The present invention discloses a complete medium for culturing DF-1 cells, including DMEM basal medium 13.7g / L, insulin, non-essential amino acids, transferrin, glutathione, ascorbyl phosphate, sodium selenite, ethanolamine, hydrocortisone, and newborn calf serum. Wherein non-essential amino acids include glycine, alanine, proline, serine, and asparagine. A complete medium for culturing DF-1 cells provided by the present invention can well promote the proliferation of DF-1 cells, can achieve the same proliferation effect as high-concentration fetal bovine serum, and is suitable for the adherent culture of DF-1 cells; using low-concentration newborn calf serum, it is possible to greatly avoid the batch differences, unstable culture results, cytotoxicity, and high risk of carrying pathogens brought by the culture medium with high-concentration serum, narrow application range, expensive fetal bovine serum, and high culture cost; the components are simple, the culture medium preparation process is short in time consumption, the culture efficiency is high, the repeatability is good, and it is suitable for batch production.

In the formula, M is a hydrogen atom or a monovalent metal ion.

This invention discloses a method for the bioenzymatic synthesis of ascorbate phosphate succinyl tripeptide-1, belonging to the field of bioengineering technology. This method involves constructing a fusion protein expression system through genetic engineering, releasing the target tripeptide GHK (glycylhistyllysine) through specific enzymatic cleavage, and then conjugating it to the succinyl group of ascorbate phosphate via an enzymatic catalytic esterification reaction, ultimately obtaining high-purity ascorbate phosphate succinyl tripeptide-1. Compared with traditional chemical synthesis methods, this method has advantages such as shorter synthesis steps, milder conditions, environmental friendliness, and high yield (>85%), making it suitable for large-scale industrial production and showing broad application prospects in the cosmetics and pharmaceutical fields.
