TES, sodium ntsev, yog cov qauv analogue rau Tris tsis nrog pKa ntawm 7.4, ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov lom neeg.Tsis tas li ntawd, TES tsis nthuav tawm cov chelation thiab nag lossis daus teeb meem pom nyob rau hauv ntau lub buffers, ua rau nws muaj txiaj ntsig zoo hauv kab lis kev cai xov xwm uas xav tau cov cations hlau.TES yog qhov tsis haum rau kev loj hlob ntawm cov cell epidermal ntawm pH 7.4 - 7.9, thiab tseem muaj txiaj ntsig zoo rau kev kawm succinate oxidation.
Kev Siv: Ib qho tsis siv TES dawb acid tuaj yeem npaj tau los ntawm titrating cov kua qaub dawb (sc-206102) nrog sodium hydroxide mus rau qhov xav tau pH, siv li ntawm ib nrab-sib npaug ntawm NaOH.Xwb, kev daws teeb meem ntawm equimolar TES dawb acid
thiab TES sodium tuaj yeem sib xyaw kom ua tiav qhov tsis muaj pH xav tau.
