PandaPure™ Protein Systems

Purification reinvented,

with 0 column, 0 bead, 0 proteases.

Don’t let the complexity of protein purification prevent you from using purified proteins in your research. PandaPure Protein Systems simplifies expression, purification, and integrated tag removal into a single workflow accessible to any lab.

The problem

What if...

protein purification can be much easier?

Affinity chromatography for protein purification has been around for more than 50 years. But for many labs, it still means instrument access, expensive consumables, protease cleanup, and workflows that depend on specialized purification expertise. That slows projects down and keeps pure proteins from becoming routine.

Meanwhile, cells already sort, separate, and release proteins through compartmentalized biological machinery. We asked a practical question: can that biological logic become a usable purification workflow for everyday research?

PandaPure is our answer.

How it works

The PandaPure workflow.

Discover how we seamlessly blend expression, purification, and tag removal.

Express & Sort.

Co-express protein targets and synthetic organelle building blocks. Synthetic organelles assemble inside the cell, and capture the targets specifically.

Harvest & Isolate.

Open the cell envelope, and release host cell components. The dense organelles are then isolated from soluble impurities with simple separation like centrifugation§.

Cleave & Recover.

Release the target from the organelle by PandaPure protein tag cleavage chemistry, and then collect the protein products from the supernatant by one final spin.

Explore the offerings
  • † "Co-expression" can be arranged in varied dynamics depending on the property of proteins and desired specification. Simultaneous co-expression is not necessary.
  • ‡ A variety of cell lysis is applicable, from mild condition using non-ionic detergent, to mechanical disruptions like sonication and homogenizer.
  • § A variety of separation techniques, like high-pressure filtration can be applied for high efficiency, yields, and purities. Insoluble cell debris will often stay in the same phase with organelles and will not affect the final results.
  • ¶ Tag cleavage is mediated by the PandaPure Protein Tag Cleaver in a proper pH at 8~9 and temperature from 25 up to 45°C. Default HEPES-based buffer is provided together with Tag Cleaver at PandaPure Protein Reagent Kits.

PandaPure™ Protein Reagent Kits

PandaPure Protein Reagent Kits provide coordinated components for tag cleavage and protein recovery reaction in the standard format. Each kit includes PandaPure Protein Tag Cleaver (250x stock) and PandaPure Protein Buffer (HEPES).

In a standard workflow, Tag Cleaver and Buffer can be used to prepare 1x PandaPure Protein Reagent to support protein recovery out of the synthetic organelles. The resulting reagent is compatible with common downstream applications, e.g., SDS-PAGE and Bradford assay analyses.

Compatible buffers, additives, and alternative handling strategies may be used after validation for specific targets and applications.

bioprogram economics

Turn expenses into an investment.

PandaPure Protein Systems fundamentally changes purification economics, shifting expenses from recurring resin-based consumables to a biological program that cells can regenerate for you.

The more you use, the more you save.

By shifting value away from specialized equipment and consumables, PandaPure makes purification easier to start and can drive lower marginal cost per additional run.

PandaPure & Environment

A smaller downstream footprint.

The same design logic that reduces purification overhead also significantly reduces material intensity and waste.

Smart logic. Zero resin.

PandaPure eliminates the necessity for chromatography resins, columns, and beads within the primary workflow, thereby removing one of the most material- and resource-intensive components of traditional purification processes.

Made by biology.

PandaPure employs synthetic organelles, designed from genetic codes, to undertake purification roles usually performed by external solid-phase substances. This strategy ensures that all utilized materials are biodegradable in the environment.

Less water. Less waste

PandaPure eliminates the need for resin washing, repeated buffer exchanges, and protease cleanup processes, thereby minimizing water consumption, reducing disposable plastic usage, and decreasing downstream process waste.

Frequently Asked Questions

PandaPure with confidence.

Get clear answers on how PandaPure accelerates your R&D.

How does PandaPure compare to chromatography?

PandaPure replaces expensive FPLC systems and columns with programmable biological organelles. This eliminates the need for solid supports, significantly reducing hands-on time, and can improve yields and purities.

What equipment do I need for PandaPure Protein Systems?

Just standard lab essentials, i.e., a centrifuge, pipettes, and an incubator, are enough to start PandaPure. No FPLC is required. To further scale it, you can apply bioreactors, liquid handlers, and filtration units.

Is this suitable for high-throughput workflows?

Yes. The protocol scales seamlessly to 96-well deep-well plates and is compatible with liquid handling automation (e.g., OT-2), making it ideal for library screening.

Does the tag removal leave residues?

The cleavage site ensures precise tag removal. C-terminal designs leave minimal residues (only one glycine), while N-terminal designs leave a short sequence.

What can I purify with PandaPure Protein Systems?

The current Protein Series is a generic design for producing recombinant proteins in E. coli. Systems for yeast, mammalian, and other hosts or targets are in development — subscribe to get the latest updates.

What lysis methods are compatible?

We validate a wide range of methods, including mechanical disruption and mild detergents. If you are new to protein purification, we recommend to adopt PandaPure Lysis Reagent to get an easy start.
