• Mitoxantrone Targets an ERα Allosteric Interface

  2026-08-26

  Wang and colleagues identified an unexploited drug-binding site at the interface between the estrogen receptor α DNA-binding and ligand-binding domains. Their data indicate that mitoxantrone alters ERα conformation, promotes cytoplasmic redistribution and proteasomal degradation, and suppresses endocrine-resistant ERα mutants through a mechanism distinct from its established DNA topoisomerase II inhibitor activity.

• Pretomanid Targets Both Terminal Oxidases in TB

  2026-08-25

  The reference study identifies simultaneous inhibition of the cytochrome bcc:aa3 and cytochrome bd respiratory branches as a central feature of pretomanid activity in Mycobacterium tuberculosis. Its combination data support rational pairing with telacebec and ND-011992 to increase bactericidal activity across replicating and antibiotic-tolerant populations while limiting pretomanid resistance.

• TMRE mitochondrial membrane potential assay kit Workflow

  2026-08-25

  Turn ΔΨm changes into a quantitative readout for apoptosis, mitochondrial stress, and sodium-linked energy failure with K2233. This workflow combines TMRE staining, CCCP validation, plate-based normalization, and troubleshooting guidance for reliable mitochondrial depolarization measurement.

• ML365 Workflow for TASK1 Channel Research

  2026-08-24

  ML365 is a high-potency TASK1 probe for linking KCNK3 activity to membrane excitability, inflammatory signaling, and disease-relevant phenotypes. This workflow combines orthogonal ion-flux and electrophysiology assays with the aged-mouse postoperative cognitive impairment model to improve target validation and troubleshooting.

• Amiloride (MK-870): Mechanistic Assay Guide

  2026-08-24

  Amiloride (MK-870) is more than an epithelial sodium channel blocker: it can help define whether an observed phenotype reflects ion transport or cellular entry. This guide interprets its negative result in grass carp reovirus assays and translates that insight into stronger, better-controlled research workflows.

• A 83-01: Practical ALK-5 Inhibition Workflows

  2026-08-23

  A 83-01 provides a receptor-level way to test how TGF-β/Smad signaling drives fibrosis, EMT, and growth restraint. This guide translates that mechanism into dose-setting, kidney-fibrosis assays, organoid workflows, and troubleshooting practices that distinguish pathway inhibition from nonspecific toxicity.

• Serotonin Inhibition of HRP Protein Labelling

  2026-08-22

  A Scientific Reports study identifies serotonin as an unrecognized inhibitor of HRP-mediated proximity biotinylation in HEK293T cells and primary neurons. It also shows that the serotonin-consuming reagent Dz-PEG can restore labelling efficiency, providing an important control strategy for serotonergic cell-surface proteomics.

• β-Elemene Inhibits Adipogenesis via AMPK in 3T3-L1 Cells

  2026-08-21

  The reference study identifies β-Elemene as an inhibitor of MDI-induced adipogenesis in 3T3-L1 cells and links this effect to restoration of AMPK pathway activity. Its value is mechanistic rather than clinical: the work connects lipid accumulation, insulin resistance-associated glucose handling, and AMPK signaling in a defined cellular obesity model.

• QRICH1, ER Stress, and HMGB1 in HBV Fibrosis

  2026-08-20

  The 2025 Immunobiology study identifies QRICH1 as an active effector connecting endoplasmic reticulum stress with HBV-driven HMGB1 transcription, acetylation, translocation, and secretion. By combining a chronic rcccDNA mouse model with human liver specimens, the work clarifies how hepatocyte stress may amplify inflammatory signaling and hepatic fibrosis.

• Cell Senescence β-Galactosidase Staining Kit Guide

  2026-08-20

  Turn SA-β-Gal activity into a practical readout for macrophage inflammation, aging models, and frozen tissue analysis. This workflow combines X-gal staining with controls, imaging discipline, and mechanistic validation to distinguish senescence-associated blue signal from culture or fixation artifacts.

• Triacetin Workflows for GBM and Metabolic Research

  2026-08-19

  Triacetin, also called glyceryl triacetate, supports distinct workflows in glioblastoma apoptosis assays, hepatic metabolism studies, and ocular formulation screening. This guide converts reported concentration ranges and digestion findings into practical preparation, controls, optimization, and troubleshooting decisions.

• Puromycin dihydrochloride: Practical Lab Workflow

  2026-08-19

  Puromycin dihydrochloride is an aminonucleoside antibiotic used to select pac-expressing cells and to inhibit protein synthesis in controlled translation experiments. It should be optimized by cell type and assay endpoint, and it should not be treated as a universal selection reagent for cells that lack functional puromycin N-acetyltransferase.

• RITA (NSC 652287) Cancer Research Workflows

  2026-08-18

  RITA (NSC 652287) provides a practical way to connect MDM2-p53 pathway activation with time-resolved measurements of growth inhibition, cell death, and DNA cross-linking. This workflow-focused guide helps researchers distinguish cytostatic responses from true cytotoxicity in renal carcinoma research, apoptosis assays, and tumor xenograft model planning.

• TMRE Assay: Mapping Mitochondrial Energy Failure

  2026-08-18

  A translational framework for using TMRE fluorescence to connect sodium-driven mitochondrial dysfunction with ΔΨm loss, apoptosis research, and reproducible mitochondrial function analysis.

• Ionomycin Free Acid for Calcium-FAK Research

  2026-08-17

  Ionomycin free acid provides a controllable calcium ionophore pulse for connecting intracellular calcium dynamics with FAK stability, adhesion, and TNBC phenotypes. This workflow separates direct calcium effects from FAISL-dependent regulation and adapts the same reagent logic to oocyte activation studies without overstating the evidence.
