DNA Preparation TRIZ Cases
- Ribosomal RNA Origami Nanostructures for Cost-Effective Production
Replacing expensive DNA scaffolds with abundant ribosomal RNA reduces production costs while maintaining nanoscale structural precision.
- ssRNA Purification via Temperature-Gradient Anion Exchange
Elevated temperature elutes large mRNA from anion exchangers, removing contaminants at ambient temperature to achieve ultra-purity.
- Emulsion-Based Nuclease Screening for Off-Target Specificity
Segmented emulsion droplets isolate individual transcription reactions to measure target site specificity and minimize off-target cuts.
- Activating Transposon Mutagenesis for Bacterial Gene Identification
Activating transposons identify advantageous genes in bacterial strains through targeted transcription enhancement.
- TGFβ Inhibitors Shift DNA Repair Balance to Homologous Recombination
Administering TGFβ inhibitors shifts cellular DNA repair balance from nonhomologous end joining toward homologous recombination.
- Continuous mRNA Purification via Precipitation Filtration
Continuous precipitation and filtration remove chromatography binding limits, increasing manufacturing efficiency while maintaining purity.
- Oligonucleotide UF/DF Salt Control via Competitive Buffer
Competitive ammonium acetate buffers in ultrafiltration diafiltration control sodium and acetate levels, eliminating solvent precipitation steps.
