Vectors TRIZ Cases
- Self-Regulated Gene Expression via Ribozyme-Aptamer Cassette
A dual regulatory cassette merges bacterial repressors with ribozyme-aptamer modules to eliminate basal leakiness and minimize toxicity in gene therapy.
- Synthetic Promoter Intronic Sequence for Compact Gene Therapy Vectors
A synthetic promoter-associated intronic sequence enhances protein expression levels while maintaining a compact nucleic acid structure.
- Retroviral Vector WPRE Replacement for Safe Transgene Expression
Replacing Woodchuck Hepatitis Virus Post-Transcriptional Regulatory Element with spacer sequences in retroviral vectors.
- Podocin Promoter Drives Kidney-Specific TGFβ1 Expression in Transgenic Mice
A transgenic mouse model uses the Podocin promoter to drive kidney-specific human TGFβ1 expression.
- Episomal Vector Hematopoietic Stem Cell Generation
Episomal vectors transfect hemogenic endothelial cells to generate engraftable hematopoietic stem cells without insertional mutagenesis risks.
- MAR Sequence Expression Vector for Animal Cells
Incorporates human beta-globin MAR sequences into animal cell expression vectors to enhance transgene production.
- Foamy Viral Envelope Gene Mutations for Targeted Gene Transfer
Expression-optimized foamy viral envelope genes encode modified polypeptides with inactivated ubiquitination sites to boost pseudotyped vector infectivity.
- Lentivirus Vector for Persistent Beta-Globin Expression
A lentivirus vector delivers a modified beta-globin gene to hematopoietic progenitor cells for persistent protein production.
- Recombinant Protein Purification Using Dual Affinity Matrices
Dual affinity matrices separate target proteins from co-purifying contaminants by extracting host cell impurities via tagged essential proteins.
