Trimethylol aminomethane
Jiri
① The intermediate nke fosfomycin, nwekwara ike-eji dị ka vulcanization accelerator, ntecha (ude, ude mmiri), ịnweta mmanụ, paraffin emulsifier, ndu ihe nchekwa.
② Ejiri ya dị ka acid gas absorbent, nkwadebe nke ihe nchekwa, surfactant, emulsifier na osooso.A na-ejikwa ya na njikọ organic.
Usoro mmepụta
Gbari Tris na obere mmiri na-eku ume okpukpu abụọ (300-500ml), tinye HCl, dozie pH na 7.6 na HCl (1N) ma ọ bụ NaOH (1N), n'ikpeazụ tinye mmiri na-eku ume na 1000ml.Mmiri a bụ mmiri mmiri echekwara, echekwara na friji na 4 ℃.
Rịba ama: Uru PH nke Tris-Hcl dịgasị iche na okpomọkụ, ya mere a ga-atụle ya na ọnụ ụlọ okpomọkụ, ya mere, ihe a tụrụ atụ na-adabere na ya.
Njirimara nchekwa
Tris bụ ntọala na-adịghị ike nke nwere pKa nke 8.1 na ụlọ okpomọkụ (25 ℃).Dabere na tiori buffering, oke nchekwa nke Tris buffers dị n'etiti pH7.0 na 9.2.
PH nke ngwọta mmiri nke Tris base bụ ihe dịka 10.5, na nchekwa nke pH uru nwere ike nweta site na ịgbakwunye hydrochloric acid iji mezie pH uru na uru achọrọ.Otú ọ dị, ekwesịrị ịṅa ntị na mmetụta nke okpomọkụ na pKa nke Tris.Ọkwa, PH uru belatara site na 0.03.
1M Tris-HCl 6.8 na 1.5M Tris-HCl 8.8 bụ reagents ndị a na-ejikarị eme ihe maka SDS-PAGE.
Ọ bụ ezie na TAE, TBE na ndị ọzọ reagents synthesized si Tris bụ ndị a na-ejikarị eme ihe maka DNA electrophoresis, TE (pH8.0) bụ nke a na-ejikarị eme ihe maka mgbasa DNA.(TE bụ Tris gbakwunyere EDTA.)
Ọ bụghị naanị na a na-eji Tris buffers dị ka ihe mgbaze maka acid nucleic na protein, mana nwekwara ọtụtụ ihe dị mkpa.A na-eji Tris maka uto kristal protein n'okpuru ọnọdụ pH dị iche iche.Enwere ike iji ike ionic dị ala nke Tris buffer maka ịmepụta eriri etiti nke lamin na C. elegans.Tris bụkwa otu n'ime ihe ndị bụ isi nke protein electrophoresis buffers.Na mgbakwunye, Tris bụ onye etiti na nkwadebe nke surfactants, vulcanization accelerators, na ụfọdụ ọgwụ.A na-ejikwa Tris dị ka ọkọlọtọ titration.
