Within our integrated Pharmaceutical Development & Manufacturing framework, we specialize in Drug Substance Development for complex plasma-protein analogs, with a dedicated practice in Blood Factor Development. We deliver phase-appropriate, science-driven programs for recombinant coagulation blood factors, emphasizing robust processes, deep analytical characterization, and manufacturability-ready documentation.
Overview of Recombinant Coagulation Blood Factor Development

Recombinant coagulation factors present unique development challenges due to multidomain architecture, extensive post-translational modifications, and sensitivity to processing conditions. Vitamin K–dependent factors require precise γ-carboxylation for calcium binding; others, such as factor VIII, depend on correct glycosylation, disulfide pairing, and cofactor interactions that influence stability and activity. Expression system selection (commonly CHO or HEK), media composition, vitamin K recycling, and co-expression of processing enzymes strongly affect product quality attributes. Downstream, gentle but selective purification is essential to preserve conformational integrity while achieving low host-cell impurity levels. Potency determination relies on orthogonal assays—chromogenic activity tests, thrombin-generation profiling, and structure-focused analytics (intact mass, glycan mapping).
Our Services
We provide an integrated, development-focused service portfolio tailored to recombinant coagulation factors. The offering spans expression system engineering, upstream control of post-translational modifications, comprehensive analytical method development, stability studies, and CMC-ready documentation.
Expression System & Cell Line Engineering Service
We design and generate high-performing CHO or HEK cell lines suitable for secreting complex coagulation factors, incorporating codon optimization, signal peptides, and selection strategies that favor product quality. When applicable, we co-express processing enzymes (e.g., furin) or accessory proteins to enhance maturation and secretion. Clonal screening includes high-throughput activity readouts and early quality fingerprints to ensure the line supports downstream specifications.
Upstream Process Development Service
We build chemically defined, scalable upstream processes tuned for quality attributes: feed strategy, dissolved gases, and shear management. For vitamin K–dependent factors, we configure vitamin K supplementation and recycling conditions that support efficient γ-carboxylation. We apply DoE-driven optimization to balance titer, specific activity, and critical quality attributes (CQAs), establishing scale-down models that predict performance at larger volumes.
Post-Translational Modification Control Service
We implement targeted controls for γ-carboxylation, glycosylation, sulfation, and proteolytic processing. Analytical feedback loops (e.g., Gla content profiling, glycan mapping) guide media additives, pH/CO2 strategies, and process intensification choices. For factor VIII programs, we address vWF-related stability considerations using tailored upstream tactics and downstream conditioning to maintain activity.
Analytical Method Development & Qualification Service
We establish a phase-appropriate, fit-for-purpose analytical toolbox: identity and purity (RP/SEC/HIC), host-cell impurities, residual DNA, intact/fragment mass, glycan and PTM profiling, and bioactivity (chromogenic and amidolytic assays, thrombin-generation kinetics). Method lifecycle management includes qualification, system suitability, and reference standard handling aligned to evolving specifications.
Stability & Forced-Degradation Study Service
We design accelerated, stress, and long-term stability protocols to reveal degradation pathways—oxidation, deamidation, fragmentation, and aggregation. Outputs inform formulation selection, primary-container compatibility, and allowable shipping conditions. We use orthogonal analytics to ensure degradants are well characterized and controlled.
CMC-Ready Documentation & Data Package Service
We compile development reports, risk assessments, control strategies, and method documentation suitable for inclusion in pharmaceutical development dossiers. Content is structured to articulate the process, CQAs, and supporting data.
