A method of producing erythropoietin having the enhanced sialic acid content using a lower molecular weight fraction of soy hydrolysates and erythropoietin having the enhanced sialic acid content produced by the same

摘要

The present invention relates to a method of producing a serum-free and protein-free cell, erythropoietin is the sialic acid content increased, comprising the step of culturing animal cells producing erythropoietin in the medium for culturing, including seafood conga water fraction to less than 5kDa and the sialic acid content is thus produced by provides an increased erythropoietin. ; Sialic acid, conga water seafood, low molecular weight fraction
