Vim li cas Tissue Culture Treated (TC Treated) xav tau rau cov khoom siv ntawm tes
Muaj ntau hom cell, uas tuaj yeem muab faib ua cov hlwb adherent thiab suspension cells nyob rau hauv cov nqe lus ntawm kab lis kev cai Txoj kev Suspended cells yog cov hlwb uas loj hlob ntawm nws tus kheej ntawm qhov kev txhawb nqa, thiab loj hlob nyob rau hauv kev ncua nyob rau hauv kab lis kev cai nruab nrab, xws li lymphocytes Adherent cells. yog cov hlwb adherent, uas txhais tau hais tias kev loj hlob ntawm cov hlwb yuav tsum muaj qhov chaw txhawb nqa.Lawv tsuas tuaj yeem loj hlob thiab tsim tawm ntawm qhov chaw no los ntawm kev cia siab rau cov khoom adhesion secreted los ntawm lawv tus kheej los yog muab rau hauv kab lis kev cai nruab nrab.Feem ntau cov tsiaj txhu muaj nyob rau hauv cov kab mob sib txuas
Yav dhau los, feem ntau ntawm cov kab lis kev cai ntawm cov khoom siv hauv kev lag luam tau ua los ntawm iav, uas yog hydrophilic, yog li qhov saum npoo tsis xav tau kev kho tshwj xeeb Txawm li cas los xij, hauv cov txheej txheem siv tiag tiag, muaj qee qhov tsis zoo xws li kev tsis huv thiab yooj yim rau paug cov qauv nrog. Kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, ntau yam khoom siv polymer (xws li polystyrene PS) tau maj mam hloov cov ntaub ntawv iav thiab dhau los ua cov ntaub ntawv tseem ceeb rau cov khoom siv ntawm tes.
Polystyrene yog amorphous random polymer nrog pob tshab.Nws cov khoom muaj qhov pom tseeb heev, nrog rau kev xa tawm ntau dua 90%, uas yog qhov tsim nyog rau kev soj ntsuam cov kab lis kev cai hauv lub xeev ntawm lub tshuab tsom.Tsis tas li ntawd, nws muaj qhov zoo ntawm cov xim yooj yim, ua haujlwm zoo fluidity, zoo rigidity thiab zoo tshuaj corrosion kuj.Txawm li cas los xij, qhov chaw ntawm polystyrene yog hydrophobic.Txhawm rau kom ntseeg tau tias cov kab mob sib txuas tuaj yeem txuas rau saum npoo ntawm cov khoom siv tau zoo, qhov chaw ntawm cov khoom siv rau cov kab lis kev cai ntawm tes yuav tsum tau txais kev kho tshwj xeeb.Hydrophilic yam yog qhia nyob rau saum npoo kom hloov mus rau kev loj hlob thiab kev loj hlob ntawm cov hlwb adherent.Qhov kev kho no hu ua TC kho.TC kho yog muaj feem xyuam rau cell kab lis kev cai tais diav, cell kab lis kev cai daim hlau, cell nce toj daim hlau, cell kab lis kev cai fwj, thiab lwm yam Feem ntau, plasma nto kho cov cuab yeej yog siv los ua kom tiav TC kho ntawm cell kab lis kev cai tais diav.
Cov yam ntxwv ntawm cell kab lis kev cai tais tom qab TC kho:
1. Ua ntej ntxuav cov khoom nto: O2 plasma tuaj yeem nqus cov khoom me me thiab lwm cov pa phem uas txuas rau ntawm cov khoom nto, thiab kos cov roj sib xyaw tawm ntawm lub tshuab nqus tsev los ntawm lub tshuab nqus tsev twj kom ua tiav cov nyhuv ua ntej.
2. Txo qhov nro ntawm cov khoom, kom cov dej sib cuag lub kaum sab xis ntawm cov khoom raug txo kom tsawg, thiab phim lub zog ionization thiab concentration, kom cov dej sib cuag lub kaum sab xis ntawm cov khoom nto WCA <10 °.
3.O2 plasma yuav hnov mob chemically ntawm cov khoom nto, thiab ntau pab pawg ua haujlwm tuaj yeem ntxiv rau cov khoom nto, xws li hydroxyl (- OH), carboxyl (- COOH), carbonyl (- CO -), hydroperoxy (- OOH), thiab lwm yam. Cov pab pawg ua haujlwm nquag no tuaj yeem txhim kho kab lis kev cai nrawm thiab kev ua haujlwm thaum lub sijhawm kab lis kev cai ntawm tes.
