POWDER CELL CULTURE PRODUCT CONTAINING LIPID AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide powder nutritive culture medium, culture medium supplements, culture medium subgroup formulations.SOLUTION: The present invention provides cell culture medium supplements (including powdered sera such as powdered fetal bovine serum (FBS)), culture medium subgroup formulations, and cell culture media comprising all of the necessary nutritive factors including a lipid component that facilitates the in vitro cultivation of cells. The dry powder nutritive culture medium, the culture medium supplements, the culture medium subgroup, and buffer formulations are used for cultivation of prokaryotic and eukaryotic cells, particularly bacterial cells, yeast cells, plant cells, and animal cells (including human cells). Prior to this, aseptic powder culture medium, the culture medium supplements (particularly powdered sera such as powdered FBS, powdered transferrin, powdered insulin, powdered organ extracts (bovine brain or bovine pituitary extracts, etc.), powdered growth factor (EGF, FGF, etc.), etc.) the culture medium subgroup, and the buffer formulations are produced, antisepsis is achieved with γ-irradiation, and the culture medium, supplements, culture media subgroups, and buffer formulations are powdered.
