Hujayra madaniyati hujayra klonlash texnologiyasi deb ham ataladi, bu uning yashashi, o'sishi, ko'payishi va asosiy tuzilishini saqlab turishi uchun in vitroda ichki muhitni (steril, mos harorat, pH va ma'lum oziqlanish sharoitlari va boshqalar) taqlid qiladigan usulni anglatadi. va funksiya. Hujayra o'sishi uchun zarur bo'lgan sharoitlarga erishish uchun hujayra sarf materiallari kerak. Hujayra kulturalari ko'p qo'llaniladigan tur.
Hujayra kulturalari boy turlarga va ixtiyoriy qopqoqlarga xos xususiyatlarga ega. Turli shakllarga ko'ra, u kvadrat shishalarga, aylanadigan shishalarga, uchburchaklarga, tortikollislarga va boshqalarga bo'linishi mumkin. Har bir shisha o'ziga xos xususiyatlarga ega va turli hujayra madaniyati ehtiyojlariga mos keladi. Mahsulotlar uchun hujayra yopishish talablari nuqtai nazaridan u uch turga bo'linadi: oddiy turdagi, standart turdagi va maxsus turdagi. Masalan, maxsus turdagi sirtda azot o'z ichiga olgan funktsional guruhlar mavjud bo'lib, ular ma'lum maxsus hujayralarning (masalan, o'simta hujayralari) yopishishi va o'sishiga yordam beradi. Va farqlash. Shuni ta'kidlash kerakki, yopishgan hujayralar madaniyati hujayralarning yopishgan o'sishiga moslashish uchun kultura kolbasida TC sirtini ishlov berishni talab qiladi.
hujayra madaniyati kolbalari qopqoqlari muhrlangan qopqoq va filtr qopqoqlariga bo'linadi. Sızdırmazlık qopqoqlari ko'pincha havo o'tkazmaydigan madaniyat uchun ishlatiladi va shisha qopqog'i ochilganda ochiq kulturalar. Filtr qopqog'i ochiq madaniyat uchun javob beradi. Gaz almashinuvi jarayonida yuzaga kelishi mumkin bo'lgan o'zaro infektsiyani oldini olish uchun 0,2 um hidrofobik filtrli membrana qopqoqqa o'rnatiladi. Bu odatda karbonat angidrid inkubator madaniyati uchun tavsiya etiladi, ayniqsa uzoq muddatli kulturani talab qiladigan tajribalar uchun.
Hujayra kulturalarining bu xarakteristikalari hozirgi hujayra madaniyati ishining ehtiyojlariga asoslanadi. Ushbu talab nuqtalari texnologik taraqqiyotga qarab o'zgarishni davom ettiradi va hujayra madaniyati kolbalari ham shu asosda yangilanadi va takrorlanadi.
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.
