Delivering on the Promise of Purity

L-Histidine & L-Histidine monohydrate

Histidine has been shown to protect a monoclonal antibody in both the liquid and lyophilized state against heat stress and is becoming increasingly common in formulations of protein therapeutics.

Histidine is commonly used in biotherapeutic formulations as well as bioprocessing.

Histidine is the only amino acid with pH 7.4 within its buffering range, which means histidine is the best amino acid buffer under physiological conditions.

Pfanstiehl Brand High Purity / Low Endotoxin-Low Metal Histidine establishes a new quality standard for amino acids, designed specifically for Biopharmaceutical formulation and bioprocessing. Pfanstiehl Brand Histidine is available as USP (United States Pharmacopoeia), EP (European Pharmacopoeia), JP (Japanese Pharmacopoeia) and ChP (Chinese Pharmacopoeia).
