Cell line development creates the cell system that expresses your antibody. A strong cell line improves stability, yield, and quality. Our upstream tools support high‑titer cell culture and consistent performance as you can scale up.

Most traditional mAb workflows begin with a Protein A capture step. This is followed by polishing steps, commonly using ion exchange chromatography or multimodal or hydrophobic interaction chromatography for challenging separation and to refine purity. In research applications, the capture step is commonly followed by a SEC step.

Your molecule’s behavior and impurity profile will guide the resin choices, and novel protein therapeutics such as ADCs, bispecifics, or fragments will have unique structural elements that might call for a different approach. We offer diverse resins and columns that help simplify protein separation decisions at every scale for any antibody molecule.

Viral clearance uses low‑pH inactivation, filtration, and orthogonal steps to protect product quality and patients. These steps sit after capture and before final formulation. It strengthens the reliability of your downstream sequence.

Our filtration and ultrafiltration and diafiltration (UF/DF) solutions help you meet safety targets without compromising efficiency.

You’re ready for scale‑up when upstream growth, critical quality attributes (CQAs), and recovery remain stable across runs. Predictable behavior in both upstream and downstream bioprocessing is a strong indicator. We help teams assess readiness and build scalable workflows that reduce operational risk.

Bioprocess modelling helps predict how cell line development, chromatography, or protein purification changes will affect yield and robustness. This capability reduces trial‑and‑error and surfaces risks earlier. We provide scalable systems and data that integrate cleanly into bioprocessing models.

Harvest clarification removes cells and debris before purification. Depth filtration works well with dense feeds. Centrifugation or tangential flow filtration (TFF) suit other formats. We can help you choose a protein purification method that protects your throughput and downstream consistency.

A mAb workflow begins with cell line development and moves to upstream expansion, harvest clarification, protein purification, and final formulation. Each stage shapes yield, quality, and cost. We help you link these steps with scalable bioprocessing tools that keep your workflow predictable.

A GMP‑ready process delivers consistent batches and stable CQAs. Defined operating limits and repeatable purification behavior support this stability. We help map gaps and strengthen your workflow, so you’re prepared for regulatory and operational scrutiny.
