laboratoriyada hujayra madaniyati va hujayra kengayishi uchun madaniyat idishidir. Hujayra o'sishi ma'lum bir muhit va haroratni talab qiladi. Shuning uchun hujayra madaniyati kolbalarini hujayra madaniyati uchun ishlatganda, siz noto'g'ri ishlashdan va hujayra o'sishiga ta'sir qiluvchi ifloslanishdan qochishingiz kerak.1. Tajribadan oldin qo'lingizni yuving: Ko'pgina tajribachilar qo'llarini o'zlari yuvmaydilar va spirtli ichimlik püskürtülmesi bilanoq tajribaga boradilar. Bu noto'g'ri xatti-harakatlar. Qo'lingizni sovun / sovun bilan ehtiyotkorlik bilan yuving, bilak va tirnoqlarni yuving. Qo'lingizni ikki marta yuvib, so'ng qo'lingizga spirt sepsangiz yaxshi tanlov.hujayra kulturasi
2. Kimdir tajriba o'tkazish uchun yarim yengli oq xalat kiyadi. Oq xalatning manjetlari uzun bo'lishi kerak, bu manjetlar mahkam bog'langan turdagi. Agar yo'q bo'lsa, manjetlarni qo'l tomonga qo'ying. Yalang'och bilaklar ham spirtli ichimliklar bilan püskürtülmelidir. Iltimos, qo'lqop kiyganingizdan keyin ish stolining tashqi tomoniga tegmang. Agar siz unga tegishingiz kerak bo'lsa, yana spirtli ichimliklarni püskürtün. To'g'rirog'i, qo'lqoplar spirtli ichimliklarni ko'proq hidlaydi.
3. Hujayra madaniyati kolbasi va madaniyat muhitini ushlab turganda, iltimos, uni ostidan ushlab turing va tiqilib qolgan qismini olmang.
4. Har kuni tajriba boshida ultra toza skameykada/tajriba xonasida 20 daqiqa ultrabinafsha nurni olish yaxshi tanlovdir.
5. Shuni ta'kidlash kerakki, o'ta toza stolning tarkibini iloji boricha kamroq saqlash kerak. Qanchalik ko'p qo'ysangiz, ifloslanish shunchalik oson bo'ladi.
6. Operatsiya paytida gaplashmaslikka harakat qiling, ayniqsa kamera xonasida hazil qilish qat'iyan man etiladi.
7. Har kuni hujayra holatini kuzatib boring. Hujayraning anormal o'sishini topsangiz, uni tashlab yuboring. Shu bilan birga, havodagi mikoplazma tufayli, kultura suyuqligi va inkubatoringiz ifloslanganligini tekshirib ko'ring.
Hujayra madaniyati juda jiddiy ishdir.
va boshqa sarf materiallaridan foydalanganda, hujayralar ifloslanish tufayli ularning o'sishiga ta'sir qilmasligi uchun turli xil ifloslanish manbalarini yaratishga alohida e'tibor bering.cell culture flasks hujayra 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.
