Feem ntau cov proteins, txawm li cas los xij, tshwm sim hauv cov khoom me me lossis tshwm sim hauv cov kab mob uas cov protein tsis tuaj yeem ua kom huv tau yooj yim. Protein overexpression Protein overexpression Protein ntau lawm yog txheej txheem biotechnological ntawm tsim cov protein tshwj xeeb. Nws yog feem ntau ua tiav los ntawm kev siv cov noob qhia hauv cov kab mob xws li hais tias nws nthuav tawm ntau cov gene recombinant. https://en.wikipedia.org › wiki › Protein_production
Protein production - Wikipedia
protocols tsim kom muaj ntau yam ntawm cov proteins uas xav tau rau kev kawm ntxiv, tso cai rau cov kws tshawb fawb los kawm kom muaj nuj nqis tsawg, tsis tshua muaj, tshuaj lom thiab txawm tias hloov pauv cov proteins.
Vim li cas peb thiaj li nthuav tawm cov protein ntau?

Lub hom phiaj ntawm kev nthuav tawm ntau dhau yog dab tsi?
Gene overexpression yog txheej txheem uas ua rau muaj ntau lub hom phiaj proteinqhia tom qab. Cov txheej txheem yuav nyob rau hauv lub xovtooj ntawm qhov chaw uas cov noob nyob rau hauv keeb kwm los yog nyob rau hauv lwm yam kev qhia.
YDab tsi qhia txog cov protein?
Protein expression yog hais txog txoj kev uas cov proteins tau tsim, hloov kho thiab tswj cov kab mob nyob. Hauv kev tshawb fawb txog cov protein, lub sij hawm siv tau rau ob qho tib si ntawm kev kawm lossis kev sim cov txheej txheem uas xav tau los tsim cov protein.
