Ungabatholaphi abakhiqizi bemishini yokulebula? Wenzani lo mshini ngokujwayelekile?
Ungabatholaphi abakhiqizi bemishini yokulebula? Wenzani lo mshini ngokujwayelekile? Embonini yokukhiqiza nokukhiqiza, imishini eminingi iye yacwaningwa futhi yasungulwa, futhi ngenxa yokuba khona kwale mishini, ukuthuthukiswa kwemboni yokukhiqiza kuye kwasheshisa. Ku...Funda kabanzi -
Hlobo luni lwemikhiqizo umshini wokulebula ozenzakalelayo ongalebula?
Uma liphezulu izinga lebhizinisi lokukhiqiza elizenzakalelayo, lingafakazela nakakhulu ukuthi ibhizinisi linokuqukethwe okuphezulu kobuchwepheshe futhi lingase libe sendaweni ekahle emqhudelwaneni wemboni. Ukusetshenziswa kobuchwepheshe obusha kungathuthukisa ukukhiqizwa kwamabhizinisi, ngakho-ke ezinqubweni...Funda kabanzi -
Indlela yokuthi abakhiqizi be-IVD bahambe futhi bahlale ngaphansi kwesimo sobhubhane
Selokhu kwaqubuka i-coronavirus entsha, inkungu igubuzelwe ezweni laseChina. Ithimba leNational People's united Front liphendule ngenkuthalo “ubhubhane” lwempi ngaphandle kwentuthu yesibhamu. Kodwa-ke, igagasi elilodwa alikakalinganiswa kanti elinye seliqalile. Lolu bhubhane olusha luqubuka e ...Funda kabanzi -
Iyini i-oligonucleotide?
Ama-Oligonucleotides ama-nucleic acid polymers anokuhlelwa okuklanywe ngokukhethekile, okuhlanganisa i-antisense oligonucleotides (ASOs), i-siRNAs (ama-RNA amancane aphazamisayo), ama-microRNA, nama-aptamers. I-Oligonucleotides ingasetshenziswa ukulungisa ukubonakaliswa kofuzo ngokusebenzisa uchungechunge lwezinqubo, okuhlanganisa i-RNAi, i-target degrad...Funda kabanzi -
Umgomo wokukhipha isigaba esiqinile
I-Solid Phase Extraction (SPE) iyisampula yobuchwepheshe bokwelapha ethuthukiswe kusukela maphakathi nawo-1980. Ithuthukiswa inhlanganisela ye-liquid-solid extraction kanye ne-chromatography ewuketshezi. Ikakhulukazi esetshenziselwa ukuhlukaniswa, ukuhlanzwa kanye nokunothisa amasampula. Inhloso enkulu ukunciphisa umata wesampula...Funda kabanzi -
Ukunciphisa umgomo wokutholwa kwe-coronavirus nucleic acid entsha.
Ukuhlolwa kwe-Nucleic acid empeleni kuwukuthola ukuthi ingabe ikhona yini i-nucleic acid (RNA) ye-coronavirus entsha emzimbeni wesifundo sokuhlolwa. I-nucleic acid yegciwane ngalinye iqukethe ama-ribonucleotides, futhi inombolo nokuhleleka kwama-ribonucleotide aqukethwe kumagciwane ahlukene kuhlukile, okwenza i-vir...Funda kabanzi -
Yiziphi ukusetshenziswa kobuchwepheshe be-PCR
1. Ucwaningo oluyisisekelo ngama-nucleic acid: i-genomic cloning 2. I-Asymmetric PCR yokulungisa i-DNA enomucu owodwa wokulandelana kwe-DNA 3. Ukunqunywa kwezifunda ze-DNA ezingaziwa nge-PCR ephambene 4. I-Reverse transcription PCR (RT-PCR) isetshenziselwa ukuthola izinga ukubonakaliswa kofuzo kumaseli, inani legciwane le-RNA kanye...Funda kabanzi -
Isimiso esiyisisekelo nezici ze-nucleic acid extractor
I-Nucleic Acid Extraction System (I-Nucleic Acid Extraction System) iyinsimbi esebenzisa ama-reagents e-nucleic acid ahambisanayo ukuze iqedele ngokuzenzakalelayo ukukhipha isampula ye-nucleic acid. Isetshenziswa kakhulu ezikhungweni zokulawula izifo, ukuxilongwa kwezifo zomtholampilo, ukuphepha kokumpontshelwa igazi, i-forensic ide...Funda kabanzi
