MOPS sodium ntsev Siv Thiab Synthesis
| Kev piav qhia | MOPS sodium ntsev yog tus neeg sawv cev buffering siv hauv biochemistry thiab molecular biology uas tau xaiv thiab piav qhia los ntawm Good et al.Nws yog ib qho zwitterionic, morpholinic tsis uas muaj txiaj ntsig zoo rau pH ntau ntawm 6.5 - 7.9 thiab feem ntau siv rau cov kab lis kev cai xov tooj ntawm tes, raws li kev khiav tsis nyob hauv electrophoresis thiab rau kev ntxuav cov protein hauv chromatography.MOPS tsis muaj peev xwm los tsim ib qho nyuaj nrog cov hlau ions feem ntau thiab pom zoo siv los ua qhov tsis sib koom ua ke hauv kev daws teeb meem nrog hlau ions.MOPS feem ntau yog siv rau hauv cov kab lis kev cai buffered rau cov kab mob, cov poov xab, thiab cov tsiaj txhu.MOPS tau suav tias yog qhov tsis zoo rau kev siv cais RNA hauv agarose gels.Nws raug nquahu kom ua kom tsis muaj menyuam MOPS buffers los ntawm kev pom ntau dua li nrog autoclave vim qhov tsis paub tias yog tus kheej ntawm cov khoom degradation daj uas tshwm sim tom qab ua kom tsis muaj menyuam ntawm MOPS nrog autoclave.Nws yog tsim nyog rau siv nyob rau hauv lub bicinchoninic acid (BCA) assay. MOPS sodium ntsev tuaj yeem sib xyaw nrog MOPS dawb acid kom ncav cuag pH xav tau.Xwb, MOPS dawb acid tuaj yeem titrated nrog sodium hydroxide kom ncav cuag pH xav tau. |
| Chemical Properties | hmoov dawb |
| Siv | MOPS Sodium Salt yog tus neeg sawv cev buffering siv nyob rau hauv cov organic chemistry. |
| Flammability thiab Explosibility | Tsis cais |
| Kev ua lom lom | Ntau lub hom phiaj buffering tus neeg sawv cev siv hauv kev tshawb fawb lom neeg.Ua haujlwm pH ntau hauv cov kua dej: 6.5 - 7.9.Feem ntau siv nyob rau hauv xov tooj ntawm kab lis kev cai xov xwm, raws li ib tug khiav tsis rau gel eletrophoresis, thiab nyob rau hauv protein purification nyob rau hauv chromatography. |
