Ipodix Yeast Expression System: Innovative Solutions for High-Efficiency Eukaryotic Protein Production

 

I. Technical Advantages: Six Core Values of the Yeast System

Ipodix has developed the next-generation ‌YeastXpress™‌ technology platform based on Pichia pastoris and Saccharomyces cerevisiae dual systems, overcoming traditional expression limitations to achieve high-yield, cost-effective eukaryotic protein production.

1.  High-Efficiency Expression

● Secretory expression yields of 2–10 g/L (5–20x higher than mammalian systems)

● Compatible with proteins ranging from 10 kDa to 300 kDa

2.  Precision Post-Translational Modifications

● Glycosylation similarity to HEK293 system: 85%

● Disulfide bond accuracy >95%, phosphorylation site precision >90%

3.  Cost-Effective Production

● Media costs reduced to 1/8 of mammalian cell systems

● Single-batch output in 30L fermenters meets kilogram-scale demands

4.  Flexible Compatibility

● Supports both intracellular and secretory expression modes

● Multi-copy tandem expression vector construction

5.  Stringent Quality Control

● Endotoxin levels <0.05 EU/μg (injection-grade standard)

● Batch-specific glycan analysis reports (MALDI-TOF verified)

6.  Rapid Delivery
