Farmatsevtika sanoatining jadal rivojlanishi hujayra madaniyati texnologiyasiga o'z ambitsiyalarini rivojlantirishga imkon berdi. hujayra fabrikalari kabi hujayra madaniyati sarf materiallari yordamida vaktsinalar, monoklonal antikorlar yoki farmatsevtika sanoati kabi sanoat ommaviy ishlab chiqarishda muhim rol o'ynaydi. To'g'ri foydalanish hujayra madaniyatini yanada samarali ishlashiga olib kelishi mumkin, shuning uchun hujayra zavodlaridan qanday foydalanish kerak?
Hujayra zavodidan foydalanish muayyan usullar va bosqichlarga amal qilishi kerak. Noto'g'ri operatsiya keyingi hujayra madaniyatiga ta'sir qiladi. Hujayra zavodidan foydalanish bosqichlari quyidagicha:
1. Hujayra zavodiga kerakli miqdordagi hujayra suspenziyasini quyish orqali qo'shing. Har bir qatlam uchun tavsiya etilgan hajm 200ML.
2. Hujayra suspenziyasini qo'shgandan so'ng, hujayra zavodini yon tomonida, suyuqlik qo'shiladigan porti sizga qaragan holda ushlab turing va suyuqlik har bir qatlamga teng taqsimlanishi uchun bir muddat muvozanatni saqlang.
3. Suyuqlik to'ldirish porti yuqoriga qaratib turishi uchun soat sohasi farqli o'laroq 90 daraja aylantiring va uni bir muddat tursin, madaniy muhit avtomatik ravishda va har bir qatlamga teng taqsimlanadi.
4. Suyuqlik kirish joyining bir tomonini ikki qo'lingiz bilan ushlang va hujayra zavodini sekin pastga qo'ying va gorizontal ravishda joylashtiring.
5. Suspenziyani o'zaro faoliyat usuli yordamida aralashtiramiz va keyin hujayra zavodini inkubatsiya uchun hujayra inkubatoriga ohista o'tkazing.
6. Inkubatsiyadan so'ng madaniy muhitni to'g'ridan-to'g'ri yig'ish idishiga quying.
7. Avval PBS bilan yuving (2-4-bosqichlarni bajaring), hujayra hazm qilish eritmasini qo'shing (har bir qatlamga ≥ 15ML/qatlam hazm qilish uchun eritma qo'shish tavsiya etiladi), 2-4-bosqichlarni takrorlang va 2 daqiqaga qoldiring (hujayra hazm qilish shartlariga qarab). ) Albatta).
8. Kerakli miqdorda hazm qilishni to'xtatuvchi eritma qo'shing, yaxshilab aralashtiring va hujayra suspenziyasini yig'ish idishiga quying.
Hujayra madaniyati juda nozik ish. hujayra zavodlari ni tanlashdan tortib, har bir bosqichning operatsiya bosqichlarigacha, hujayra madaniyati ishining muammosiz rivojlanishini ta'minlash uchun to'g'ri usuldan foydalanish juda muhimdir.
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.
