Nebulabio provide a premier High-throughput Protein Production service, delivering an industrialized and automated platform for the parallel expression and purification of hundreds to thousands of recombinant proteins. Designed to meet the massive scale demands of modern proteomics, structural genomics, and drug discovery pipelines, our service transforms genetic information into purified, QC-verified protein samples with unprecedented speed and consistency. By integrating automated molecular cloning, parallelized small-scale expression in multiple host systems (E. coli, insect, mammalian), and robotic liquid handling for purification, we eliminate the traditional bottlenecks of sequential protein production. We empower researchers in academia and industry to accelerate large-scale functional studies, screen protein libraries, and validate therapeutic targets by providing a reliable, scalable pipeline that matches the throughput of next-generation sequencing and high-content screening technologies.
☞Introduction to High-throughput Protein Production
High-throughput Protein Production is a systematic, industrialized approach to generating numerous recombinant protein constructs in parallel, rather than one at a time. This paradigm shift is essential for projects where scale and speed are critical, such as:
● Proteome-scale Studies: Generating protein libraries to represent a significant fraction of an organism's proteome for functional annotation.
● Antibody and Binder Discovery: Expressing hundreds of potential antigen targets or antibody variants for rapid screening campaigns.
● Structural Biology Initiatives: Producing multiple homologs, truncations, or point mutants of a target protein to identify constructs amenable to crystallization or Cryo-EM.
● Enzyme and Pathway Analysis: Creating comprehensive mutant libraries for directed evolution or metabolic pathway reconstitution.
Our platform is built on miniaturization, automation, and standardization. Reactions are conducted in microtiter plates (96, 384-well format), and every step—from plasmid preparation and cell culture to lysis and purification—is performed by robotic workstations. This ensures not only high throughput but also exceptional reproducibility and minimal sample-to-sample variation, which is crucial for comparative analysis.

☞High-throughput Protein Production Process
Our optimized, multi-stage workflow is engineered for maximum parallel processing efficiency without compromising protein quality.
Phase 1: Cloning & Construct Management ● Gene Synthesis/Amplification: Target sequences are codon-optimized and synthesized or PCR-amplified in parallel. ● Automated Cloning: Using liquid handlers, genes are simultaneously cloned into a panel of expression vectors (with various tags: His, GST, MBP, etc.) via restriction-ligation or recombination-based methods. ● Clone Verification: Plasmid DNA is prepared in high-density plate formats and verified by automated colony PCR or sequencing. |
Phase 2: Parallel Expression & Screening ● Host Transformation/Transfection: Expression vectors are transformed into E. coli or transfected into insect (baculovirus) or mammalian (HEK293) cells in 96-deep well blocks. ● Micro-scale Expression: Small-scale cultures are grown under standardized, yet condition-optimized protocols (e.g., varying temperature, inducer concentration) to screen for soluble expression. ● Expression Analysis: A fraction of each culture is lysed, and total and soluble protein expression is analyzed by automated SDS-PAGE (e.g., using capillary electrophoresis systems) or dot-blot to identify the best-performing constructs and conditions. |
Phase 3: Automated Micro-purification ● Culture Scale-up & Harvest: Positive expression cultures are scaled up in deep-well plates, and cells are harvested by micro-centrifugation or filtration. ● Robotic Purification: Cell pellets are resuspended and lysed robotically. The lysates are then processed for affinity purification. For His-tagged proteins, this typically involves binding to nickel-chelate resin in filter plates, followed by automated wash and elution steps. ● Buffer Exchange & Normalization: Eluted proteins are simultaneously desalted and transferred into a standard storage buffer (e.g., PBS or Tris). Protein concentrations are normalized based on absorbance measurements. |
Phase 4: Quality Control & Delivery ● High-throughput QC: A sample from each purified protein undergoes rapid quality assessment. This includes: ①Concentration Check: UV absorbance measurement. ②Purity & Integrity Analysis: Automated capillary electrophoresis (CE-SDS) or microfluidic gel systems. ③Identity Confirmation: Optional mass spectrometry analysis on key samples. ● Plate-based Storage & Shipment: The final purified, QC-checked proteins are arrayed in microtiter plates, sealed, and shipped on cold packs along with a comprehensive data file mapping well positions to protein identity, sequence, yield, and QC metrics. |
