Services
Custom expression services across mammalian (transient HEK/CHO), baculovirus-mediated insect (Sf9/Tni), and E. coli systems; support for multiple antibody formats and scalable research-scale production with construct-level support.
Customizable purification workflows combining affinity and classical chromatographic techniques with analytical packages for characterization and qualification of protein deliverables.
Analytical services including baculovirus infectious titer determination, thermal shift (DSF) assays, intact mass analysis by LC-MS, colorimetric and fluorometric assays, and endotoxin testing to support process development and QC.
Advisory and documentation services informed by published best practices on construct generation, expression system selection, small-scale optimization, purification choices, and storage strategies for recombinant proteins and antigens.
