Neurospora crassa IPA Pathway and Auxin Biosynthesis
2026-08-22
The Sardar and Kempken study provides the first integrated genetic and biochemical characterization of an indole-3-pyruvic acid pathway for indole-3-acetic acid production in the non-pathogenic fungus Neurospora crassa. Its combination of computational gene identification, metabolite profiling, and targeted knockouts shows how IPA flux contributes to fungal auxin production and conidiation.

Ceftolozane Resistance: PK/PD Modeling in P. aeruginosa
2026-08-21
Deroche and colleagues combined engineered Pseudomonas aeruginosa mutants, sequential time-kill experiments, and semi-mechanistic PK/PD modeling to separate constitutive from adaptive resistance to ceftolozane/tazobactam. The study shows that AmpC G183D and AmpD H157Y have distinct but synergistic effects, offering a quantitative framework for interpreting resistance that conventional MIC testing cannot fully resolve.

Cy3 NHS ester (non-sulfonated) Workflow Guide
2026-08-17
Cy3 NHS ester (non-sulfonated) provides an orange fluorescent handle for amino-group labeling of proteins, peptides, and amine-modified oligonucleotides or DNA. It is appropriate when a workflow can tolerate DMSO or DMF, but it should not be treated as a water-soluble reagent or used for direct aqueous labeling of solvent-sensitive biomolecules.
