Application

Histidine is used in biopharma manufacturing as a buffer in formulation. It is often used together with histidine monohydrochloride to prepare histidine buffer with the desired pH value.
Due to its low microbial and endotoxin limits, L-Histidine Emprove® Expert is especially suitable for high-risk applications.

Biochem/physiol Actions

Precursor of histamine by action of histidine decarboxylase.
