Is there known correlation between media composition and glycosylation of proteins?

Answer

There are medium components known for impacting protein glycosylation through different mechanisms. For example, manganese serves as a cofactor in the glycosylation pathway and can improve glycosylation; galactose impacts glycan precursors and may improve glycosylation; high glutamine in medium formulation can cause less glycosylation due to ammonia generation.
