ko'p qatlamli hujayra madaniyati sarflanadigan material bo'lib, u asosan sanoat ommaviy ishlab chiqarishda, laboratoriya operatsiyalarida va keng ko'lamli hujayra madaniyatida qo'llaniladi va yopishgan hujayralar uchun ideal tanlovdir. Ushbu turdagi sarf materiallarini tanlashda biz asosiy omilga e'tibor beramiz, ya'ni sirt TC bilan ishlov berish, nima uchun u ushbu maxsus ishlovdan o'tishi kerak?Hujayralar ikki turga bo'linishi mumkin: yopishqoq turli o'sish usullariga ko'ra hujayralar va suspenziya hujayralari. Suspenziya xujayralari o'sishi uchun tayanchga bog'lanishi shart emas va ular madaniy muhitda suspenziyada o'sishi mumkin. Yopishqoq hujayralar o'sish yuzasiga ega bo'lishi kerak, ular o'sishi uchun biriktirilishi mumkin va faqat gidrofil qattiq interfeys hujayralarning biriktirilishiga imkon beradi. hujayra fabrikasi
Hujayralar zavodi asosan yopishtiruvchi hujayralar madaniyati uchun ishlatiladi, u in'ektsion kalıplama orqali qayta ishlanadi. shaffof polistirol (PS) xom ashyosi. Polimer material sifatida PS yaxshi quvvat va plastisiyaga ega va toksikligi yo'q va bir martalik hujayra madaniyati sarf materiallari uchun afzal qilingan materialga aylandi. Biroq, PS ning yuzasi hidrofobikdir, bu o'zi yopishgan hujayralarning o'sishiga yordam bermaydi. Hujayralarning yopishish ko'rsatkichlarini oshirish uchun sirtni modifikatsiyalash bilan ishlov berish va hujayralarni yaxshiroq o'sishi uchun gidrofil guruhlarni kiritish kerak.
Xulosa qilib aytganda, hujayra zavod yuzasida TC bilan ishlov berishning maqsadi hujayraning zavod yuzasiga moslashishdir. yopishgan hujayralarning o'sishi. Suspension hujayra madaniyati uchun ishlatiladigan sarf materiallari, albatta, bunday maxsus ishlov berilgan idishlarni talab qilmaydi, lekin sirt TC bilan ishlov berishdan keyin sarflanadigan materiallar, odatda, suspenziya hujayralari madaniyati uchun ham mos keladi.
In summary, the purpose of TC treatment on the cell factory surface is to adapt to the growth of adherent cells. The consumables used for suspension cell culture do not necessarily require such specially treated vessels, but the consumables after surface TC treatment are generally also suitable for the culture of suspension cells.
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.
