Benefits

 
speed to clinic
Increase speed to clinic and manufacturing milestones

Save 6-18 months in your protein therapeutic development timeline with access to our cloud-connected bioreactor facility. Instead of dedicating time and resources to building your own lab infrastructure, focus on advancing your protein therapeutic pipeline. Our streamlined workflows and advanced systems are purpose-built to accelerate key milestones in clinic and manufacturing, helping you bring innovative therapies to market faster.

upstream process
Purpose-built to support protein therapeutic upstream process development

Our bioreactors are specifically designed for high-density, fed-batch microbial and mammalian upstream therapeutics processes, making them ideal for protein therapeutic development. Whether you are working on early-stage process optimization or scaling for production, our platform delivers precise control and consistency, ensuring robust and reliable upstream results. This specialized design helps biotech and pharmaceutical teams achieve superior outcomes with less effort and complexity.

 
fermentation
Scale fermentation without infrastructure delays

Skip the time and cost of lab build-outs. Our cloud-connected bioreactors (250mL and 5L) provide on-demand fermentation capacity, while Stratyx250 enables in-house process testing for early-stage development.

Capabilities

 
cell-lines
Modality suites for a range of cell lines

We offer comprehensive expertise across a wide variety of cell lines, including CHO, HEK, yeast, and E. coli, as well as many other platforms commonly used in protein therapeutic production. Our versatile modality suites are designed to support diverse biological systems, enabling seamless adaptation to the unique requirements of your project. Whether you’re working with mammalian cells for complex protein expression or microbial systems for high-yield production, our tailored solutions ensure reliable scalability and efficiency throughout your process.

protein analytics
In-house protein analytics for faster process development

Accelerate your development timelines with our integrated protein analytics. Culture provides in-house tools such as Size Exclusion Chromatography (SEC) for detailed product attribute analysis, IgG titer measurements for rapid quality assessments, and protein mass spectroscopy to precisely characterize molecular weight and structural integrity. We also offer process monitoring capabilities, including viable cell density (VCD), pH, and metabolite tracking, to deliver real-time insights into process performance. By combining analytical precision with process expertise, we help you optimize your workflows and achieve consistent, high-quality results.

 
clinical stage
Services tailored to clinical stage

Whether you’re in preclinical development or preparing for late-phase clinical trials, we offer a full range of services to meet your specific needs. From clone screening for early-stage development to detailed process characterization for regulatory submission, our platform supports every step of your journey. With flexible, scalable solutions designed for clinical-stage protein therapeutics, efficiently navigate the complexities of process development and achieve key milestones with confidence.

Service packages

Whether you want to work with Culture on a continuous or per project basis, we have a service package tailored to your specific goals.

Clone, strain & construct screening

Bioprocess modeling and simulation

Scaling a bioprocess from R&D to manufacturing is challenging. Bioprocess modeling and simulation enables precise control over process conditions, improving efficiency and reducing variability. Our services offer a bioprocess digital twin approach to streamline development, leveraging advanced modeling to simulate and optimize conditions before running costly experiments.

Bioreactor scale-out

Run multiple experiments using our parallel bioreactor systems, which are cloud-connected 250mL and 5L bioreactors managed in our facility for high-throughput optimization to ensure process consistency, accelerated development, and seamless scalability. For those seeking an in-house solution, Stratyx250 provides a disposable 250mL bioreactor that users can implement directly in their own labs for greater control. While you will be limited on the number of experiments you can run on your own, you can pair our Stratyx platform running in your lab with the bioreactors running in ours.
