From protein design to production data.

PandaPure is Ailurus Bio’s purification technology. It uses programmable synthetic organelles inside E. coli to capture target proteins and support their recovery in an automation-friendly workflow.

Ailurus provides the technology; Shenzhen Synthetic Biology Infrastructure adapts and runs the automated, high-throughput expression and small-scale purification workflow. Together, we bring PandaPure to the cloud.

Each construct includes DNA design and construction, two independent PandaPure expression and purification runs, applicable absorbance/fluorescence measurements per run, and SDS-PAGE on one selected run per construct where sufficient protein is recovered for detection.

Products below the detection threshold are reported as such. You receive plasmid GenBank files, optical readouts and applicable SDS-PAGE results to compare expression, purification and solubility under the tested conditions. These results help identify candidates worth taking forward; they do not establish protein function or guarantee performance at another scale.

Standard starts at one construct. Once construction is complete, ready constructs join the experimental queue first come, first out.

Batch offers lower prices for projects with flexible timing. Order in multiples of 96 constructs; each group enters experiments together. Both modes include the same two independent runs per construct. For projects with more than 768 proteins, contact support@ailurus.bio directly to coordinate DNA construction capacity and scheduling.

Our AI models select one optimized CDS (DNA coding sequence) and one vector per protein by default. Increase CDSs to compare codon optimizations, or vectors to compare expression vectors. Each combination is one construct: 2 CDSs × 3 vectors gives 6 constructs. Blank counts default to 1.

Only the target protein CDS is charged, estimated as amino-acid count × 3. Short uses a fixed price up to 1,000 bp; Long uses the per-bp rate above 1,000 bp and up to 5,000 bp. Longer CDSs are quoted on request. Vector backbone and vector-provided tags and linkers are excluded.

A new CDS is charged at its Short or Long rate. Reusing it in another vector costs only the Short minimum: US$120 in Standard or US$90 in Batch. The calculator assumes reuse within each protein row, subject to design review. Different codon optimizations are separate CDSs; identical protein sequences across rows do not automatically count as reusable DNA. Prices exclude applicable taxes.

Two independent runs are included per construct. Add more using “Additional runs per construct” at US$10 per run per construct in either mode.

Each extra run adds another culture and applicable absorbance/fluorescence measurements, without new DNA synthesis or additional SDS-PAGE. Extra runs do not count toward the 96-construct Batch requirement.

We review your sequences and requested designs, then confirm scope, CDS reuse, price and schedule in a quote before work begins. Extra-long CDSs and custom requirements are reviewed individually. Results are reported weekly once experiments are underway.

Sequences are used to review and perform your project; results are shared with your project contacts. Tell us before submitting confidential information if you need an NDA or specific data-handling arrangements. See our privacy policy.
