AtaGenix Laboratories
AtaGenix provides cost-effective, high-yield E. coli recombinant protein expression services — from gene synthesis to purified protein. Our systematic approach screens up to 32 expression conditions (strain, temperature, IPTG concentration, induction time) to identify the optimal parameters for your target protein.
Whether you need microgram quantities for initial characterization or gram-scale production for in vivo studies, our prokaryotic platform delivers with turnaround as fast as 2–3 weeks. PhD-level scientists manage every project with rigorous QC at each stage.
E. coli expression is ideal for non-glycosylated proteins, antigens, enzyme targets, and structural biology applications where speed and cost-efficiency are priorities. For targets requiring mammalian post-translational modifications, explore our Mammalian Expression Services.
Our standardized pipeline takes your gene sequence from design through to purified, QC-verified protein — with expert optimization at every step.
Service Scope
| ✓ Codon-optimized gene synthesis | ✓ Vector construction & sequence verification |
| ✓ Multi-strain transformation (BL21, Rosetta, SHuffle, etc.) | ✓ Up to 32 expression condition screens |
| ✓ Soluble & inclusion body pathways | ✓ Inclusion body refolding optimization |

| Tag | Size | Advantage | Best For |
|---|---|---|---|
| His (6x) | ~1 kDa | Minimal size impact, simple Ni-NTA purification | General use, structural studies |
| GST | ~26 kDa | Enhances solubility, mild elution | Solubility-challenged proteins |
| MBP | ~42 kDa | Strongest solubility enhancement | Difficult-to-express targets |
| SUMO | ~12 kDa | Clean cleavage, native N-terminus | Tag-free final protein |
Timelines and yields depend on target protein properties. Our scientists will recommend the optimal tag, strain, and expression strategy during project consultation. Quote-based pricing.
Explore real-world yeast protein expression case studies from AtaGenix. Our Pichia pastoris and Saccharomyces cerevisiae platforms deliver high-yield recombinant proteins with proper folding and glycosylation — supporting enzyme production, diagnostic antigen development, and antibody screening applications.
AtaGenix provides highly specific anti-tauN368 monoclonal antibodies to support Alzheimer’s disease research using the hTau368 transgenic mouse model. These antibodies enable precise detection of truncated tau fragments in Western blot and immunofluorescence experiments, validating tau accumulation, phosphorylation, and associated cognitive deficits in the hippocampus. With exceptional specificity and stability, AtaGenix’s solutions empower researchers to explore tau pathology mechanisms and advance tau-targeted therapeutic development.
