Hujayra madaniyati texnologiyasining rivojlanishi hozirgacha juda etuk. Hujayra o'sishi atrof-muhit, harorat, osmotik bosim, pH qiymati va boshqalar kabi turli talablarga javob berishi kerak. Turli xil sintetik muhitda asosiy oziq moddalar bilan ta'minlashdan tashqari, turli hujayralar va turli madaniyat maqsadlariga moslashish ham kerak. Hujayra o'sishini rag'batlantirish uchun sarum va boshqa moddalarni qo'shing. Shuning uchun media bottles hujayra madaniyati sohasida keng qo'llanilishiga ega.
Sarum plazmadan fibrinogenni olib tashlash natijasida hosil bo'lgan juda murakkab aralashma bo'lib, asosan homila sigir zardobi, buzoq zardobi, kattalar sigirini o'z ichiga oladi. zardob, ot zardobi, echki zardobi, tovuq zardobi, quyon zardobi va boshqalar, ular orasida homila sigir zardobi ishlatiladi. eng ko'p qo'llaniladi. Sarum hujayradan tashqari matritsa, o'sish omillari va transferrin kabi muhim moddalarni beradi. Qo'shilgan sarumning nisbati turli hujayralar va turli tadqiqot maqsadlariga ko'ra aniqlanishi kerak. 10% ~ 20% sarum hujayralarning tez o'sishi va ko'payish tezligini saqlab turishi mumkin, bu o'sish muhiti deb ataladi; Hujayralarning sekin o'sishi yoki o'lmasligini ta'minlash uchun 2% ~ 5% sarum qo'shilishi mumkin, bu parvarishlash vositasi deb ataladi.
Sarumning o'ziga xosligi tufayli uni saqlash harorati -5 ° C dan -20 ° gacha bo'lishi kerak. C. Media butilkalari odatda shaffof PET materialidan in'ektsiya cho'zilgan puflash texnologiyasi bilan ishlab chiqariladi. Ushbu material yaxshi issiqlik qarish qarshiligiga ega, -70 °C mo'rtlashuv haroratiga ega va hali ham -30 °C da ma'lum qattiqlikka ega, bu sarumni saqlash ehtiyojlarini qondiradi. . Va media shisha sterilizatsiya qilinadi, hech qanday pirojen, endotoksin, DNaz, RNaz va hujayra o'sishiga ta'sir qiluvchi boshqa omillar.
Sarum hujayra madaniyati uchun ajralmas element hisoblanadi. Biologik mahsulotlar, immunoterapiya, ilmiy tadqiqot institutlari va boshqa sohalarning uzluksiz rivojlanishi bilan sarumga bo'lgan talab ham ortadi va media shishasi hujayra madaniyati sohasida ham kengroq qo'llaniladi.
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.
