kev siv
4-Morpholdhaethansulfonic acid (mes) yog ib qho kev siv tsis sib haum hauv biochemical kev tshawb fawb thiab molecular biology. Nov yog qee qhov tseem ceeb ntsiab lus txog MES:
Tsis yog:MES siv los ua tus neeg sawv cev buffering los tswj cov pH tas li hauv roj ntsha thiab tshuaj sim. Nws muaj pka ntawm kwv yees li ntawm 6.15, ua kom nws ua tau zoo rau kev tswj hwm tus pH hauv cov 5.5 rau 6.7.
Stability:Mes muaj qhov ruaj khov nyob rau ntau qhov kub thiab txias thiab yog tshwj xeeb rau kev tswj xyuas hauv lub cev ntau yam. Nws tsis tshua muaj kev cuam tshuam los ntawm qhov kub hloov pauv piv rau lwm tus tsis zoo li phosphate buffers.
Protein thiab enzyme kawm:Mes yog feem ntau siv nyob rau hauv cov protein purification, enzyme cia, thiab lwm yam kev sim biochemical uas muaj cov protein thiab cov enzymes. Nws cov UV qis dua ntawm cov wavelengths ua rau nws haum rau kev ntsuas spectrophotometric ntsuas.
Cellure Culture:Leejis tseem siv nyob rau hauv qee cov kab lis kev cai xov tooj ntawm tes los pab ua kom ruaj khov v rau txoj kev loj hlob thiab txij nkawm ntawm ib qho ntawm cov hom kab.
phua:MES yog qhov zoo tshaj plaws ntawm p qhov tseem ceeb nyob ib ncig 6.0. Nws yog qhov tsawg dua rau cov ntawv thov uas xav tau cov kua qaub ntau dua lossis cov lus qhia ua kom zoo nrog cov lus qhia, nws yuav tsum tau ua raws li cov lus siv tsim nyog thiab ua haujlwm rau cov kev siv tshwj xeeb.
Nws tseem yog ib qho tseem ceeb kom nco ntsoov tias cov niam tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab kev ntsuas kev ua kom zoo thiab kev ntsuas kev nyab xeeb yuav tsum tau ua thaum tuav cov compress no.
