Media bottlehuwa kontenitur għall-ħażna tas-serum, li ġeneralment huwa magħmul minn PET jew PETG materjal permezz ta 'proċess ta' nfiħ ta 'stirad ta' injezzjoni. Il-medju huwa n-nutrijent meħtieġ għat-tkabbir taċ-ċelluli. Skont is-sors tiegħu, huwa maqsum f'medju sintetiku u medju naturali, li t-tnejn jistgħu jinħażnu fi fliexken tal-midja.
Medju naturali:
Il-mezz naturali l-aktar użat komunement huwa serum, bażikament serum tal-għoġol. Is-serum fih varjetà ta 'fatturi ta' tkabbir taċ-ċelluli, fatturi li jippromwovu l-adeżjoni u s-sustanzi multi-attivi tagħhom. Meta jintuża flimkien ma 'medja sintetika, iċ-ċelloli jistgħu jipproliferaw u jikbru bla xkiel. Is-serum jeħtieġ li jinħażen fi fliexken tal-midja speċjali f'-5°C sa -20°C.
Medju sintetiku:
Medju sintetiku huwa fformulat b'mod strett skond it-tip u l-kwantità ta 'sustanzi meħtieġa miċ-ċelloli. Hemm ħafna tipi u komponenti magħrufa, li jiffaċilita l-kontroll tal-kundizzjonijiet sperimentali. Fih karboidrati, aċidi amminiċi, lipidi, melħ inorganiku, vitamini, oligoelementi u fatturi tat-tkabbir taċ-ċelluli. Madankollu, meta mqabbel mal-medju naturali, xi komponenti naturali mhux magħrufa ma jistgħux jiġu sostitwiti b'komponenti kimiċi magħrufa. Għalhekk, il-mezz sintetiku bażiku użat fil-kultura taċ-ċelluli għandu jżid ukoll ċertu ammont ta 'komponenti medji naturali biex jegħleb il-kultura sintetika. L-aktar prattika komuni hija li żżid is-serum tal-għoġol.
Il-forma tal-flixkun tal-midja hija kwadra, faċli biex tinqabad, reżistenti għall-biċċa l-kbira tal-korrużjoni tal-aċidu u tal-alkali, it-temperatura tal-fraġilità hija -70 °C, u għad għandha ċerta toughness fi -30 °C. Huwa kontenitur tal-ippakkjar tajjeb, kemm midja naturali kif ukoll sintetika jistgħu jinħażnu fi flixkun tal-midja.
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.
