PK-15 Low Serum Medium supports PK-15 cell stationary cultures and low serum suspension cultures in microcarrier bioreactors.

With PK-15 cell low serum medium, the cell passaging and seeding ratio can reach 1:4~1:7, and the cell growth status is good. Compared with the traditional catalog medium, PK-15 Cell Low Serum Medium can increase the cell passaging and seeding ratio, reduce the cell culture time, and improve the viability of PK-15 cells. It is suitable for PK-15 cell banking, seed cell resuscitation and cell production. The use of PK-15 low serum medium microcarrier reactor suspension culture PK-15 cells, can effectively reduce the serum components and serum potential exogenous viruses in the product quality hazards, improve product quality; the use of the reactor microcarrier culture can improve the production efficiency of the product, increase the virus yield, thereby reducing production costs. Currently, there are two types of circovirus vaccines: whole virus inactivated vaccine and subunit vaccine.PK-15 cells are the most suitable host for circovirus. The amount of serum in the virus maintenance fluid is positively correlated with the probability of developing immune stress.
