During biopharmaceutical manufacturing, residual process-related impurities, such as host cell proteins (HCPs) and media-derived additives, can adversely affect product safety, efficacy, and stability, making them critical quality attributes for quality control and regulatory release. Conventional detection approaches often face challenges, including insufficient specificity, limited sensitivity, and labor-intensive workflows. MtoZ Biolabs offers a comprehensive portfolio of impurity testing solutions covering key process-related impurities, combining high-sensitivity assay kits with validated analytical methodologies. These solutions support compliance requirements across all stages, from process development to final product release, helping ensure consistent drug quality and patient safety.
Products
1. BSA/HSA Residual Testing
MtoZ Biolabs provides high-sensitivity, high-specificity residual testing kits for Bovine Serum Albumin (BSA) and Human Serum Albumin (HSA). These assays are designed to monitor potential animal- or human-derived protein residues introduced during cell culture media preparation or downstream purification processes, supporting robust control of process-related impurities throughout biomanufacturing.
2. Non-Specific Nuclease Residual Testing
For nuclease-related impurities that may be introduced during production, MtoZ Biolabs offers sensitive and specific detection solutions to verify the absence of residual nuclease activity in final drug products. This ensures product stability and safety by eliminating risks associated with unintended nucleic acid degradation.
3. Kanamycin Residual Testing
For cell culture processes employing kanamycin-resistance systems, MtoZ Biolabs provides high-sensitivity kanamycin residual testing kits that support quantitative analysis in accordance with pharmacopeial requirements. These assays enable reliable monitoring of antibiotic residues to meet regulatory expectations.
4. Trypsin Residual Testing
To address enzyme residues such as trypsin used during cell dissociation or separation, MtoZ Biolabs offers specific and validated detection methods to monitor residual levels. These solutions are particularly important for ensuring the safety and quality of sensitive products, including cell therapy and advanced biologics.
