Hujayra fabrikasikeng ko'lamli hujayra madaniyati uchun mos bo'lgan ko'p qatlamli hujayra madaniyati sarflanadi. Hujayra madaniyati uchun o'ziga xos muhitdan tashqari, ovqat hazm qilish shirasi ham muhim yechim hisoblanadi.
To'qima hujayralarining in vitro madaniyatida va birlamchi hujayra madaniyatida to'qima hujayralarining tarqalishi (to'qima bloki tayyorlanadi) bitta hujayra suspenziyasiga) shuningdek, subkulturada yopishgan o'sayotgan hujayralarni hazm qilish va tarqatishda to'qima hujayralari hazm qilish eritmasidan foydalanish kerak. Hujayra zavodi madaniyati texnologiyasida ishlatiladigan hazm qilish eritmasi asosan tripsin, EDTA va boshqalar
Hujayra membranasining asosiy komponentlari va hujayralar orasidagi yopishish lipoproteinlar va polisaxaridlardir. Tripsin tarkibidagi tripsin oqsillarni peptonlarga aylantira oladi va pankreatik lipaz yog'ni glitserin va yog' kislotalariga parchalaydi va shu bilan hujayralarni ajratadi. Hujayralar parchalanadi. Ovqat hazm qilish eritmasining vazifasi, asosan, hujayralararo oqsillarni (masalan, hujayradan tashqari matritsa) gidrolizlash, to'qima yoki yopishgan hujayralarni bitta hujayralarga tarqatish va keyingi tajribalar uchun hujayra suspenziyasini yaratishdir.
Ozlash fermentlari muhim rol o'ynaydi. hujayra zavodlari madaniyatida, ammo shuni ta'kidlash kerakki, turli hujayralar oshqozon osti bezi fermentlariga turli xil javoblarga ega. PH qiymati 8,0 va harorat 37 ° C bo'lsa, oshqozon osti bezi fermenti eritmasi eng kuchli ta'sirga ega. , Hujayralarning yopishishi va o'sishiga ta'sir qiluvchi ortiqcha hazm bo'lishining oldini olish uchun foydalanish paytida konsentratsiya, harorat va vaqt yaxshi nazorat qilinishi kerak.
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.
