FAQ

Frequently Asked Questions

Find answers to common questions about our service.

HEK293 is ideal for rapid protein production, early-stage research, structural biology, and viral vector manufacturing due to fast turnaround (2-3 weeks) and high transfection efficiency. CHO cells are preferred for large-scale therapeutic protein production requiring optimized glycosylation profiles and established regulatory pathways. The choice depends on your timeline, scale, and quality requirements.
We offer multiple HEK293 derivatives: HEK293T (for viral vector production), HEK293F (suspension-adapted for scalable production), HEK293E (for stable expression), and HEK293 GnTI- (producing homogeneous N-glycans for structural biology). Each variant has specific advantages depending on your application requirements.
For transient expression, purified protein can be delivered in 2-3 weeks from gene receipt. Stable pool development takes 4-6 weeks, and stable clone development requires 8-12 weeks. Expedited services are available for urgent projects. The exact timeline depends on expression complexity and purification requirements.
Yes, we offer validated viral vector production services using HEK293 cells including AAV vectors, lentiviral vectors, and adenoviral vectors. Our platform supports both research-grade and GMP-grade production depending on your requirements. HEK293T cells are particularly well-suited for viral vector manufacturing.
We offer scalable production from 1mL (96-well format for screening) through 100L bioreactors. Suspension-adapted HEK293F cells enable seamless scale-up for larger production runs. Scale selection depends on your protein quantity needs and expression characteristics.
We offer multiple purification tags including His-tag (Ni-NTA affinity purification), FLAG-tag (Anti-FLAG affinity purification), MBP, GST, and Strep-tag. Tag selection depends on your protein characteristics and downstream applications. Untagged purification via size exclusion chromatography is also available for proteins that require tag removal.
For challenging proteins, we offer co-expression with chaperone plasmids, use of protease-deficient cell lines, and optimized culture conditions. We also provide codon optimization services and can test multiple expression strategies including different tags and signal peptides to maximize your chances of success.
Every project includes comprehensive documentation including SDS-PAGE analysis, Western blot verification, mass spectrometry identity confirmation, and SEC-HPLC purity assessment. Certificate of Analysis with all QC data is provided with each shipment. Additional characterization such as endotoxin testing and aggregation analysis is available upon request.
Yes, we maintain strict confidentiality for all customer projects. We operate under non-disclosure agreements and have robust data security protocols. Sequences are encrypted and stored securely. We do not use customer sequences for internal research or share them with third parties without explicit permission.
Yes, we provide codon optimization services to enhance expression levels in HEK293 cells. Our algorithms optimize codon usage, mRNA stability, and GC content while avoiding sequences that could cause issues. We can also incorporate patient-preferred codons for therapeutic protein development. Optimization typically improves expression by 2-10 fold depending on the original sequence.
Standard preparations typically have endotoxin levels below 10 EU/mg for research-grade proteins. For applications requiring lower endotoxin levels such as cell therapy or in vivo studies, we offer endotoxin removal services achieving levels below 1 EU/mg. We use LAL testing for accurate endotoxin quantification and can provide certificates of analysis with endotoxin data.
