Bħala konsumabbli komuni għall-kultura taċ-ċelluli fuq skala kbira, fabbriki taċ-ċelluli għandhom rwol importanti fl-iżvilupp tal-vaċċini, bijofarmaċewtiċi u oqsma oħra. Il-kultura taċ-ċelluli hija kompitu speċjali. Wara li jsiru l-preparazzjonijiet kollha, huwa meħtieġ li taqbad l-istat tat-tkabbir taċ-ċelluli fil-ħin biex tagħmel aġġustamenti għal kull xogħol.
Skond iż-żona tal-kultura, il-fabbrika taċ-ċelluli tikkonsisti minn saff wieħed jew aktar bħal 1 saff, 2 saffi, 5 saffi, 10 saffi, u 40 saff. L-osservazzjoni tal-istat tat-tkabbir taċ-ċelloli ġeneralment teħtieġ mikroskopju maqlub, iżda dan l-istrument ġeneralment biss Huwa adattat għall-osservazzjoni ta '1-10 saffi ta' fabbriki taċ-ċelloli, u jista 'josserva t-tkabbir ta' 1 u 2 saffi. It-tieni saff t'isfel jista 'biss josserva l-uniformità taċ-ċelloli tiegħu, u mhuwiex adattat għal erbgħin saff.
Jekk trid tosserva l-istat tat-tkabbir taċ-ċelloli f'aktar saffi ta' fabbriki taċ-ċelloli, għandek bżonn tuża mikroskopji ddisinjati apposta biex josserva fabbriki taċ-ċelluli. Strumenti bħal dawn ġeneralment ikollhom lentijiet f'żewġ direzzjonijiet: osservazzjoni tal-ġenb u osservazzjoni tal-qiegħ. Is-sistema tista 'tikkalkula d-daqs taċ-ċellula u d-densità tat-tkabbir, u tista' tosserva l-istat taċ-ċelloli fis-saffi kollha tal-fabbriki taċ-ċelloli. . Jekk l-istat tat-tkabbir taċ-ċelluli huwa fqir, il-kontorn taċ-ċellula se jitjieb, l-indiċi refrattiv taċ-ċelluli jiddgħajjef, vakuoli, qtar tal-lipidi u sustanzi granulari oħra jidhru fiċ-ċitoplasma taċ-ċellula, id-distakk bejn iċ-ċelloli se jiżdied, il-forma tkun irregolari , u anke ċ-ċelloli oriġinali jintilfu. Karatteristiċi, li jirriżultaw fi jinxtorob tond u twaqqigħ, u xi kultant flocs filamentous jidhru fuq u madwar il-wiċċ taċ-ċellula.
Meta tosserva ċ-ċelloli fil-fabbrika taċ-ċelluli, agħti attenzjoni għall-kunċett ta 'sterilità. Il-movimenti għandhom ikunu ħfief, jevitaw xokkijiet vjolenti, il-ħin ta 'osservazzjoni m'għandux ikun twil wisq, u n-numru ta' osservazzjonijiet m'għandux ikun frekwenti wisq, sabiex ma jaffettwax it-tkabbir taċ-ċelluli.
When observing the cells in the cell factory, pay attention to the concept of sterility. The movements should be light, avoid violent shocks, the observation time should not be too long, and the number of observations should not be too frequent, so as not to affect the cell growth.
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.
