Zooblast culture medium dry powder composition, culture medium composition and preparation method thereof

Abstract

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 otherbiological products.

Description

Animal cell culture medium dry powder composition, culture medium composition and preparation method thereof technical field The invention relates to a dry cell culture medium composition, a cell culture medium composition and a preparation method thereof, in particular to an animal cell culture medium dry powder composition, an animal cell culture medium composition and a preparation method thereof. Background technique In the existing animal cell culture, the animal cell culture medium dry powder composition is generally dispersed in a carrier (such as redistilled water) to form a liquid medium composition, and then used in conjunction with animal serum at a final concentration of at least 10% by volume; or The animal cell liquid medium composition without animal serum is used in conjunction with the animal serum with a final concentration of at least 10% by volume; or directly using a liquid medium composition including animal serum with a final concentration of at least...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to overcome the disadvantages that the existing dry powder composition of animal cell culture medium must be used in conjunction with high-content animal serum to promote the growth of animal cells and have poor safety, and to provide a dry powder composition of animal cell culture medium. The concentration of animal serum can promote the growth of animal cells with good safety
