Cell culture is a fundamental technique in biological and medical research, and roller bottles have become increasingly important as a unique cell culture tool. Roller bottles provide ample growth space for cells. The rotation of the bottle by a roller apparatus allows cells to grow on a larger surface area, thus enhancing cell growth rate and yield.
This is particularly beneficial for experiments and research requiring large quantities of cells, such as drug screening and toxicological studies. The gentle rotation helps prevent sedimentation of certain components in the culture medium, ensuring a stable culture environment. Researchers can observe the growth status of cells at any time and adjust the culture conditions accordingly.
This real-time monitoring capability enables better control over the cell growth process, enhancing the accuracy and reliability of experiments.
Roller bottles are suitable for the culture of various adherent cells, such as:
Vero Cells
HEK 293 Cells
CAR-T Cells
MRC-5 Cells
Chicken Embryo Fibroblast (CEF) Cells
They are also suitable for the static culture of suspension cells such as:
CHO Cells (Chinese Hamster Ovary Cells)
Insect Cells
BHK21 Cells (Baby Hamster Kidney Cells)
MDCK Cells (Madin-Darby Canine Kidney Cells)
As technology continues to advance and application demands diversify, roller bottles will continue to play a crucial role, driving the ongoing development of biological and medical research.
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.
