Mae'r Mae'r ffatri gell yn cael ei ddefnyddio'n bennaf ar gyfer diwylliant celloedd ymlynol, sy'n cael ei brosesu trwy fowldio chwistrellu o deunyddiau crai polystyren tryloyw (PS). Fel deunydd polymer, mae gan PS gryfder a phlastigrwydd da, ac nid oes ganddo wenwyndra, ac mae wedi dod yn ddeunydd dewisol ar gyfer nwyddau traul diwylliant celloedd tafladwy. Fodd bynnag, mae wyneb PS yn hydroffobig, nad yw ei hun yn ffafriol i dwf celloedd ymlynol. Er mwyn gwella perfformiad ymlyniad celloedd, mae angen cael triniaeth addasu arwyneb a chyflwyno grwpiau hydroffilig i ganiatáu i gelloedd dyfu'n well. yn ddiwylliant celloedd aml-haenog traul, a ddefnyddir yn bennaf mewn cynhyrchu màs diwydiannol, gweithrediadau labordy a diwylliant celloedd ar raddfa fawr, ac mae'n ddewis delfrydol ar gyfer celloedd ymlynol. Wrth ddewis y math hwn o nwyddau traul, byddwn yn rhoi sylw i ffactor allweddol, sef y driniaeth TC arwyneb, pam mae'n rhaid iddo gael y driniaeth arbennig hon? celloedd a chelloedd crog yn ôl gwahanol ddulliau twf. Nid oes angen i gelloedd crog fod yn gysylltiedig â chymorth i dyfu, a gallant dyfu mewn ataliad mewn cyfrwng diwylliant. Rhaid bod gan gelloedd ymlynol arwyneb twf y gallant lynu ato i dyfu, a dim ond rhyngwyneb solet hydroffilig all ganiatáu i gelloedd atodi.
I grynhoi, pwrpas triniaeth TC ar wyneb y ffatri gell yw addasu i'r twf celloedd ymlynol. Nid yw'r nwyddau traul a ddefnyddir ar gyfer meithriniad celloedd crog o reidrwydd yn gofyn am longau sydd wedi'u trin yn arbennig, ond mae'r nwyddau traul ar ôl triniaeth TC arwyneb yn gyffredinol hefyd yn addas ar gyfer diwylliant celloedd crog.
The cell factory is mainly used for the culture of adherent cells, which is processed by injection molding of transparent polystyrene (PS) raw materials. As a polymer material, PS has good strength and plasticity, and has no toxicity, and has become the preferred material for disposable cell culture consumables. However, the surface of PS is hydrophobic, which itself is not conducive to the growth of adherent cells. In order to enhance the adherence performance of cells, it is necessary to undergo surface modification treatment and introduce hydrophilic groups to allow cells to grow better.
In summary, the purpose of TC treatment on the cell factory surface is to adapt to the growth of adherent cells. The consumables used for suspension cell culture do not necessarily require such specially treated vessels, but the consumables after surface TC treatment are generally also suitable for the culture of suspension cells.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
