Proteins are core materials for life science research, assay development, and bioprocess workflows. Different protein classes, structural features, and application formats require different expression hosts, purification paths, and analytical controls. A practical service platform therefore needs both technical breadth and a consistent project workflow.

Nebulabio Protein Production Platform provides an integrated service framework covering expression system selection, recombinant protein production, purification, labeling, modification support, and cell line engineering. The platform is designed for flexible project execution, from early feasibility and screening-stage material preparation to larger-scale production and process-oriented programs, with clear documentation and application-ready deliverables.

Nebulabio’s expression modules are designed to support different target properties, folding requirements, and production objectives. Rather than using a single route for all projects, we organize expression workflows around the most suitable host and process logic for each protein program. 

• Protein Expression Services for construct-to-expression workflow planning, host selection, and expression optimization across multiple production systems.

• Mammalian Expression Systems for proteins requiring native-like folding, secretion, and post-translational processing, with HEK293- and CHO-based transient or stable workflows.

• Bacterial Expression Systems for efficient production of non-glycosylated proteins, domains, and enzymes, including soluble expression screening, tag strategy design, and inclusion-body recovery support.

• Baculovirus-Insect Cell Expression for eukaryotic proteins and complexes requiring balanced folding support and scalable expression in insect cell systems.

• Yeast Expression Systems for robust recombinant production using yeast hosts, with options for intracellular or secreted expression and fermentation-oriented process development.

• Cell-Free In Vitro Protein Expression for rapid feasibility studies, toxic targets, or fast prototyping workflows where cell-based expression is not preferred.

• Serum-Free Expression System workflows for compatible mammalian production programs requiring defined media conditions and process consistency.

These modules can be used independently or combined with downstream purification, labeling, and QC services as part of a single project package.

A reliable protein workflow depends on the connection between expression and downstream handling. Our downstream processing modules are organized to support purified, stable, and application-ready protein outputs for research and assay use.

• Protein Expression and Purification Services for integrated upstream and downstream execution, including expression optimization, harvest processing, purification design, and release-ready sample preparation.

• Protein Purification Platform for tag-based and tag-free purification strategies, polishing, buffer exchange, and preparation of assay-ready or storage-ready protein material.

• Protein Modification and Detection Platform for custom processing, conjugation support, and detection-oriented preparation aligned with project-specific assay or characterization needs.

• Protein Labeling services for fluorophore, biotin, enzyme, and other research-use labels, with post-labeling cleanup and verification support.

• Endotoxin-free Protein Production for projects requiring low-endotoxin protein material for sensitive cell-based workflows and in vivo-compatible research applications.

• Protein Extraction Services for recovery of proteins from cells, tissues, or other biological matrices, with lysis, clarification, and solubilization workflows adapted to sample type.

This integrated structure helps ensure that expression choices, purification methods, and downstream processing remain compatible throughout the project lifecycle.

Membrane proteins require dedicated workflows because of their hydrophobic domains, structural sensitivity, and solubilization requirements. Our membrane protein module is organized as a focused service group within the broader protein platform to support receptor, channel, transporter, and related target classes.

• Membrane Protein Services for project planning and workflow design covering construct optimization, host selection, extraction strategy, stabilization, and downstream handling.

• Membrane Proteins Expression and Purification for integrated membrane protein production workflows, including expression screening, detergent and buffer optimization, purification development, and stability-focused refinement.

These services can also be paired with labeling, modification, and custom cell line modules when membrane protein programs require assay-ready materials or target-specific expression systems.

Many projects require more than standard recombinant expression. Our platform includes construct-oriented and format-specific production modules for proteins that need fusion-assisted expression, Fc-based formats, or broader customization across multiple steps.

• SUMO-tag Protein Production for proteins that benefit from fusion-assisted soluble expression, tag-enabled purification, and optional cleavage workflows.

• Fc Fusion Protein Production for Fc-tagged proteins requiring robust expression, Protein A/G-compatible purification, and assay-friendly handling.

• Custom Protein Service for project-specific workflows that combine expression, purification, labeling, modification, extraction, or scale-up in a single customized service package.

This service group is designed for teams working with non-standard targets, specialized protein formats, or defined deliverable specifications.

Protein projects often evolve from exploratory work to larger and more structured production programs. Our scale-oriented service group supports that transition by maintaining a consistent workflow logic while expanding batch size, throughput, and process control.

• High-throughput Protein Production for parallel expression and purification of multiple constructs, variants, or domains in screening and optimization programs.

• Large-Scale Protein Production Service for scale-up from pilot or research batches to larger production runs with coordinated upstream and downstream execution.

• Industrial-Scale Customization Platform for process-focused projects requiring production customization, workflow standardization, and documentation-oriented program management.

These modules support teams that need continuity between early-stage protein preparation and larger, process-driven production planning.

Protein production and assay development often depend on stable and well-characterized cell systems. Our cell engineering module is integrated into the platform to support expression models, reporter systems, and edited cell lines that complement protein-related research programs.

• Stable Cell Line Services as an integrated umbrella for stable expression, reporter, knockdown, knock-in, and knockout workflows.

• Custom Gene Expression Cell Lines for constitutive or controlled target expression in selected host backgrounds for protein production and assay support.

• Custom Reporter Cell Line Generation for pathway-responsive or target-linked reporter systems used in screening and functional workflow development.

• Custom Gene Knockdown Cell Lines for loss-of-function studies with stable knockdown strategies and standard verification support.

• Stable Knock-in Cell Line Generation for defined genomic insertion of tags, reporters, mutations, or expression cassettes.

• Stable Knockout Cell Line Generation for gene disruption workflows used in functional studies, assay controls, and target validation.

• GPCR Stable Cell Line Development for receptor-focused expression and assay-ready cell model generation.

• Ion Channel Cell Line Development for stable ion channel expression systems compatible with downstream assay workflows.

This cell line service group allows clients to align protein production and cell-based assay resources within one coordinated project framework.
