Perfusion model is normally chosen for the production of unstable proteins. This is because perfusion culture has low resident time

in bioreactor and the product can be harvested and purified promptly. In addition, it can avoid the accumulation of toxic or

inhibitory metabolites that might have negative impact on the productivity of fed-batch cultures. Perfusion cultivation is carried out

by continuously feeding fresh medium to the bioreactor and constantly removing the cell-free spent medium while retaining the

cells in the reactor; thus, a much higher cell density can be obtained in perfusion cultures compared to continuous cultures, as cells

are retained within the reactor via a cell retention device. The perfusion rate depends on the demand of the cell line, the

concentration of nutrients in the feed, and the level of toxification.

What is culture.?

culture defines who a person is, where they come from [in some cases], what they eat, what they wear, what they believe in.

There's the American culture, the English, the Irish, the Scottish, the French, the Spanish, the Chinese, the Indian, the Egyptian, the Argentine, etc.; the list just goes on and on. Regions, states, cities, etc. also have their own culture. For example there is the Californian culture, the Western European culture, the Parisian culture, the Pacific Island culture, etc. Any place you can think of most likely has its own culture.


How many years after the yangshao culture did the longshan culture develop?

The Longshan culture developed roughly 2,000 years after the Yangshao culture, around 3,000 - 2,000 BCE in the central plains of China. The Longshan culture is known for its advanced pottery techniques and social organization compared to the Yangshao culture.


Is culture individual?

Individual culture is a culture that values the individual over the group. This contrasts with a collectivist culture, which values the individual only with respect to their contribution to a certain social group.


What are the territories of culture?

The territories of culture are: local, national and global culture. Local culture are those practiced by a certain group of people in the community. National culture, on the other hand, transcends local culture. Example, in the Philippines, the common thing is their culture as Filipinos, no matter the variation of their local culture. Global culture is the dominant belief and norms practiced and accepted globally.

Why is perfusion important?

Perfusion is important because it ensures that tissues and organs receive adequate blood flow to meet their metabolic needs, delivering oxygen and nutrients while removing waste products. Proper perfusion is essential for tissue viability and overall physiological function. Impairments in perfusion can lead to tissue damage, organ dysfunction, and potentially life-threatening conditions.


What is wasted perfusion?

Wasted perfusion refers to blood flow that does not contribute effectively to tissue oxygenation or metabolism. This can occur in conditions such as shock, where blood flow is directed away from vital organs, leading to tissue hypoperfusion despite adequate total blood flow. Monitoring markers of tissue perfusion, such as lactate levels, can help assess the degree of wasted perfusion.
