kvadrat va keng darboğazli dizayni bilan iste'mol qilinadigan maxsus hujayra madaniyati. Turli xil foydalanish ehtiyojlariga ko'ra, ushbu sarflanadigan material eksperimentchilarning turli ehtiyojlarini qondirish uchun 25cm2, 75cm2, 175cm2, 225cm2 va boshqa xususiyatlarga bo'linadi.Kichik o'lcham: hujayraning o'lchami hujayra madaniyati kolbasining madaniyat maydoni. 25 sm2 va 75 sm2 shishalar asosan hujayralarni tiklash va kichik hajmdagi kengaytirish uchun ishlatiladi. Hujayra reanimatsiyasi biologik atama bo'lib, o'sishni tiklash uchun suyuq azotda yoki muzlatgichda -70 ° C da muzlatilgan hujayralarni qayta o'stirish jarayonini anglatadi. Hujayra kengayishi mavjud hujayralarni ko'paytirish va qayta etishtirishni nazarda tutadi. hujayra madaniyati kolbasi
Katta o'lcham: 175cm2 va 225cm asosan o'rta miqyosdagi hujayra madaniyati va eukaryotik oqsillarni ifodalash uchun mos keladi. Hujayra madaniyati uchun foydalanilganda, u odatda yopishgan hujayralarga ishora qiladi va ba'zi suspenziya hujayralari ham ushbu sarf materialidan foydalanadi. Eukaryotik oqsillarni ifodalash so'nggi yillarda rekombinant oqsillarni ifodalash uchun keng tarqalgan usuldir. Prokaryotik oqsillarni ifodalash tizimlarida etishmayotgan ba'zi funktsiyalarni to'ldiradi. Masalan, u eukaryotik ekspressiya paytida barqaror disulfid bog'larini hosil qilishi mumkin. Proteinni to'g'ri o'zgartiring, aks ettirilgan protein parchalanish yoki inklyuziya jismlarini hosil qilish o'rniga tabiiy faollikni oshirish; eukaryotik ekspresyon tizimidan foydalanish odamlarning genlarini tadqiq qilish va giyohvand moddalarni tadqiq qilish jarayonini tezlashtirib, yuqori samarali ekspressiyani keltirib chiqarishi mumkin.

dan foydalanishdir. Qaysi jihat ishlatilmasin, DNazsiz, RNazsiz va pirojensiz kabi asosiy talablar bir xil bo'lib, bu ham hujayra o'sishi uchun asosiy talab hisoblanadi.cell culture flaskshujayra madaniyati kolbalari
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.
