When culturing cells, we often use cell culture flasks, whose specifications range from 75cm2 to 225cm2, to meet the needs of cell culture of different scales. Depending on how the cells are cultured, this vessel has two different surfaces: TC-treated and non-TC-treated.
Cells are divided into adherent cells and suspension cells according to the different culture methods. The growth of adherent cells must have a support surface that can be attached, and cells can grow on this surface by relying on the attachment factors secreted by themselves or provided in the medium. , breeding. Suspension cells do not require an attachable support and grow in suspension in the medium, such as lymphocytes.

The cell culture flask is made of polystyrene raw material. This material itself is hydrophobic, which is not conducive to the better adherence of cells. Therefore, it needs to be treated with TC on the surface to change its performance, so that the cells can better adhere to the wall. grow. There is no such requirement for suspension cells, but generally TC-treated containers are also suitable for suspension culture of cells.

In short, cell culture flasks treated with TC on the surface are more suitable for adherent culture of cells, and containers without TC treatment are suitable for suspension culture of cells. When choosing a cell culture container, we must first determine the cell culture method, and then select a suitable container, so as to ensure the good growth of the cells and the smooth progress of the experiment.
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.
