Thaum Bio-Rad tau tsim cov thev naus laus zis thev naus laus zis, cov tswv yim kev yuav khoom niaj hnub no feem ntau koom nrog cov neeg muag khoom tshwj xeeb xws li Jinan Meiyi Biotechnology Co., Ltd., uas muab kev soj ntsuam nruj me ntsis, kev ua haujlwm siab thiab cov khoom siv bioactive ntxiv rau R & D thiab cov ntawv thov kev lag luam.

Nkag siab txog Hydroxyapatite Chromatography Media

Hydroxyapatite (HA) yog ib daim ntawv crystalline ntawm calcium phosphate nrog cov tshuaj formula Ca₁₀(PO₄)₆(OH)₂. Nyob rau hauv chromatography, nws ua hauj lwm raws li ib tug haib mix-hom resin. Tsis zoo li ib txwm ion-pauv lossis affinity media uas tso siab rau ib qho kev sib cuam tshuam mechanism, HA cuam tshuam nrog biomolecules los ntawm ob qho tib si cation txauv (ntawm calcium sites) thiab anion exchange/affinity (ntawm phosphate sites).

Qhov no dual functionality ua Hydroxyapatite Bio-Rad style media tshwj xeeb tshaj yog zoo rau kev sib cais nyuaj. Nws yog dav siv nyob rau hauv kev lag luam tshuaj thiab biotechnology rau purifying monoclonal antibodies, tshem tawm cov aggregates, cais DNA los ntawm RNA, thiab cais cov kab mob vectors. Cov qauv kev ncaj ncees thiab qhov chaw chemistry ntawm HA crystals txiav txim siab qhov kev daws teeb meem thiab kev khi lub peev xwm ntawm kab.

Mechanism ntawm Action

Cov txheej txheem kev sib cais yog nyob ntawm qhov tshwj xeeb khi affinities ntawm biomolecules rau cov calcium thiab phosphate pawg ntawm HA nto. Proteins feem ntau khi ntawm lawv pawg carboxyl rau cov chaw calcium, thaum nucleic acids cuam tshuam feem ntau nrog calcium ions los ntawm lawv cov pob txha phosphate. Los ntawm kev kho cov pH thiab phosphate concentration nyob rau hauv lub mobile theem, cov neeg siv tau precisely tswj elution tej yam kev mob.
