Fa'atatauga

☑ Tris buffer e le gata ina fa'aogaina lautele e fai ma so'o mo nucleic acids ma polotini, ae e tele fo'i fa'aoga taua.Tris na faʻaaogaina mo le tuputupu aʻe o tioata tioata i lalo ole tulaga pH eseese.
☑ Ole malosi ole ionic ole Tris buffer e mafai ona fa'aogaina e fai ai le alava vavalo ole lamin ile C. elegans.
☑ Tris ose tasi foi o vaega autu ole polotini electrophoresis buffer.
☑E le gata i lea, o le Tris o se tagata vavalo mo le sauniaina o mea faʻafefete, faʻamalosi faʻamalosi ma nisi vailaʻau.O lo'o fa'aogaina fo'i le Tris e fai ma fa'ata'ita'iga titration.
☑Trimethylaminomethane o lo'o fa'aaogaina lautele i le gasegase gasegase ma le manava manava.Ose pa'u alkaline ma e iai sona a'afiaga lelei ile metabolic acidosis ma le gaioiga ole enzyme.
☑Tris e masani ona faʻaaogaina e fai ma paʻu olaola, ma o lona pH e 6.8, 7.4, 8.0, 8.8.O lona fausaga faʻavae, o le tau o le pH e suia tele i le vevela.I le tulaga masani, o le pH e faʻaitiitia i le 0.03 pe a faʻatuputeleina le vevela ile tasi tikeri.Tris o loʻo faʻaaogaina lautele i le sauniuniga o vaifofo paʻu i le biochemistry ma suʻesuʻega mole mole.Mo se fa'ata'ita'iga, o le TAE ma le tbe buffers (fa'aaogaina mo le fa'amavaeina o le nucleic acid) e masani ona fa'aogaina i su'esu'ega fa'aolaola e mana'omia Tris.Ona o loʻo iai vaega amino, e mafai ona tali atu i aldehydes.
☑ Tris ose fa'avae vaivai, ma lona PKA e 8.1 ile vevela potu (25 ℃).E tusa ai ma le talitonuga o le paʻu, o le faʻaogaina lelei o le Tris buffer i le va o le 7.0 ma le 9.2.Ole tau ole pH ole vaifofo vai faavae ole Tris e tusa ole 10.5.E masani lava, e fa'aopoopoina le vaila'au o le hydrochloric e fa'afetaui ai le tau o le pH i le tau mana'omia e maua ai le vaifofo pa'u ma lenei tau pH.I le taimi lava e tasi, e tatau ona tatou gauai atu i le aafiaga o le vevela ile pKa o Tris.Talu ai ona o le Tris buffer o se vaifofo vaivai vaivai, o le DNA o le a deprotonated i sea fofo e faʻaleleia ai lona solubility.E masani ona fa'aopoopo e tagata le EDTA ile Tris hydrochloric acid buffer e fai ai le "Te buffer", lea e fa'aoga mo le fa'amautuina ma le teuina o DNA.Afai o le vaifofo o le vai o le fetuunaiga o le pH ua suia i le acetic acid, o le "Tae buffer" (Tris / acetate / EDTA) e maua, ma le "tbe buffer" (Tris / borate / EDTA) e maua e ala i le suia i le boric acid .O nei paʻu e lua e masani ona faʻaaogaina i suʻesuʻega electrophoresis nucleic acid.
