Protein A is a bacterial cell wall protein, originally derived from Staphylococcus aureus, that exhibits a high affinity for the Fc region of immunoglobulins （IgG）. It is widely used in various applications, such as antibody purification, immunoassays, protein-protein interaction studies, and therapeutic antibody development. Protein A residues can potentially be present in biopharmaceutical products as a result of the purification process using Protein A affinity chromatography. The presence of Protein A residues in the final product is a concern due to their potential immunogenicity and safety implications. Therefore, the detection and quantification of Protein A residues in biopharmaceutical products is crucial for ensuring product quality and patient safety. This simple, sensitive, and fast OneStep ELISA is a powerful method for optimizing purification processes, process control, routine quality control, and product release testing.
