Frequently Asked Questions

Find answers to common questions about our insect cell expression services.

What types of proteins can be produced in insect cells?

Insect cells are excellent hosts for a wide range of proteins including cytoplasmic proteins, secreted proteins, membrane proteins (GPCRs, ion channels), viral proteins, enzyme complexes, virus-like particles (VLPs), and post-translationally modified proteins. The system provides authentic folding and modification machinery while maintaining high expression levels.

How does insect cell glycosylation compare to mammalian cells?

Insect cells produce N-glycans with a paucid-mannosidic structure, which is simpler than the complex N-glycans seen in mammalian cells. However, High Five cells generate more mammalian-like glycan structures. For applications requiring human-type glycosylation, our glycoengineering services can produce humanized glycan profiles with terminal sialic acids when needed.

What is the typical yield from insect cell expression?

Expression yields vary depending on the protein, cell line, and expression conditions. Typical yields range from 1-50 mg/L for secreted proteins and up to 100+ mg/L for intracellular proteins. Our screening process identifies optimal conditions to maximize your specific protein yield. We routinely achieve >90% purity in final preparations.

What is the difference between Sf9, Sf21, and High Five cells?

Sf9 and Sf21 (both from Spodoptera frugiperda) are closely related cell lines with high virus titers and robust growth, ideal for general expression and virus production. High Five cells (from Trichoplusia ni) offer superior secretion efficiency and more mammalian-like glycosylation, making them preferred for secreted proteins and complex eukaryotic proteins. We test multiple cell lines to select the optimal host for your protein.

Can you produce proteins under GMP conditions?

Yes, we offer GMP-compliant manufacturing services for clinical and commercial applications. Our facilities maintain strict quality systems with comprehensive documentation, raw material controls, and process validation. GMP production includes full regulatory support and documentation packages for IND/BLA submissions.

What quality control tests are included?

Standard QC includes SDS-PAGE analysis, Western blot verification, mass spectrometry (LC-MS) for identity confirmation, SEC-MALS for aggregation analysis, endotoxin testing, and virus titer determination. Additional tests such as HPLC purity, biological activity assays, and residual DNA quantification are available based on your requirements.

How do you handle difficult-to-express proteins?

For challenging proteins, we employ multiple strategies: construct screening (signal peptides, tags, truncation), alternative cell lines, temperature shift protocols, novel promoter systems, and co-expression of folding helpers. Our extensive experience with membrane proteins, multi-subunit complexes, and toxic proteins ensures we can optimize conditions for even the most challenging targets.

What are the storage and stability requirements?

Purified proteins are typically shipped frozen on dry ice and should be stored at -80°C for long-term stability. Buffer composition and additives (glycerol, sucrose) can be optimized for your downstream application. We provide stability recommendations and can perform freeze-thaw studies to validate storage conditions for your specific protein.

Do you offer custom cell line development?

Yes, we offer custom insect cell line development services including glycoengineered cell lines for humanized glycosylation, stable cell lines for consistent production, and customer-provided cell line adaptation. Our R&D team can develop tailored solutions for specific product requirements.
