Protein Sciences
Protein sciences investigate the structure, function, and interactions of proteins in biological systems. Workflows typically involve protein expression, purification, identification, and quantification. These steps are essential for characterizing proteins and understanding their roles in cellular processes such as signalling pathways and disease mechanisms.
Recombinant protein production plays a central role in this field and is critical for the development of biotherapeutics, including monoclonal antibodies and protein-based vaccines.
How Hamilton Supports Protein Science Workflows
Protein sciences often require the screening of numerous conditions to optimize protein expression, purification, and characterization.
Hamilton provides researchers with flexible, high-throughput solutions that streamline protein workflows. These include automated Society for Biomolecular Screening (SBS) format screening and small-scale fermentation systems for protein production. Our liquid handling platforms can be equipped with in-tip chromatography technology, centrifuges, Solid Phase Extraction (SPE), and filtration modules to streamline protein automation through automation-friendly purification and sample preparation steps.
We provide standardized and customized automated solutions to support a wide range of analytical methods, including ligand binding assays such as Enzyme-Linked Immunosorbent Assay (ELISA) and Liquid Chromatography-Mass Spectrometry (LC-MS) based quantification, helping you generate consistent and reliable results.
For labs working manually, our portfolio also includes high-precision manual pipettes for accurate and ergonomic liquid handling.

Overview of Common Techniques Used in Protein Science Applications
Protein Expression
Proteins are expressed in a variety of systems. Glycosylation, size and toxicity are just some of the characteristics that contribute to the choice of the right expression system. Due to its simplicity, expression in E. coli is still widely used. However, expression in eukaryotic systems or cell-free protein synthesis is becoming increasingly important.
Protein Purification and Concentration
In order to analyze produced proteins, effective purification and concentration are essential. The choice of method depends on factors such as protein concentration, post-translational modifications, and biological activity, particularly when meeting regulatory standards set by the Food and Drug Administration (FDA) and similar authorities. Common workflows combine multiple steps tailored to the target protein’s properties, and many labs now rely on an automated protein purification process to increase throughput and consistency.
Core purification techniques include:
- Chromatography (e.g., affinity, ion exchange, size exclusion) for high-resolution separation
- Precipitation for initial enrichment or bulk separation
- Filtration and Ultrafiltration for clarification, concentration, or buffer exchange
- Solid Phase Extraction (SPE) in specific analytical workflows, particularly for peptides or small proteins
Protein Characterization
To characterize proteins after production and purification, various analytical assays are used depending on the specific property being measured.
Core purification techniques include:
- Ligand-binding assays (e.g., ELISA, Fluorescence Resonance Energy Transfer (FRET))
- Activity assays (e.g., kinase activity, protease assays)
- Mass spectrometry (e.g,. Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS), Matrix-Assisted Laser Desorption/Ionization – Time of Flight Mass Spectrometry (MALDI-TOF MS)
- Surface plasmon resonance
- Isothermal titration calorimetry
