Media bottleyn gynhwysydd ar gyfer storio serwm, sy'n cael ei wneud yn gyffredinol o PET neu PETG deunydd trwy broses chwythu ymestyn chwistrelliad. Y cyfrwng yw'r maetholion sydd eu hangen ar gyfer twf celloedd. Yn ôl ei ffynhonnell, mae wedi'i rannu'n gyfrwng synthetig a chyfrwng naturiol, a gellir storio'r ddau mewn poteli cyfryngau.
cyfrwng naturiol:
Y cyfrwng naturiol a ddefnyddir amlaf yw serwm, yn y bôn serwm llo. Mae serwm yn cynnwys amrywiaeth o ffactorau twf celloedd, ffactorau sy'n hyrwyddo adlyniad a'u sylweddau aml-weithredol. Pan gânt eu defnyddio mewn cyfuniad â chyfrwng synthetig, gall celloedd amlhau a thyfu'n esmwyth. Mae angen storio serwm mewn poteli cyfryngau arbennig ar -5 ° C i -20 ° C.
cyfrwng synthetig:
Mae cyfrwng synthetig wedi'i lunio'n llym yn ôl y math a maint y sylweddau sydd eu hangen ar gelloedd. Mae yna lawer o fathau a chydrannau hysbys, sy'n hwyluso rheolaeth amodau arbrofol. Mae'n cynnwys carbohydradau, asidau amino, lipidau, halwynau anorganig, fitaminau, elfennau hybrin a ffactorau twf celloedd. Fodd bynnag, o gymharu â'r cyfrwng naturiol, ni ellir disodli rhai cydrannau anhysbys naturiol gan gydrannau cemegol hysbys. Felly, rhaid i'r cyfrwng synthetig sylfaenol a ddefnyddir mewn diwylliant celloedd hefyd ychwanegu rhywfaint o gydrannau cyfrwng naturiol i oresgyn y diwylliant synthetig. Yr arfer mwyaf cyffredin yw ychwanegu serum llo. ar -30 °C. Mae'n gynhwysydd pecynnu da, gellir storio cyfryngau naturiol a synthetig mewn potel cyfryngau.
The shape of the media bottle is square, easy to grasp, resistant to most acid and alkali corrosion, the embrittlement temperature is -70 °C, and it still has a certain toughness at -30 °C. It is a good packaging container, both natural and synthetic media can be stored in media bottle.
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.
