Golden spine shows shared workflow cues; drill into each lane for specificity.
- Process laneMammalian · HEK293
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.
Open architecture hub - Process laneMammalian · CHO
CHO lines align with bioprocess expectations for monoclonals and glycan-sensitive biologics, supporting stable pools or clone-scale programs.
Open architecture hub - Process laneProkaryotic · E. coli
Cost-effective E. coli induction cycles suit intracellular soluble domains, tagged antigens and high-throughput proof-of-expression screens.
Open architecture hub - Process laneBaculovirus / insect cells
The baculovirus–insect system handles challenging ECDs, phosphorylated substrates and multisubunit complexes with flexible titration windows.
