Size-exclusion chromatography, tseem hu ua molecular sieve chromatography, yog ib txoj hauv kev chromatographic uas cov molecules hauv cov tshuaj sib cais los ntawm lawv qhov loj me, thiab qee qhov hnyav molecular. Nws feem ntau yog siv rau cov molecules loj lossis macromolecular complexes xws li cov proteins thiab muaj cov polymers.
Gel filtration chromatography yog dab tsi?
Gel filtration chromatography, ib hom me me tsis suav nrog chromatography, tuaj yeem siv los ua cov fractionate molecules thiab complexes hauv cov qauv rau hauv cov feem ntau nrog rau qhov loj me, kom tshem tawm tag nrho cov molecules loj dua ib qhov loj me los ntawm cov qauv, los yog ua ke ntawm ob qho kev ua haujlwm.
gel filtration chromatography ua haujlwm li cas?
Gel filtration (GF) chromatography cais cov proteins nkaus xwb los ntawm lub hauv paus ntawm molecular loj Kev sib cais tau ua tiav siv cov porous matrix uas cov molecules, rau cov laj thawj tsis zoo, muaj ntau qib sib txawv. nkag mus--i.e., cov molecules me me muaj kev nkag tau ntau dua thiab cov molecules loj dua raug cais tawm ntawm matrix.
Gel Lim siv dab tsi?
Gel pom yog ua tiav siv cov hlaws ntxeem tau raws li kev txhawb nqa chromatographic Ib kem tsim los ntawm cov hlaws dai yuav muaj ob qhov ntsuas tau ua kua, qhov ntim sab nraud, suav nrog cov kua nruab nrab ntawm cov hlaws dai., thiab cov ntim sab hauv, muaj cov kua hauv qhov pores ntawm cov hlaws dai.
Vim li cas gel pom chromatography pab tau?
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm gel-filtration chromatography yog tias kev sib cais tuaj yeem ua tau raws li cov xwm txheej tshwj xeeb tsim los tswj kev ruaj ntseg thiab kev ua haujlwm ntawm cov molecule ntawm kev txaus siab yam tsis muaj kev daws teeb meem.
