し、本発明を完成した。However, conventional culture media require the addition of serum for cell growth, but serum contains extremely high levels of antibodies and cell growth inhibitors, and is used in various fields such as immunology. It is known that this causes unfavorable results in tower cultivation. Therefore, it has been desired to develop a culture solution that can grow cells without adding serum.
Many studies have been conducted, but nothing satisfactory has been provided yet. Therefore, in an attempt to solve this momme point, the present inventor conducted various studies on the cell proliferation effect of a culture solution containing a bovine serum albumin fraction (Cohn's serum fraction V) (hereinafter referred to as A) and a higher fatty acid. When polyethyleneimine was added to this layer, the cell proliferation effect was significantly increased.
The present invention was completed based on the discovery that the amount of BSA can be reduced to an extremely small amount.
