FAQ

Frequently Asked Questions

Find answers to common questions about our service.

Insect cells offer several advantages over bacterial expression systems: proper protein folding in a eukaryotic environment, post-translational modifications including glycosylation, support for disulfide bond formation, and the ability to produce complex multi-subunit proteins and membrane proteins. The baculovirus expression system is particularly well-suited for producing virus-like particles and proteins requiring authentic mammalian-like processing.
Sf9 cells are ideal for general protein expression and baculovirus production, offering robust growth and good protein yields. High Five cells (derived from Trichoplusia ni) are preferred for secretory proteins and typically produce higher yields of secreted proteins. Our team can recommend the optimal cell line based on your specific protein type and application requirements.
We offer multiple affinity tags including His-tag (6xHis) for metal affinity chromatography, GST-tag for glutathione affinity purification, and MBP-tag for improved solubility and purification. Tags can be placed at N-terminus, C-terminus, or both depending on your protein requirements. Cleavable linkers with proteases like TEV or thrombin are available for tag removal after purification.
Standard service timeline is 3-4 weeks from gene delivery to purified protein. This includes subcloning, baculovirus generation (P1-P3 viruses), small-scale expression test, large-scale production, and affinity purification with QC. Premium service with additional purification steps (SEC, IEX) takes 4-6 weeks. Large-scale production for multi-gram yields requires 6-10 weeks depending on project complexity.
Yes, our insect cell expression platform is ideal for VLP production. The baculovirus system naturally supports assembly of multi-protein structures, making it the preferred choice for VLP-based vaccine development. We can co-express multiple structural proteins to generate authentic VLPs. Our platform supports both research-scale and GMP-compatible large-scale VLP production for preclinical studies.
Every batch undergoes comprehensive quality control including SDS-PAGE for purity assessment, western blot for identity confirmation, mass spectrometry for sequence verification, and endotoxin testing (LAL assay). Additional services include biological activity assays, size-exclusion chromatography for aggregate analysis, and glycosylation profiling. All results are provided in a Certificate of Analysis with your delivery.
