Recovery/Purification TRIZ Cases
- AAV Vector Electroporation for Higher Virus Yield
Pulsed electroporation replaces reagent-based transfection to raise AAV yield and full capsid rate while simplifying large-scale virus production.
- Recombinant AAV Vector Production Using Repeated Transfection
Optimized plasmids and scheduled repeated transfections support scalable recombinant AAV production with fewer producer cells.
- Recombinant Bocavirus Vector for Helper-Free Replication
Mutations in non-structural proteins eliminate wild-type contamination while maintaining high titers.
- Recombinant Adenovirus 5' Terminal Sequence Homogeneity
Standardized adenovirus terminal nucleotide sequences resolve batch heterogeneity to enhance replication efficiency via molecular cloning.
- Adenovirus Purification via DNA Precipitation and TFF
Selective host cell DNA precipitation removes impurities before tangential flow filtration, achieving high virus recovery in a single clarification step.
- Vaccinia Virus Deletion Variants for Attenuation Analysis
Segmenting the vaccinia genome into specific deletion regions isolates genetic factors controlling replication competence and safety profiles.
- H-1 Parvovirus Purification via Isoelectric Point Separation
Anion exchange chromatography isolates full H-1 parvovirus particles from empty capsids using isoelectric point differences.
- Parvovirus Production via Low Cell Density Culture
Low cell density culture with serum-free medium yields high-titer parvovirus, eliminating complex ultracentrifugation steps.
- AAV Purification Using Surfactant and TFF
Surfactant treatment solubilizes hollow particles for removal via tangential flow filtration, preserving viral biological activity.
- Two-Stage PEG Precipitation for Non-Enveloped Virus Purification
A two-stage polyethylene glycol precipitation process purifies non-enveloped virus particles by separating impurities and viral components sequentially.
