Qhov xav tau rau E.Coli residual restidual kuaj
Hauv liaj teb xws li Cell thiab Fene Kho, Viral Plasmids nthuav dav thiab fermented siv E. coli ua tus tswv tsev. Lub amplated plasmid xav kom yauv E.Coli Residual DNA tswj tau ua ntej nws tuaj yeem siv rau kev sib kis tau rau 293 lub hlwb thiab pob tus kabmob. Yog li ntawd, kev kuaj pom ntawm E.Coli residual DNA yog qhov tseem ceeb.
Kev cai tswjfwm thiab kev sim cov qauv
Tam sim no leej twg thiab peb FDA Cov Lus Qhia Pom DNA hauv cov khoom tiav los ua cov tsiaj ntawv uas tseem ceeb tshaj 100 pg / tus neeg sawv cev. Cov ntsiab cai dav dav ntawm European Pharconopoeia stipulates tau ntau tshaj li 100 ng / koob tshuaj, thiab hauv cov tshuaj tiv thaiv kab mob siab dua, thiab uas nyob rau hauv cov tshuaj tiv thaiv kab mob siab dua, tab sis hauv cov tshuaj tiv thaiv kab mob siab B pg / koob tshuaj. Lub 2020 tsab ntawm cov xov tooj ntawm Suav pharmacoploeia, Ntu III, cov stipulates uas cov tshuaj lom neeg uas tau tsim nyob rau hauv cov tshuaj tiv thaiv kab mob ntawm cov kab mob cellular uas tau tsim los ntawm cov kab mob cellular uas tau tsim los ntawm cov kab mob cellular lossis fungal matrix yuav tsum tsis pub tshaj 10 ng / koob.
Tsis tas li ntawd, rau cov hau kev ntawm exogenous DNA cov chaw seem kev txiav txim siab, lub chaw muag tshuaj hauv lub teb chaws National Costias tseem muab cov lus pom zoo qhia. U.s. Pharmacopoe 2017 tsab ntawm USP40 - NF35 General Program txog kev txiav txim siab DNA seem, uas yog DNA txoj kev sib tw thiab tiag tiag - lub sijhawm ntsuas kev ntsuas pcr. Cov cuab yeej European tawm tswv yim tiag tiag - Lub sij hawm kom kimntitatal pcr thiab immunoenzyatic txoj kev, ob lub rhiab analytical cov hau kev rau tes ua haujlwm ntawm tes DNA. Lub Tuam Txhab Hluav Taws Xob 2020 version ntawm peb txoj cai tswj hwm dav dav yog DNA sojntsuam cov ntaub ntawv thiab cov fluorescenting thiab kom muaj nuj nqis pccr.
Ntawm lawv, QPCR txoj kev muaj qhov siab dua siab, ua ntu zus rau kev lag luam biopharte, thiab tam sim no tuaj yeem ua qhov kev paub ua tiav rau txhua txoj kab kev lag luam biologics.
Cov ntaub ntawv hais txog cov khoom lag luam xiav
Khoom nta
Nrhiav tau ceev ceev, muaj feem ntau yam ua tau zoo, kev ntsuas qis tshaj plaws uas txwv tsis pub muaj peev xwm ncav cuag "FG" qib.
Cov khoom tsis muaj
- Kev Khawb Ntau Yam: 3.00 × 101 ~ 3.00 × 105fg / μl
- Txwv tsis pub muaj nuj nqis:00 101fg / μl
- Nrhiav kom pom qhov txwv:00 fg / μl
- Precision: CV% ≤ 15%.
Cov teeb meem kev pom zoo thiab kev ceev faj
1. Cov khoom siv no yog rau hauv cov kev tshawb fawb vitro tsuas yog, tsis yog kev kuaj mob.
2. Cov khoom siv yuav tsum siv nyob rau lub sijhawm siv tau.
3. Txhua yam ntawm cov khoom siv tau pom zoo kom tau melted nyob rau hauv ib puag ncig kub tsawg - ib puag ncig thiab ces siv.
4. Tsuas yog ua raws li cov lus qhia ntawm txoj haujlwm, txhua qhov kev siv cov khoom siv txhawb cov khoom seem kom ntseeg tau tias kev pom zoo tshaj plaws.
5. Ua tib zoo saib rau cov kev sib txawv cov kauj ruam hauv lub sijhawm los hloov cov lus qhia - kev sib kis, zam kev qhib lub hau ntev.
6. Qhov kawg cov txiaj ntsig tau yuav cuam tshuam dab tsi los ntawm kev ua haujlwm zoo ntawm cov reagents, tus neeg teb xov tooj kev ua haujlwm thiab ib puag ncig kev xeem.
