We handle all essential in-process and release testing, from bulk harvest to drug substance (DS) and drug product (DP) release, ensuring that your biologic product consistently meets these critical quality standards. Our platform methods ensure that your biologic’s early-phase development is efficient, regulatory-compliant, and ready for rapid clinical progression.
Our Platform Services include a broad range of standardized assays and characterization techniques, such as:
In-Process Testing
- Monitoring key attributes like titer (in g/L), Spent media analysis, glycan variants, charge heterogeneity & size heterogeneity to ensure the desired product quality during the process optimization.
Release Testing (Drug Substance and Drug Product)
- Quantification: IgG titer estimation, protein concentration by Fixed path length (UV spectrophotometry)/ by Variable path length (Stunner).
- Purity & Impurity Profiling: Identification of high-molecular weight aggregates, low-molecular weight fragments, and process-related impurities like host cell proteins (HCP) and Host cell DNA (HcDNA) through techniques like Size Exclusion Chromatography (SEC), CE-SDS, RT-PCR and ELISA.
- Identity Testing: Confirming the primary amino acid of the product by peptide mapping (RP-LC) and determination of Isoelectric point (PI) by cIEF.
- Glycan Profile: Identification and monitoring the N-Linked Glycan variants by HILIC at various stages like; In-process & DS Release and Quantification of Sialic acid (NANA & NGNA) by RP-LC (FLR) during the process optimization
- Charge Heterogeneity: Analysis of charge variants to ensure product consistency using Ion Exchange Chromatography (IEX).
- Safety Testing: Ensuring product safety by performing sterility, endotoxin, and bioburden testing.
