When thawing serum, the serum should be placed in a refrigerator at 2-8 ° C, and shaken frequently to dissolve it, then placed at room temperature to warm it up. Never put the frozen serum directly into a 37 ° C water bath or incubator, such as Thaw at 37 ° C, the color is deepened, the viscosity will also increase. After thawing and heat inactivation, the serum should be stored according to the dosage and stored at -20 ° C to avoid repeated freezing and thawing.

Fetal bovine serum is the serum of fetal calf obtained by cardiac puncture at the time of slaughtering pregnant cows. The newborn calf (calf) serum is collected from calves born 10 to 14 days old. The composition is different from the ratio: the components of the growth-promoting factor, the adhesion-promoting factor, the hormone and other active substances are different from each other, and the use and usage are different: some cells must have fetal bovine serum to grow, and some The cells only need calf serum, and the concentration is different, generally 5%-10%, and the concentration is 20%.
