• Molidustat (BAY85-3934) HIF Assay Guide

  2026-09-19

  Molidustat (BAY85-3934) provides a controllable way to stabilize HIF and study erythropoietin stimulation without directly adding recombinant EPO. This guide translates its renal-anemia rationale into a practical hypoxic cardiomyocyte workflow built around the Septin4–VHL–HIF-1α mechanism.

• CA-074 Maps Lysosomal Cathepsin B in Necroptosis

  2026-09-18

  CA-074 is a selective cathepsin B inhibitor that helps separate lysosomal membrane permeabilization from downstream proteolytic death. This article translates recent MLKL–lysosome findings into practical assay design for cancer, neurotoxicity, and immune studies.

• Biotin Azide: Click Labeling for Wnt Studies

  2026-09-18

  Biotin Azide is a high-purity click-chemistry reagent for labeling terminal-alkyne biomolecules with a biotin handle. Its CuAAC-compatible design supports detection and affinity workflows, while the cited Fzd5 study provides a biological context for studying lipid-regulated Wnt signaling.

• Nav1.5 Ser571, Late INa, and the Aging Heart

  2026-09-17

  The 2024 reference study identifies phosphorylation of the cardiac sodium channel Nav1.5 at Ser571 as a mechanistic link between increased late sodium current, delayed ventricular repolarization, and age-related diastolic dysfunction. By comparing wild-type, phosphomimetic gain-of-function, and phosphoablated loss-of-function mice, the authors show that late INa is a modifiable determinant of myocardial relaxation rather than merely an electrophysiological correlate of aging.

• Caspase-3 Colorimetric Assay Kit Guide

  2026-09-17

  The Caspase-3 Colorimetric Assay Kit measures DEVD-dependent caspase-3 activity in biological lysates by detecting p-nitroaniline released from a chromogenic substrate. It is appropriate for endpoint apoptosis assays with a microtiter plate reader or spectrophotometer, but not for real-time live-cell monitoring or interpretation as a standalone proof of apoptosis.

• Sodium-Driven Mitochondrial Failure in NECSO

  2026-09-16

  Qiao et al. identify mitochondrial energy failure as a central mechanism linking TRPM4-mediated sodium influx to necrosis by sodium overload (NECSO). The study connects mitochondrial sodium accumulation, NCLX-dependent calcium loss, impaired oxidative phosphorylation and TCA-cycle activity, ATP depletion, Na/K-ATPase failure, and terminal cell swelling and lysis.

• Transcription Condensates Safeguard Genome Stability

  2026-09-16

  Marmolejo et al. identify a cell-cycle timer that forms transcription condensates at histone locus bodies during the G1/S transition and removes them through ATR–CHK1 signaling in mid-S phase. The work links condensate dissolution to control of linker histone H1.1 expression and prevention of replication-associated DNA damage, offering a mechanistic framework for studying transcription–replication coordination.

• Otilonium Bromide Research Workflows

  2026-09-15

  Build controlled cholinergic perturbation assays with Otilonium Bromide, from receptor signaling and calcium imaging to smooth muscle spasm research. Its defined concentration formats and orthogonal workflow design support reproducible neuroscience and gastrointestinal motility disorder models without confusing pharmacological evidence with computational predictions.

• Silymarin: Milk Thistle Extract Workflows

  2026-09-15

  Build more reproducible cell, biochemical, and preclinical assays with Silymarin, a mixture-aware milk thistle extract for oxidative injury, liver-cancer, metabolic, and antiviral studies. This guide pairs solvent control and orthogonal readouts with practical dose-ranging and troubleshooting decisions.

• FPS-ZM1: Practical RAGE Inhibitor Workflows

  2026-09-14

  Use FPS-ZM1 to isolate RAGE-dependent amyloid beta transport, neuronal stress, and neuroinflammatory signaling from broader metabolic effects. This workflow translates RAGE/POMC findings into practical CNS assays while distinguishing established product evidence from proposed experimental extensions.

• Bifendate (DDB): Mechanism-to-Assay Guide

  2026-09-14

  Bifendate (DDB) is a multifunctional hepatoprotection agent with reported effects on lipid metabolism and autophagy. This guide connects its molecular profile with evidence-aware assay design, dosing interpretation, and translational limitations.

• Naftifine HCl: Mechanism and Research Workflow

  2026-09-13

  Naftifine HCl is an allylamine antifungal agent that inhibits fungal squalene 2,3-epoxidase and disrupts ergosterol biosynthesis. This research-use workflow separates validated antifungal evidence from the distinct WNT5a/GSK3/β-catenin findings reported in muscle progenitor biology.

• RAB31 and the ESCRT-Independent Exosome Pathway

  2026-09-12

  The Cell Research study identifies RAB31 as a regulator of an ESCRT-independent route for exosome biogenesis. It shows that active RAB31 coordinates flotillin-dependent intraluminal vesicle formation and TBC1D2B-mediated suppression of RAB7, linking cargo sorting to protection of multivesicular endosomes from lysosomal degradation.

• Paroxetine Mesylate Research Workflows
