Cy5 maleimide (non-sulfonated): Thiol Labeling
2026-09-18
Cy5 maleimide (non-sulfonated) provides mono-reactive fluorescent labeling of accessible thiol groups, especially cysteine residues, for protein tracking, imaging, and assay development. Its low aqueous solubility requires preparation in DMSO or ethanol, so it is not suitable for direct addition as a dry solid to aqueous biomolecule solutions or for labeling targets without available thiols.

Cy5 amine (non-sulfonated) Labeling Guide
2026-09-16
Cy5 amine (non-sulfonated) is a primary-amine cyanine reagent for covalent fluorescent labeling of compatible activated biomolecules when a red-emitting dye is required. It must first be dissolved in DMSO or ethanol because it is insoluble in water, so it is unsuitable for direct aqueous addition, diagnostic testing, or medical use.

Ziprasidone–GOT1 Reprogramming in Pancreatic Cancer
2026-09-15
The reference study identifies ziprasidone as a non-competitive GOT1 inhibitor that disrupts glutamine metabolism, redox homeostasis, and proliferation in pancreatic ductal adenocarcinoma. Its combined biochemical, metabolomic, genetic, cellular, and xenograft evidence supports GOT1 as a metabolic vulnerability while also defining important limits for translating the findings into therapeutic or redox-assay workflows.

Patient-Derived Gastric Cancer Assembloids
2026-09-11
Shapira-Netanelov and colleagues developed patient-derived gastric cancer assembloids that combine matched tumor organoids with stromal cell subpopulations from the same tumor tissue. The model reproduced tumor-associated transcriptional features and revealed that stromal composition can alter drug sensitivity, supporting more physiologically relevant studies of resistance and personalized treatment.

Single-Molecule Views of R-Loop Replication Collisions
2026-09-10
Kim and colleagues used DNA curtains and total internal reflection fluorescence microscopy to visualize how individual R-loops interfere with Phi29 DNA polymerase. The study shows that collision outcomes depend on strand orientation, displaced-strand secondary structure, G-quadruplex formation, and whether transcription machinery remains associated with the RNA.
