Piav txog txheej txheem thiab lub hom phiaj ntawm cell fractionation . Tus kheej kev faib ua feem yog ib txoj kev uas yuav siv hlwb sib nrug thiab cais loj organelles thiab lwm yam sub cellular cov qauv ntawm ib leeg. Cov lub hom phiaj yog cais/fractionate cell cov khoom raws li qhov loj thiab qhov ntom.

Ntawm no, cell fractionation siv rau dab tsi?

Cell fractionation yog tus txheej txheem siv rau cais cellular Cheebtsam thaum khaws cia ib tus neeg ua haujlwm ntawm txhua yam khoom. Qhov no yog ib txoj kev uas yog Ameslikas siv rau ua qauv qhia cellular qhov chaw ntawm ntau yam txheej txheem biochemical.

Tsis tas li ntawd, cov cuab yeej twg siv los faib cov hlwb? centrifuge

Ua raws li qhov no, lub hauv paus ntsiab lus ntawm cell fractionation yog dab tsi?

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 cov dej khov txias, 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'.

Dab tsi yog intercellular junctions thiab yog vim li cas lawv tseem ceeb?

Plasmodesmata , nruj junctions , desmosomes , kev sib tshuam . Lawv tso cai rau kev sib txuas lus ntawm cov hlwb. Tso cai rau tej yam kis ntawm cov hlwb.
