• DNase I and Translational RNA Integrity

  2026-10-04

  A thought-leadership perspective on how DNA removal, RNA integrity, and sample provenance influence translational oncology models, with mechanistic context for DNase I (RNase-free) and evidence from patient-specific pancreatic cancer organoid–fibroblast research.

• Regorafenib in Cancer Biology: Evidence and Limits

  2026-10-03

  Regorafenib, also known as BAY 73-4506, is a multikinase inhibitor studied in angiogenesis and oncology research.

• Standardized Whole-Blood Stimulation for Immunometabolism

  2026-09-28

  Zhao and colleagues describe a standardized whole-blood stimulation protocol that combines pathogen-associated immune challenges with pharmacological modulation of cellular metabolism. The workflow links cytokine measurements to metabolic pathway activity, offering a practical platform for cohort studies and mechanistic immunometabolism research while highlighting the need for careful controls and interpretation.

• Sensitive UHPLC–MS/MS for Methylated Purines

  2026-09-28

  Zhang, Zhang, and Wang developed a stable isotope-dilution UHPLC–ESI-MS/MS method for measuring 12 purine ribonucleosides, including 10 methylated species. Ammonium bicarbonate-enhanced ionization, chromatographic separation of isomers, and sample cleanup helped address sensitivity and matrix-interference problems in cellular measurements.

• Steroid-Induced Protoplast Lysis: 1965 Study Insights

  2026-09-27

  Smith and Shay used osmotically fragile Sarcina lutea protoplasts to test whether synthetic antimicrobial steroids could damage cells independently of the cell wall. Their findings—including steroid-associated lysis and its modification by polyamines, ions, and surfactants—support direct membrane effects as a likely contributor, while leaving the precise molecular mechanism unresolved.

• Vasopressin Analogues: Mechanisms and Therapeutic Scope

  2026-09-26

  Glavaš and colleagues review how structural variation in vasopressin analogues can shift receptor activity, stability, and therapeutic use. Their synthesis places lypressin alongside better-characterized analogues while emphasizing that proposed newer applications, including antiviral activity, require stronger experimental validation.

• 5-Methyl-CTP for Reliable mRNA-Based Cell Assays

  2026-09-25

  Learn where 5-Methyl-CTP (SKU B7967) fits in mRNA workflows that feed into cell viability, proliferation, or cytotoxicity studies. This practical guide covers experimental controls, product specifications, handling, interpretation, and vendor selection without confusing an IVT reagent with a direct cell-assay reagent.

• TUNEL Assays in Spinal Cord Repair Research

  2026-09-25

  How translational researchers can use DNA-fragmentation measurements to interpret cell death alongside vascular repair and blood-spinal cord barrier outcomes after injury.

• Novobiocin Sodium: Assays & Workflows
