Hujayra madaniyati aseptik ish texnologiyasining bir turi bo'lib, ish muhiti va sharoitlari mikroblar bilan ifloslanishdan xoli bo'lishi va boshqa zararli omillar ta'siriga uchramasligi kerak. Hujayra madaniyati kolbalari hujayra tajribalarida tez-tez ishlatiladigan sarf materiallari. DNK va RNase yo'q sarf materiallari uchun asosiy talablar. Xo'sh, qanday qilib hujayra madaniyati kolbalari DNK va RNazsiz bo'lishi mumkin?
Hujayra madaniyati xonasi va dizayn printsipi mikrobial ifloslanish va zararli omillarning oldini olish va toza ish muhiti, toza havo, quruqlik va tutun yo'q. Hujayra madaniyati flakonlari va boshqa sarf materiallari ishlab chiqarish ustaxonalari 100 000 darajali GMP ustaxonalari va inson dori vositalarini ishlab chiqarish ustaxonalari ham 100 000 darajali. Shuning uchun bunday sharoitda ishlab chiqarilgan mahsulotlar odatda DNK va RNK fermentlaridan xoli bo'ladi. Tayyor mahsulot chiqqandan keyin esa mahsulotni sinash uchun DNK va RNK degradatsiyasi tajribalaridan ham foydalanadi va faqat malakali mahsulotlar zavodni tark etishi mumkin.
Malakali hujayra madaniyati kolbalari hujayra oʻsishini taʼminlovchi asosiy omil hisoblanadi. Hujayra madaniyatida ishlatiladigan sarf materiallari va idishlarni o'z vaqtida avtoklavga solib, sterilizatsiya qilinganidan keyin bir haftadan ko'proq vaqt davomida ishlatilmasa, ularni qayta sterilizatsiya qilish kerak. Tayyorlangan to'liq vosita, pankreatin, PBS va boshqalar eng yaxshi bir hafta ichida ishlatiladi. Shu bilan birga, har kuni hujayra holatini tekshiring. Hujayra xonasida yurishni kamaytirish va iloji boricha kamroq gapirish kerak. Agar siz yo'talsangiz yoki aksirsangiz, orqangizni o'ta toza stolga o'girganingizga ishonch hosil qiling. Laboratoriyaning atrof-muhit sanitariyasini saqlang va hujayra tajribasining muvaffaqiyati uchun poydevor qo'ying.
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.
