Cell fractionation yog ib txoj kev uas tso cai rau qhov sib txawv ntawm a cell kom sib cais los ntawm ib leeg siv centrifugation. Ib zaug lub hlwb tau fractionated, organelles xws li plasma membrane, nucleus, thiab mitochondria ua tau yuav kawm nyias.

Tsuas yog li ntawd, cell fractionation txhais li cas?

Cell fractionation yog txheej txheem siv los cais cellular Cheebtsam thaum khaws cia ib tus neeg ua haujlwm ntawm txhua yam. Lwm yam kev siv ntawm subcellular fractionation yog los muab cov khoom muaj protein ntau ntxiv rau kev ua kom huv ntxiv, thiab pab txhawb kev kuaj mob ntawm ntau lub xeev.

Tsis tas li ntawd, homogenization hauv cell fractionation yog dab tsi? Cell fractionation : Cell fractionation yog txheej txheem rau rupturing hlwb , kev sib cais thiab kev ncua ntawm cell Cov khoom siv hauv isotonic nruab nrab txhawm rau kawm lawv cov qauv, tshuaj muaj pes tsawg leeg thiab kev ua haujlwm. Cell fractionation Muaj 3 kauj ruam: Extraction, Homogenization thiab centrifugation.

Ib yam li ntawd, nws yog nug, dab tsi yog lub hauv paus ntsiab lus ntawm cell fractionation?

Cov ntsiab lus ntawm cell fractionation thiab ultracentrifugation raws li siv los cais cell cov khoom. Cell fractionation yog phua hlwb mus rau hauv nws cov organelles. Cov ntaub so ntswg yog txiav thiab nce mus rau hauv dej khov, isotonic, tsis muaj tshuaj. Qhov no yog ces muab tso rau hauv ib tug blender kom tawg qhib lub hlwb uas yog hu ua 'homogenisation'.

Tus txheej txheem ntawm lub cell yog dab tsi?

Cell biology yog kev kawm txog kev tsim, qauv, kev ua haujlwm, kev sib txuas lus thiab kev tuag ntawm a cell . Kawm ntawv txheej txheem uas tshwm sim hauv ib cell , xws li kev rov ua dua tshiab, kev hloov pauv lub zog, kev thauj mus los ntawm molecular, thiab kev teeb tsa hauv nruab nrab thiab nruab nrab, yog qhov tseem ceeb rau kev nkag siab ntau yam kab mob.
