Precise quantitation, high throughput automation, and broad chemical coverage are essential to accelerate development of next-generation biologics while ensuring product quality and safety.

Objectives and study overview

This guide consolidates Shimadzu’s integrated analytical technologies and workflows designed for various stages of biopharmaceutical research. It illustrates methods for:

• Cell line optimization and nucleic acid quantitation
• Culture monitoring of nutrients, metabolites, and trace elements
• Purification and high-resolution fraction analysis
• Structural characterization of proteins, glycans, and aggregates
• Quality control of elemental impurities
• Quantitative bioanalysis and pharmacokinetics

Methodology and instrumentation

A suite of spectroscopic and chromatographic techniques is deployed:

• UV-Vis microvolume quantitation (TrayCell, Nano Stick, UV-1900i)
• Microfluidic electrophoresis (MCE-202 MultiNA) for DNA/RNA analysis
• Automated colony picking (CELL PICKER) and cell phenotyping
• Atomic absorption (AA-7000) and ICP-MS (ICPMS-2030) for metal analysis
• UHPLC-MS/MS profiling (Nexera X3 with LCMS-8060) of amino acids, vitamins, and metabolites
• Automated pretreatment and LC-MS integration (C2MAP-2030)
• Inert LC fractionation and column switching (Prominence inert LC + LH-40)
• Protein sequencing by Edman degradation (PPSQ-51A/53A) and MALDI-TOF (MALDI-8020, MALDImini-1)
• Peptide mapping by high-repeatability UHPLC (LC-2060 series)
• Secondary structure analysis by FTIR (IRTracer-100)
• Fluorescence detection of glycans and proteins (RF-20Axs)
• Aggregate sizing by laser diffraction (Aggregates Sizer) and flow imaging (iSpect DIA-10)
• Differential scanning calorimetry (DSC-60 Plus) for thermal stability
• Antibody quantitation by nSMOL and micro-flow LC-MS (LCMS-8050/8060, Nexera Mikros)
• Comprehensive metabolomics (GCMS-TQ8040 NX, LCMS-8040/8050)
• Volatile gas biomarker profiling (HS-20 + GCMS-QP2020 NX or SCD-2030)

Main results and discussion

Microvolume UV-Vis devices achieved reliable nucleic acid and protein assays with high linearity at microliter scale. Automated electrophoresis and colony picking increased throughput and reproducibility. Flame and graphite furnace AAS, as well as ICP-MS, enabled trace metal monitoring in cell culture media. Ultrafast UHPLC-MS/MS methods profiled up to 125 culture metabolites in 20 minutes. Integrated pretreatment (C2MAP) streamlined sample cleanup to LC-MS analysis. Inert LC systems combined purification and analytical workflows. Edman/MALDI sequencing yielded accurate primary structure data, while FTIR resolved secondary structure changes on heating. Glycan profiles were detected with fluorescence-labeled HPLC and MALDI MSn for sialyl linkage discrimination. Aggregate size and concentration were quantified dynamically under stress conditions, and subvisible particles were imaged in μL samples. DSC characterized protein stability in dilute solutions. LC/MS platforms and nSMOL enabled robust quantitation of therapeutic antibodies down to low ng/mL levels in plasma. GC/MS and LC/MS metabolomics revealed hundreds of small-molecule biomarkers, and volatile profiling of intestinal flora distinguished in vivo phenotypes. MALDI profiling differentiated disease and drug-resistant cell lines.

Benefits and practical applications

• Minimized sample volumes (sub-μL to μL) and micro-flow regimes conserve precious materials
• High-speed data acquisition (scan speeds up to 29 000 nm/min or 30 000 u/s) accelerates throughput
• Automated pretreatment and integrated systems reduce manual steps and improve consistency
• Low-adsorption consumables ensure accurate long-term storage and low carryover
• Broad analyte coverage from ions to large proteins and complexes supports multi-omics
• Regulatory compliance through validated methods for ICH Q3D, PK bioanalysis, and quality auditing

Future trends and potential applications

• Further integration of robotics and microfluidics for end-to-end automated workflows
• Single-cell and organ-on-a-chip analytics to drive precision medicine
• Artificial intelligence–driven data analysis for predictive bioprocess control
• Expanded multi-omics platforms combining proteomics, glycomics, lipidomics, and metabolomics
• Remote operation and digital twin models for accelerated biomanufacturing
