Kunezinhlobo eziningi zamaseli. Ngokombono wezindlela zesiko, zihlukaniswa kakhulu zibe izinhlobo ezimbili: amaseli abambelelayo namaseli amisiwe. I-cell culture flasks ingasetshenziselwa isiko lamaseli anamathelayo namaseli amisiwe. Umehluko ukuthi uma kusetshenziselwa ukukhulisa amaseli anamathelayo, ingaphezulu lezinto ezidlekayo lidinga ukuphathwa nge-surface TC.
Okwehlukile kumaseli amisiwe, ukukhula kwamaseli anamathelayo kumele kube nendawo yokusekela okungaba okunamathiselwe kuwo, namaseli angakhula futhi akhiqize kabusha kule ndawo ngokuthembela ezintweni ezinamathiselwe ezifihliwe ngokwazo noma ezihlinzekwe kusikompilo. Esikhathini esedlule, izinto ezisetshenziswayo zesiko lamaseli zazivame ukwenziwa ngengilazi, okuyi-hydrophilic, ngakho-ke indawo engaphezulu ayidingi ukwelashwa okukhethekile. Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, izinto ezahlukahlukene ze-polymer ziye zashintsha kancane kancane izinto zengilazi futhi zaba yizinto ezinhle zokucubungula izinto ezisetshenziswayo zesiko lamaseli. Ukuze kuqinisekiswe ukuthi amaseli anamathelayo angaxhunywa kahle ebusweni bezinto ezisetshenziswayo, ingaphezulu leflask yesikwele yesiko leseli lidinga ukuguqulwa ngokukhethekile ukuze kwethulwe izici ze-hydrophilic ebusweni ukuze zivumelane nokukhula nokukhiqizwa kabusha kwamaseli anamathelayo. .
TC Igama eligcwele: Ukwelashwa kwezicubu zomzimba, ukwelashwa kwe-TC kusho ukuthi ingaphezulu lomkhumbi lishintshiwe ukuze lifanele ukutshalwa kwamaseli abambelelayo. Amaseli akhula ngokumiswa awadingi izitsha ezinjalo eziphathwe ngokukhethekile. Kodwa-ke, izitsha zamaseli ngemva kokwelashwa kokulungiswa kwendawo ngokuvamile zifanelekela isiko lamaseli amisiwe.
Ukwelashwa kwe-TC kuyinqubo ebalulekile amaflaski e-cell culture, izimboni zamaseli nokunye okusebenzisekayo kwamaseli okunamathelayo. Kube yisihluthulelo sokuqinisekisa ukukhula okuvamile nokukhiqizwa kabusha kwamangqamuzana futhi izodlala indima ebaluleke kakhulu emkhakheni wesayensi yempilo.
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.
