I-flask Culture cell iwumkhumbi wamasiko wokwenza amaseli nokunwetshwa kwamaseli elabhorethri. Ukukhula kweseli kudinga indawo ethile kanye nezinga lokushisa. Ngakho-ke, lapho usebenzisa ama-flask e-cellculture yesiko lamaseli, kufanele ugweme ukusebenza okungalungile kanye nokungcola okuthinta ukukhula kwamaseli.
1. Geza izandla ngaphambi kokuhlolwa: Abaningi abahlolayo abazigezi izandla zabo ngokwabo, futhi baya esivivinyweni ngokushesha nje lapho utshwala sebufuthwe. Lokhu ukuziphatha okungalungile. Kufanele ugeze izandla zakho ngokucophelela ngensipho/insipho, futhi ugeze izihlakala nezinzipho zakho. Kuyisinqumo esihle ukugeza izandla kabili, bese ufutha utshwala ezandleni zakho.
2. Umuntu ugqoke ijazi elimhlophe elinemikhono enguhhafu ukuze enze izivivinyo. Ama-cuffs wejazi elimhlophe kufanele abe made, okuwuhlobo olunama-cuffs aboshwe ngokuqinile. Uma kungenjalo, beka izingodo ezingalweni. Izihlakala ezingenalutho kumele zifuthwe ngotshwala. Sicela ugweme ukuthinta ingaphandle lebhentshi lomsebenzi ngemva kokugqoka amagilavu. Uma kufanele uyithinte, fafaza utshwala futhi. Kunalokho, amagilavu anuka utshwala obengeziwe.
3. Uma uphethe i-cell culture flask kanye ne-culture medium, sicela uyibambe ngaphansi, futhi ungathathi ingxenye yebhodlela.
4. Ekuqaleni kokuhlolwa nsuku zonke, kuyisinqumo esihle ukuthatha imizuzu engu-20 yokukhanya kwe-ultraviolet ebhentshini/igumbi lokuhlola elihlanzeke kakhulu.
5. Into eyodwa okufanele uyiqaphele ukuthi okuqukethwe kwetafula elihlanzekile kakhulu kufanele kugcinwe kuncane ngangokunokwenzeka. Uma ubeka kakhulu, kuba lula ukungcolisa.
6. Zama ukugwema ukukhuluma ngesikhathi sokuhlinzwa, ikakhulukazi i-cell room inqatshelwe ngokuphelele ukwenza amahlaya.
7. Bheka isimo seseli nsuku zonke. Uma uthola ukukhula kwamaseli okungavamile, sicela ukulahle. Ngesikhathi esifanayo, ngenxa ye-mycoplasma esemoyeni, sicela uhlole ukuthi uketshezi lwesikompilo lakho kanye ne-incubator kungcolile yini. Uma usebenzisa
nezinye izinto ezisetshenziswayo, qaphela ngokukhethekile ukukhiqizwa kwemithombo ehlukahlukene yokungcola ukuze uvimbele amaseli ukuthi angathikamezi ukukhula kwawo ngenxa yokungcola.cell culture flasksamaflask amasiko amaseli
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.
