Celična kultura je pomembna in pogosto uporabljena tehnika v raziskovalnih metodah celične biologije. S celično kulturo je mogoče pridobiti veliko število celic in s celično kulturo preučevati transdukcijo celičnega signala, celični anabolizem, rast in proliferacijo celic. V obsežni celični kulturi je cell factory učinkovit in pogosto uporabljen potrošni material celične kulture.
celična tovarna je sestavljena iz ene ali več plasti, običajne so 1 sloj, 2 plasti, 5 plasti , 10 plasti, 40 plasti itd. Plasti so povezane s posebnim lepilnim postopkom, ki zagotavlja trdnost izdelka. Da bi izboljšali hidrofilnost površine posode in jo naredili bolj primerno za rast in razmnoževanje celic, bo ta potrošni material podvržen posebni površinski obdelavi za uvedbo hidrofilnih skupin na hidrofobno površino, da se poveča oprijem celic in olajša celice z nizko stopnjo adhezijske lastnosti se držijo stene.
Celična tovarna je primerna predvsem za kulturo različnih adherentnih celic, kot so celice Vero, celice HEK 293, celice CAR-T, MRC5, celice CEF, prašičji alveolarni makrofagi, mielom celice, celice DF-1, celice ST, celice PK15, celice Marc145 in druge adherentne celice. Primeren je tudi za statično kulturo suspenzijskih celic, kot so celice CHO, celice žuželk, celice BHK21 in celice MDCK.
Uporaba celičnih tovarn za obsežno celično kulturo lahko zmanjša prostor, prihrani delovno silo in poveča območje kulture, medtem ko zmanjšanje možnosti kontaminacije celic. Široko se uporablja pri razvoju cepiv in industrijski proizvodnji celic.
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.
