The invention provides a dry powder composition for a zooblast culture medium. Compared with the prior dry powder composition for the zooblast culture medium, the dry powder composition provided by the invention reduces the serum dosage of animals by introduction of recombinant protein or animal origin compositions, the dry powder composition for the zooblast culture medium can be matched with low-content animal serum for use without additional introduction of protein compositions (such as the recombinant protein, plant protein or the animal origin compositions including cytokines and so on), and has the same or better function on promoting the growth of zooblast compared with high-content animal serum, so that the dry powder composition for the zooblast culture medium does not generate side effects along with the protein compositions, and has good safety and low cost. Cells cultured by the dry powder composition for the zooblast culture medium have small difference for different batches, low cost and good safety, are favorable for separating downstream products of the cells, and are suitable to be used for virus hosts, expression vectors and so on of biological products and other biological products. |
