Workflow

From target to bioprocess

Whether you're advancing a novel biologic, developing a peptide therapeutic, or scaling a biosimilar, our portfolio across several partners from around the world supports every stage of drug development — from target identification through GMP manufacturing.

Represented Brands

Identify & Validate Target

Validated antibodies, antigens, proteins and peptides across disease areas and applications — starting reagents for target identification.

Screen & Characterize Candidates

Cytokine and biomarker ELISA kits, enzymatic and compendial assays for early candidate screening and target validation.

Characterize Lead Candidate

Physicochemical characterization — aggregation, charge variant, and glycosylation profiling for expressed biologics; purity and sequence confirmation (HPLC, mass spec-compatible reagents) for synthesized peptides.

Assess PK & Immunogenicity

Pharmacokinetic and anti-drug antibody (ADA) ELISA kits supporting preclinical and clinical-stage development, across biologics and peptide programs.

Develop Upstream Process (Biologics)

Cell line development, media and feed optimization reagents for expressed biologics. Not applicable to synthesized peptides — see Peptide Synthesis & Purification instead.

Synthesize & Purify Peptide

Solid-phase synthesis reagents and HPLC-based purification for peptide therapeutics. Applies in place of upstream/downstream cell-culture steps.

Develop Downstream Process & Purification (Biologics)

Chromatography resins and purification reagents, plus process-related impurity clearance testing (HCP, HCDNA, residual Protein A/Benzonase) for cell-culture-derived biologics as the batch moves downstream.

Scale to GMP Manufacturing

Bioprocess equipment, consumables and GMP-grade raw materials for production-scale manufacturing.
