Peptide Preparation Methods TRIZ Cases
- Radiopaque Peptide Crosslinkers for Imaging-Visible Hydrogels
Iodinated peptide crosslinkers raise hydrogel radiopacity for clearer imaging while preserving crosslink density in medical use.
- Site-Selective Antibody Labeling for Homogeneous ADC Synthesis
Proximity effect-based labeling enables homogeneous, high-yield antibody-drug conjugates without modifying native antibody production.
- Substituted Cyclodextrin Viral Inactivation for Biopharmaceutical Fluids
Substituted cyclodextrins such as HPBCD inactivate enveloped viruses in biopharmaceutical fluids while avoiding Triton X-100 handling and eco concerns.
- Cyclic Peptide Cyclization Positioning to Reduce Dimer By-Products
Shifting cyclic peptide cyclization to a specific position cuts cyclic dimer by-products, supports scale-up, and enables stable crystal forms.
- Cell-Free Protein Purification Using Fluorescence and Magnetic Beads
Fluorescence complementation and magnetic bead affinity purification replace gel-based analysis for faster protein yield and purity measurement.
- Multichromophore Labeling Compound With Linkers to Prevent Quenching
Spacer-linked phosphor moieties suppress self-association and energy transfer, keeping biomaterial fluorescence bright as dye loading increases.
- Multichromophore Label Compounds That Suppress Dye Self-Association
Rigid, low-cLogP linking groups between phosphor moieties suppress dye association and preserve fluorescence in labeled biomaterials.
- Transient-Protected Amino Acids for One-Pot Peptide Bond Synthesis
A transient silyl protection and allenone coupling route merges protection, condensation, and deprotection to cut peptide synthesis time and racemization.
- Fluorescent Labeling Compound Linkers That Prevent Dye Quenching
A proline-like 5-membered ring linker separates phosphor moieties to suppress self-association and preserve bright fluorescence in solution.
- Fluorescent Labeling Compound Linkers That Suppress Dye Association
Rigid, low-cLogP linkers between phosphor moieties suppress dye self-association and quenching, preserving fluorescence in labeled biomolecules.
- Neoglycoprotein Glycan Standards Using Streptavidin-Biotin Scaffolds
A streptavidin-biotin neoglycoprotein standard enables accurate, low-cost comparison and quantification of target glycan structures on proteins.
- Plant Protein Liquid Processing for Solubility and Digestibility
Combined protein deamidase and cellulase treatment improves plant protein liquid solubility, digestibility, and mineral solubility.
- Proteoglycan Endotoxin Reduction While Preserving Molecular Weight
A nonionic surfactant and chromatography step lower endotoxin in animal tissue-derived proteoglycan without degrading molecular weight.
- FAPI Synthesis Intermediate for Lower-Polarity Industrial Purification
A protected DOTA intermediate lowers polarity and avoids unstable DOTA-NHS, improving Evans blue modified FAPI yield and cost.
- Cyclic Peptide Cocrystallization Without Column Chromatography
Cocrystal formation with selected coformers and solvents simplifies cyclic peptide crystallization while avoiding column chromatography.
- Subtilisin BPN' Variants for Selective Peptide Coupling in Water
Specific subtilisin BPN' mutations shift peptide synthesis toward coupling over hydrolysis, improving rate, selectivity, and aqueous performance.
- Amidine Formation for Site-Selective Peptide Backbone Insertion
Alternative amide and thioamide activation avoids ring closure, enabling site-selective amidine insertion within Fmoc SPPS peptides.
- Bispecific Antibody Assembly via Reduction-Free Half-Antibody Exchange
Asymmetric Fc-destabilizing mutations enable reduction-free half-antibody exchange, improving bispecific antibody purity and yield.
- Multispecific polypeptide constructs having constrained CD3 binding and related methods and uses
A non-cleavable Fc-linked multispecific construct localizes CD3 engagement to antigen sites, boosting cytotoxicity while limiting systemic T-cell binding.
