US 12,735,451 B2 · Peptide, cell growth promoter, protein production promoter, culture medium, cell growth method using peptide, and protein production method using peptide

Abstract

An object is to provide a synthetic culture medium not containing animal-derived components. In particular, an object is to provide a culture medium not containing animal-derived components but containing peptides that promote cell growth or contribute to promotion of protein production. A culture medium containing a peptide selected from the group consisting of Gly-Glu-Lys (GEK), Asp-Gly-Pro (DGP), Ala-Gly-Lys (AGK), Gly-Pro-Pro (GPP), Gly-Gly-Pro (GGP), Ala-Glu-Lys (AEK), Ala-Gly-Gly (AGG), Ala-Ser-Asn (ASN), and Glu-Gly-Lys (EGK) is provided.

A cell growth method, comprising:

acclimating animal cells to serum-free flotation using a basal medium,
adding one of peptides selected from the group consisting of Gly-Glu-Lys (GEK), Asp-Gly-Pro (DGP), Ala-Gly-Lys (AGK), Gly-Pro-Pro (GPP), Gly-Gly-Pro (GGP), Ala-Glu-Lys (AEK), Ala-Gly-Gly (AGG), Ala-Ser-Asn (ASN), and Glu-Gly-Lys (EGK), to the basal medium, and
seeding the animal cells acclimated to the basal medium in the basal medium to which the peptides have been added to perform cell growth.
