Cultivating cells is like raising children. Care must be taken to care for them. A little carelessness may affect the growth of cells. Precipitation of the culture medium in the cell culture flask is a common problem. What is the reason for this and how can we deal with it?

In fact, there are two main reasons for the precipitation of the solution in the cell culture flask. On the one hand, the cells themselves are contaminated, and on the other hand, the culture medium contains metals, proteins and other medium components. From the perspective of cell contamination, common cell contaminations include bacterial and fungal contamination, mycoplasma contamination, eukaryotic cell contamination, etc. After contamination, the culture solution will turn yellow and precipitate. At this time, it is recommended to treat the culture immediately. Re-establish the culture.

Another reason is the composition of the medium itself. If after investigation, it is determined that there is no contamination, it is likely to be the precipitation of metals, proteins and other media components in the cell culture medium. These precipitates may affect the health of the cells, because they generally remove nutrients and other nutrients through chelation. required components, thereby changing the composition of the medium. Changes in temperature, concentration changes induced by water loss, calcium salts, metal supplements, etc., are all likely to cause precipitation of the medium.

In short, if there is precipitation in the cell culture flask, there may be many reasons. We must investigate carefully and find out the specific reasons to solve the problem.

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.
