{"id":74,"count":6,"description":"Arginine is a naturally occurring amino acid that is commonly used as an excipient in biologics manufacturing to improve the stability and manufacturability of therapeutic proteins such as monoclonal antibodies. In formulation, arginine can help reduce protein\u2013protein interactions that contribute to aggregation, precipitation, and high solution viscosity\u2014issues that often become more pronounced in high-concentration biologic drug products. By supporting better solubility and solution behavior, arginine can make downstream processing steps like mixing, filtration, and fill\/finish more efficient and consistent, while also helping maintain product quality throughout storage and handling.","link":"https:\/\/pfanstiehl.com\/en\/high-purity-ingredients\/arginine\/","name":"L-Arginine","slug":"arginine","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
