Pichia pastoris Protein Expression

With more than 15 years of dedicated Pichia pastoris expertise, and hundreds of customer projects successfully completed, VALIDOGEN combines technology leadership with a proven track record of industrial implementation. Processes developed using our platform have been successfully transferred to GMP manufacturing at 100,000 L and industrial production volumes of up to 200,000 L, enabling reliable commercial manufacturing.

VALIDOGEN has achieved recombinant protein titers of up to 45 g/L through targeted strain engineering, fermentation development, and process optimization. Leveraging more than 15 years of Pichia expertise, our team systematically optimizes cultivation conditions, fed-batch strategies, and induction protocols to maximize productivity, space-time yield, and manufacturing efficiency.

 

Extensively validated platform protocols, refined through more than 15 years of dedicated Pichia expertise, provide a robust foundation for scalable, high-performance, and cost-efficient Pichia pastoris (Komagataella phaffii) fermentation. By systematically optimizing cultivation conditions, fed-batch feeding strategies, and induction parameters for each production strain, VALIDOGEN has achieved up to 5-fold titer improvements beyond already high-performing platform processes, maximizing productivity while reducing manufacturing costs.

VALIDOGEN's proprietary UNLOCK PICHIA® platform supports both methanol-free and methanol-induced Pichia fermentation, enabling the selection of the optimal expression strategy for each protein and manufacturing scenario. The platform combines validated host strains, expression tools, and process development expertise to maximize flexibility, productivity, and process robustness.

Every project is developed with industrial implementation in mind. VALIDOGEN delivers comprehensive technology transfer packages including process descriptions, development data, optimization rationale, and operating parameters required for efficient implementation by internal manufacturing teams or CMOs, supporting smooth GMP and non-GMP process transfer.

We are a leading contract research & development organization specializing in recombinant protein expression using our exclusive UNLOCK PICHIA® protein expression technology. Our Pichia pastoris experts have been serving the protein production industry for more than 15 years.

With our UNLOCK PICHIA® platform we apply a broad portfolio of technologies for successful and economically viable expression of your protein in the yeast Pichia pastoris (also known as Komagataella phaffii). 

We offer lean expression feasibility studies including delivery of purified lab-scale protein samples, generate high-performance Pichia production strains in competitive time frames, develop scalable bioreactor cultivation protocols, and undertake protein purification process optimization. Services are complemented with technology transfer for smooth implementation at your facility or with your CMO.
