Custom Recombinant Protein Expression Services
High-Purity, Biological Active Protein for Research & Diagnostic Applications
With over 20 years of experience, IMD provides comprehensive "one-stop" recombinant protein expression services—from gene synthesis to purified proteins. We have established multiple expression systems (bacterial, baculovirus-insect cell, yeast, and mammalian), over 20 purification strategies, and a wealth of in-house protocols for expression optimization. Our technical team works closely with you, delivering timely reports and high-quality proteins tailored to your specific needs.
Our Services
1
Bacterial Expression System (E. coli)
Multiple expression vectors and bacterial strains to meet diverse requirements. Various strategies to enhance solubility, activity, and productivity of target proteins. High-throughput and medium-scale expression and purification capabilities. Fast turnaround (~4 weeks) delivering ready-to-use proteins (several mg) at a cost-effective price.
2
Mammalian Cell Expression System
Multiple cell lines available, including HEK293, CHO, and CHO-S. Transient or stable expression with optimized systems to maximize yield. Adhesion or suspension culture with large-scale fermentation capabilities. Ideal for complex proteins requiring proper folding and mammalian post-translational modifications.
3
Insect Cell Expression System (Baculovirus)
Efficient expression of intracellular and extracellular proteins.
Multiple insect cell lines available, including Sf9, Sf21, and Hi-5. High-efficiency expression with extensive experience in packaging high-titer baculoviruses. High-throughput expression capable of producing complex proteins with post-translational modifications. Suitable for both intracellular and secreted protein targets.
4
Yeast Expression System (P. pastoris & S. cerevisiae)
The most cost-effective eukaryotic protein expression system available. Different strains of P. pastoris and S. cerevisiae for expression optimization. Innovative methods to select stable clones with high protein expression yields. Fast turnaround (~7–8 weeks) with high-throughput expression and purification.
