USPNF810G_GC 1132_2017-01 - US Pharmacopeia (USP) Residual HCPs have the potential to affect product quality, safety, and efficacy; therefore, the quantity of HCPs should be low The product purification processes must be optimized to consistently remove as many HCPs as feasible, with the goal of making the product as pure as possible
#288 - U. S. Food and Drug Administration Different host cell lines, including mammalian, yeast, bacteria, plant, or insect, and cell-free systems can be used for expressing recombinant proteins The choice of host cells may be
General Chapter Residual Host Cell Protein Measurement in . . . USP general chapter <1132 1> Residual Host Cell Protein Measurement in Biopharmaceuticals by Liquid Chromatography-Mass Spectrometry was published in Pharmacopeial Forum 49 (3) and subsequently approved for publication on November 1, 2024, in USP-NF 2025, Issue 1
USP 1132. 1 : How to perform HCP analysis by MS - Alphalyse It provides best practices for measuring residual host cell proteins (HCPs) in biologics using liquid chromatography–mass spectrometry (LC-MS MS) The chapter supports regulatory compliance by offering detailed guidance on method validation, system suitability, and quantitation of individual HCPs
Residual host cell proteins: sources, properties, detection methods and . . . Host cell proteins (HCPs) are process-related impurities derived from host organisms used for recombinant protein production in biopharmaceutical manufacturing The generation of HCPs may lead to potential safety risks, such as immunogenicity, reduced drug e cacy and long-term side e ects
USP lt;1132 gt; Residual Host Cell Protein Measurement in Biopharmaceuticals USP <1132 1>, effective May 1, 2025, extends this framework with detailed guidance for MS-based HCP analysis Scope: Guidance on assay development, optimization, validation qualification, orthogonal characterization, and lifecycle monitoring of residual HCPs across development and commercial stages
Proteins Peptides Residual Host Cell Protein (HCP) Analysis Residual host cell protein (HCP) is a major class of process-related impurities that regulatory agencies require manufacturers to demonstrate have been eliminated during the development of protein peptide biologics to ensure drug purity, manufacturing process consistency, and patient safety
