Sarum hujayra o'sishi va hujayra madaniyatida ko'payishida almashtirib bo'lmaydigan rolga ega, shuning uchun zardob hujayra madaniyatida qanday rol o'ynaydi va media bottle qadoqlash uchun qanday talablar mavjud?
Sarum funktsiyasi:
1. Sarumning asosiy moddalari oqsil, albumin va boshqalar bo'lib, ular hujayra madaniyati muhitining pH qiymatini buferlashi va osmotik bosimni ushlab turishi mumkin;
2. Transferrin va tiroksinni bog'lovchi oqsil kabi bog'lovchi oqsillar vitaminlar, lipidlar, metallar va boshqa gormonlar va boshqalarni taniy oladi va zaharli metallar va pirogenlar bilan birikishi mumkin;
3. Xomilaning sigir zardobidagi fibronektin, homila va adezyon omillari hujayra yopishishi va tarqalishiga yordam beradi;
4. Trombotsitlar o'sish omili, fibroblast o'sish omili, epidermal o'sish omili, asab hujayralari o'sish omili, insulin, insulinga o'xshash o'sish omili, somatotropin, gidrokortizon va boshqalar kabi polipeptidlar hujayra bo'linishi va ko'payishini qo'llab-quvvatlaydi va hujayralar logarifmik o'sishini saqlab turishi mumkin;
5 . Makroglobulin kabi proteaz inhibitörleri proteazni inhibe qilishi va hujayralarni shikastlanishdan himoya qilishi mumkin;
6. Sarum shuningdek, aminokislotalar, glyukoza, keto kislotalar va oqsillar bilan birlashtirilgan mikroelementlarga boy bo'lib, ularning barchasi hujayra madaniyati uchun muhim ahamiyatga ega.
Ommaviy axborot vositalariga qo'yiladigan talablar:
Sarum murakkab tarkibiy qismlarga va muhim funktsiyalarga ega, shuning uchun saqlash va ulardan foydalanish sarum juda muhimdir. Sarum idishlarini tanlashda shisha tanasi odatda shaffof bo'lishi, DNase, RNase, pirogen va hujayra o'sishiga ta'sir qiluvchi boshqa moddalardan xoli bo'lishi va oqishning oldini olish uchun muhrlangan bo'lishi kerak. Shunisi e'tiborga loyiqki, sarum odatda -5 °C dan -20 °C gacha bo'lgan muhitda saqlanishi kerak, shuning uchun media shishasining materiali ham past haroratga chidamlilik xususiyatlariga javob berishi 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.
