro eyomisiwe ngokuqandisaimbulungaifomethilokho kufeza intuthuko ezintathu ezibalulekile:
wena"OyedwaI-Microsphere= Ukusabela Okuphelele Okukodwa”
I-Microsphere ngayinye engu-2 mm iqukethe zonke izingxenye
—ama-primer, ama-enzyme, ama-dNTP—okuqinisekisa ukunemba nokususa amaphutha okuhlanganisa.
wenaUkuguqulwa Komzuzu O-1
Izinto ezisizayo ezikhethekile zivumela ama-microsphere ukuthi ancibilike ngokushesha ngo-50% kunezindlela ezivamile zomiswa ngokuqandisa.
wenaUkuhambisana kwefomethi evulekile
Iyahambisana nohlu olubanzi lwezinto ezisetshenziswayo namadivayisi (isb., amashubhu e-PCR anezicucu ezingu-8, amafomethi okusetshenziswa kanye), okuqinisekisa ukuguquguquka kuzo zonke izinhlelo zokusebenza.
IV. Ikusasa Liyimanje: Indlela Ukomisa Ngokuqandisa Okuzoyishintsha Ngayo Indlela Yokuxilongwa Kwama-Molecular
Njengoba ukuxilongwa kwama-molecule kusondela ezindaweni zokunakekelwa, ukuhlolwa kwasekhaya, kanye nezilungiselelo zokunakekelwa kwempilo okuyisisekelo, i-MMT isikulungele ngeplatifomu yayo eqinile yokomisa iqhwa.
Isibonelo, ekuhlolweni kwamaphaneli okuphefumula, ama-microsphere omiswe ngokuqandisa aletha imiphumela ethembekile kalula, ngaphandle kochungechunge olubandayo noma ukusetha okuyinkimbinkimbi.
Iphrothokholi Ejwayelekile:
Ku-AIO800
Kusukela"Ukukhathazeka ngeketanga elibandayo"ku-"inkululeko yokushisa kwegumbi,"kusukela"izinqubo eziyinkimbinkimbi"ku-"Ukutholwa kwesinyathelo esisodwa," Ubuchwepheshe bokomisa ngokuqandisa buchaza kabusha imingcele yokuthembeka ekuxilongweni kwama-molecule.
I-MMT izoqhubeka nokuthuthukisa izinto ezintsha endleleni yokuzinza, ukusebenza kahle, ukulula, kanye nokulula—inika amandla ukuxilongwa okunembile ukuze ikhululeke ezinkingeni zesikhathi nendawo.
