He aha te HEPES CAS 7365-45-9?

Ko te HEPES CAS 7365-45-9 kua whakaahuatia ko tetahi o nga tino pai mo nga mahi katoa e waatea ana mo te rangahau koiora. I te pH koiora, he zwitterionic te rāpoi ngota, a ka whai hua hei parepare i te pH 6.8 ki te 8.2 (pKa 7.55). I te nuinga o te wa ka whakamahia i roto i te ahurea pūtau i te kukū i waenga i te 5mM ki te 30 mM. Kua whakamahia te HEPES ki te maha o nga momo tono, tae atu ki te ahurea kiko. Kei te whakamahia nuitia ki te aukati i nga papaaaahua ahurea pūtau ki te hau. Ka kitea e te HEPES tana whakamahinga i roto i nga whakamatautau in vitro i Mg.

Taupānga

Kore paitini ki te pūtau. Ka whakamahia hei parepare katote hauwai, ka taea te whakahaere i te awhe pH mo te wa roa. Ko te kukū ko te 10-50mmol/L. Ko te tikanga, ka taea e te 20mmol/LHEPES i roto i te wairewa matūkai te whai kaha ki te aukati.
