Egtazic acid CAS: 67-42-5 Tus nqi tsim khoom

Calcium chelation: EGTA muaj kev sib raug zoo rau cov calcium ions thiab tuaj yeem khi rau lawv, txo qhov concentration ntawm cov calcium dawb hauv cov kua. Cov yam ntxwv no ua rau EGTA muaj txiaj ntsig zoo hauv kev kawm txog lub luag haujlwm ntawm calcium hauv ntau yam txheej txheem biological.

Calcium buffer: EGTA feem ntau siv los tsim cov calcium uas tsis muaj lossis calcium tsawg rau kev sim. Los ntawm kev chelating calcium, EGTA pab tswj kom muaj qhov concentration ntawm calcium ions hauv cov kua, uas ua rau cov kws tshawb fawb tswj tau cov tshuaj tiv thaiv uas nyob ntawm calcium.

Kev hloov kho cov haujlwm ntawm cov enzyme: Ntau cov enzymes xav tau cov hlau ions tshwj xeeb, suav nrog calcium, rau lawv cov haujlwm. EGTA tuaj yeem siv los hloov kho cov haujlwm ntawm enzyme los ntawm kev chelating thiab tshem tawm cov hlau ions uas xav tau no ntawm cov tshuaj sib xyaw.

Kev sib cais ntawm cov cell: EGTA muaj txiaj ntsig zoo rau kev sib cais ntawm cov cell thiab cov txheej txheem sib cais ntawm cov ntaub so ntswg. Nws pab rhuav tshem kev sib cuam tshuam ntawm cov cell-cell thiab cov cell-extracellular matrix los ntawm kev chelating calcium-dependent adhesion molecules, ua rau cov cell sib cais.

Kev tshawb fawb txog qhov ntsuas calcium: Lub peev xwm ntawm EGTA los chelate calcium ions yog qhov zoo rau kev tshawb fawb txog qhov ntsuas calcium. Los ntawm kev tswj qhov concentration ntawm cov calcium ions dawb nrog EGTA, cov kws tshawb fawb tuaj yeem soj ntsuam qhov tseeb ntawm calcium hauv kev xa xov hauv lub hlwb thiab lwm yam txheej txheem ntawm lub cev.

Cov txheej txheem molecular biology: EGTA siv rau hauv ntau yam txheej txheem molecular biology xws li DNA thiab RNA rho tawm, protein purification, thiab enzyme assays. Nws pab kom ruaj khov nucleic acids thiab proteins los ntawm kev tiv thaiv kev puas tsuaj los ntawm hlau-ion.

Kev siv cov tshuaj EGTA hauv kev cog qoob loo ntawm lub cev kom tswj tau cov calcium kom tsawg los kawm txog cov txheej txheem ntawm lub cev uas nyob ntawm calcium kom raug. Nws pab tshem tawm cov calcium ntawm cov khoom noj uas loj hlob, ua rau cov kws tshawb fawb tshawb nrhiav lub luag haujlwm ntawm calcium hauv kev tshawb fawb txog lub cev.
