Process architecture
Human HEK293 supports transient and stable expression—Puweituo Bio’s go-to mammalian host for secreted recombinant proteins, Fc fusions and many discovery-stage candidates.
Secreted proteins, mAb/Fab fragments, receptor ECDs, Fc-fusions, and soluble checkpoints that benefit from authentic human glycosylation cues.
Industrial sequence—swap copy with your internal GXP narrative when ready.
Landing pages that pair host trade-offs with concrete catalogue or application cues — keep exploratory science on public routes before RFQ escalation.
Summaries from IA platform hubs — current host highlighted in gold.
| Platform | QC highlights | Timeline cues | Open |
|---|---|---|---|
| Mammalian · HEK293 | Routine SDS-PAGE, SEC-HPLC and endotoxin data; BLI/Octet-style binding assays on demand, plus project-specific COAs. | Transient timelines depend on sequence complexity and scale; schedules are quoted after scientific and PM review. | Viewing |
| Mammalian · CHO | QC panels may include purity, glycan profiling, potency/binding assays, residuals and microbial attributes per program. | Stable cell line generation and upstream development vary by modality; milestones are mapped once the scope-of-work locks. | Open |
| Prokaryotic · E. coli | Solubility tiers drive lysis, refold or secretion strategies; purity and contaminant profiling follow the bespoke route. | Bacterial runs iterate quickly once constructs behave; timelines stretch when refolding optimization is needed. | Open |
| Baculovirus / insect cells | Key readouts span titer, purity, baculovirus/HCP residuals, plus binding or particle-integrity assays when justified. | BAC-to-titer timelines depend on vector optimization iterations; checkpoints are clarified during intake. | Open |
