Cov Ntawv Thov
1. Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Biochemical
Tus neeg sawv cev buffering nyob rau hauv cell kev cai thiab molecular biology:
Tswj hwm cov hauv paus ruaj khov, tshwj xeeb tshaj yog nyob rau hauv lub cev muaj kev sib ze ze rau pH 7.4
Ib txwm nyob rau hauv cov niam cell kab lis kev cai xov xwm, protein purification, thiab enzyme cia
2. Cell Culture thiab cov ntaub so ntswg tsim
Siv los ua kom ruaj khov hluav taws xob hauv xov tooj ntawm tes yam tsis muaj qhov xav tau kev sib koom ua ke (piv txwv li, bicarbonate buffers).
Qhov tseem ceeb hauv cov tshuab rhiab uas yog qhov tseeb PT yog qhov tseem ceeb, xws li qia hlwb lossis neuron haiv neeg.
3. Protein thiab enzyme stabilization
Siv hauv cov protein crystallography, enzyme cia, thiab biochemical cia los tswj cov qauv protein thiab muaj nuj nqi.
4. Kev kuaj mob cov khoom siv thiab cov biosensors
Muaj nyob rau hauv chaw kuaj mob kuaj mob, pCR cov khoom siv, thiab biosensor matrices los xyuas kom meej cov txiaj ntsig rov qab ua dua tshiab nyob ze-physicaliological.
5. Electrophoresis thiab chromatography
Cov kev pab hepes raws li siv nyob rau hauv cov capillary Electrophoresis, Gel Electrophoresis, thiab HPLC rau Biomolecule sib cais hauv Ph.
6. Kev Tshawb Fawb Kev Kho Mob thiab Tshuaj Kho Mob
Ua haujlwm hauv cov yeeb tshuaj ua haujlwm thiab cov zaub mov xa tawm qhov twg physiological p kev ruaj khov yog qhov tseem ceeb rau kev siv tshuaj solubility thiab efficacy.
Cov txiaj ntsig
1. Zoo heev p kev ruaj khov
Qhov kub thiab txias thiab kub thiab txias thiab kub siab. Kev pab tu siab, ua rau nws zoo dua rau kev sim ntev thiab paub meej.
2. Biocompatibility
Tsis muaj tshuaj lom rau cov hlwb thiab tsis cuam tshuam nrog cov roj ntsha muaj kev pheej hmoo ntau, ua rau nws zoo tagnrho rau hauv Vitro thiab Vivo kev tshawb fawb.
3. Co₂-Independent Buffering
Tsis zoo li Bricarbonate Buffers, hepes tsis tas yuav muaj kev ntsuas pa taws, tso cai ntau sim sim.
4. Tsawg hlau ion Binding
Muaj tsawg affinity rau cov neeg sib txawv (piv txwv, mg²⁺, tsis txhob muaj kev cuam tshuam nrog enzymatic cov tshuaj tiv thaiv lossis ion-rhiab.
5. Pob tshab rau UV thiab Pom Lub Teeb
Tsis nqus tau qhov tseem ceeb hauv UV-pom Spectrum, ua rau nws haum rau SpectrophoTometric nco thiab kev siv duab.
