EDTA tuaj yeem siv los tiv thaiv kev degradation ntawm DNA thiab RNA thiab ua kom tsis muaj cov nucleases uas xav tau cov hlau ions. EDTA kuj tseem siv tau los ua kom tsis muaj hlau ion-yuav tsum tau enzymes.
EDTA yog dab tsi thiab nws txoj haujlwm?
Ib yam tshuaj uas khi qee yam hlau ions, xws li calcium, magnesium, lead, thiab hlau.

Tus qauv EDTA yog dab tsi?
Txoj kev classic ntawm kev txiav txim siab calcium thiab lwm yam cations tsim nyog yog titration nrog cov qauv kev daws teeb meem ntawm ethylenediaminetetraacetic acid (EDTA). … Lub disodium dihydrate ntawm EDTA, Na2H2Y•2H2O yog siv los npaj cov txheej txheem EDTA daws.
Koj ua li cas EDTA daws?
Txhawm rau npaj EDTA ntawm 0.5 M (pH 8.0): Ntxiv 186.1 g ntawm disodium EDTA•2H2O rau 800 mL ntawm H 2 O. Sib sib zog nqus rau ntawm magnetic stirrer . Kho cov pH rau 8.0 nrog NaOH (~ 20 g ntawm NaOH pellets). Dispense rau hauv aliquots thiab sterilize los ntawm autoclaving.
