Ua ntej centrifugal Devices

Kev piav qhia
Guidling ua ntej centrifugal li muab ceev ceev ultrafiltration, nrog lub peev xwm rau siab concentration yam thiab yooj yim concentrate rov qab los ntawm dilute thiab complex qauv matrices. Lub ultrafiltration ntawm ua ntej centrifugal li yuav tsis ua kom tiav ib tug ntse sib cais ntawm ob molecules nrog zoo sib xws molecular luj. Cov molecules yuav tsum tau sib cais yuav tsum sib txawv los ntawm tsawg kawg yog ib qho kev txiav txim ntawm qhov loj (10X) loj rau kev sib cais zoo. Fractionation siv ultrafiltration muaj txiaj ntsig zoo hauv cov ntawv thov, xws li kev npaj cov khoom tsis muaj protein ntau, kev sib cais ntawm cov ntawv tsis sib xws lossis cov ntawv tsis sib xws los ntawm DNA thiab cov qauv protein, thiab kev ua kom huv ntawm PCR cov khoom los ntawm kev sib xyaw ua ke.

Xaiv qhov tseeb MWCO
Once sample volume is determined, the next step is to select the appropriate MWCO (for ultrafiltration) or pore size (for microfiltration). MWCOs are nominal ratings based on the ability to retain >90 feem pua ​​​​ntawm cov kuab tshuaj ntawm qhov hnyav molecular paub (hauv kilodaltons). Cov khoom siv centrifugal ua ntej muab cov yam ntxwv ntawm kev sib txawv ntawm MWCO daim nyias nyias rau qee qhov kev daws teeb meem. Rau cov proteins, nws raug pom zoo kom xaiv MWCO uas yog peb mus rau rau lub sij hawm me dua li qhov hnyav molecular ntawm cov kua nplaum tau khaws cia. Yog tias tus nqi ntws yog ib qho kev txiav txim siab, xaiv daim nyias nyias nrog MWCO ntawm qhov qis kawg ntawm qhov ntau (3X); Yog hais tias qhov kev txhawj xeeb tseem ceeb yog khaws cia, xaiv ib daim nyias nyias (6X).

Nws yog ib qho tseem ceeb kom paub tias qhov tuav ntawm ib lub molecule los ntawm ib qho ultrafiltration membrane yog txiav txim los ntawm ntau yam, ntawm cov uas nws qhov hnyav molecular ua hauj lwm tsuas yog raws li ib tug general qhia.

Yog li ntawd, xaiv qhov tsim nyog MWCO rau ib daim ntawv thov tshwj xeeb yuav tsum tau xav txog ntau yam xws li cov qauv molecular, tus nqi hluav taws xob, cov qauv concentration, qauv qauv, thiab kev ua haujlwm. Vim tias cov tuam txhab sib txawv siv cov khoom sib txawv los txheeb xyuas MWCO ntawm lawv daim nyias nyias, nws yog ib qho tseem ceeb uas yuav tsum tau ua cov kev sim sim los xyuas seb qhov ua tau zoo ntawm daim nyias nyias hauv ib daim ntawv thov.
