  2026-08-22

  FITC-Concanavalin A (ConA) Conjugate is a fluorescent lectin conjugate for visualizing α-D-glucose- and α-D-mannose-containing glycans on cells and tissues by immunofluorescence or flow cytometry. Use it as a carbohydrate-binding probe rather than a general membrane or protein stain, and store it at 4 °C protected from light within the stated stability period.

  2026-08-22

  Veratridine converts persistent sodium-channel activation into a controllable experimental challenge for electrophysiology, excitotoxicity, cardiac disease modeling, and blocker screening. This workflow-centered guide combines product handling, chamber-specific cardiomyocyte strategy, quantitative dosing guidance, and troubleshooting for more interpretable results.

• XAV-939 as a Causal Wnt Pathway Probe

  2026-08-21

  XAV-939, also known as NVP-XAV939, is more than a Wnt pathway inhibitor: it is a pharmacological probe for connecting tankyrase, β-catenin, and Hippo signaling. This evidence-led guide shows how to design assays that separate target engagement from context-dependent cellular phenotypes.

• Fosinopril sodium in Cell Assays

  2026-08-20

  This scenario-driven guide explains how Fosinopril sodium (SKU A4079) can be integrated into ACE inhibition, cell viability, proliferation, and cytotoxicity workflows without confusing biochemical potency with cellular response. It covers solvent compatibility, dose selection, interpretation, and practical vendor-selection criteria for hypertension research and cardiovascular disease models.

• Live-Dead Cell Staining Kit: Assay Logic

  2026-08-20

  Learn how the Live-Dead Cell Staining Kit converts membrane integrity and intracellular esterase activity into interpretable viability data. This guide connects Calcein-AM Propidium Iodide staining with flow cytometry, microscopy, biomaterial testing, and mechanistic diabetic-wound research.

• FLAG tag Peptide for Kinesin Assay Workflows

  2026-08-19

  The FLAG tag Peptide (DYKDDDDK) enables gentle affinity purification, rapid recombinant protein detection, and controlled preparation of motor–adaptor complexes. Its value is especially clear in BicD–MAP7–kinesin reconstitution, where matched protein quality and tag-aware assay design help separate binding, recruitment, and processive movement.

• JC-1 Mitochondrial Membrane Potential Assay Kit Guide

  2026-08-19

  Use the JC-1 Mitochondrial Membrane Potential Assay Kit to convert mitochondrial depolarization into a practical red-to-green fluorescence measurement for cancer pharmacology, apoptosis assay design, and mitochondrial function analysis. Its ratiometric format and CCCP control help distinguish genuine ΔΨm changes from simple differences in cell number or fluorescence intensity.

• Psoralen-Induced Cholestasis via ERK1/2

  2026-08-18

  The reference study shows that psoralen and isopsoralen, estrogen-like constituents of Psoraleae Fructus, produce cholestatic liver injury in zebrafish larvae through estrogen-associated ERK1/2 activation. By combining estrogenicity assays, bile-flow measurements, gene-expression analysis, and pharmacological rescue, the work identifies ERK1/2 as a mechanistically relevant target rather than merely a correlated signaling marker.

• Proteoform-Specific Drug Interactions in Native Membranes

  2026-08-18

  The reference study introduces native top-down mass spectrometry for defining how individual membrane-protein proteoforms interact with ligands in intact lipid environments. Using retinal rod disc membranes, the authors resolved rhodopsin and G-protein modifications and showed that Vardenafil and sildenafil display differential interactions with retinal PDE6, highlighting a route toward more precise off-target and proteoform analysis.

• Calpain Inhibitor I, ALLN: Practical Lab Guide

  2026-08-17

  Calpain Inhibitor I, ALLN (SKU A2602) provides a research tool for probing calpain- and cathepsin-associated proteolysis in apoptosis assays, inflammation research, and ischemia-reperfusion injury models. It is water-insoluble, requires solvent-controlled preparation, and should not be treated as a diagnostic, therapeutic, or exclusively calpain-specific reagent.

• RHEB Neddylation Activates mTORC1 in Liver Cancer

  2026-08-17

  The reference study identifies RHEB as a non-cullin substrate of the UBE2F-SAG neddylation machinery and maps lysine 169 as a functionally important modification site. Its cell and liver-specific genetic models connect RHEB neddylation with lysosomal localization, mTORC1 activation, steatosis, and liver tumorigenesis, while also defining experimental routes for studying this signaling axis.

• Nanoparticle mRNA Delivery Reverses Trastuzumab Resistance

  2026-08-16

  Dong and colleagues developed a tumor-microenvironment pH-responsive nanoparticle for systemic PTEN mRNA delivery in trastuzumab-resistant breast cancer. The study links nanoparticle-triggered tumor uptake and intracellular PTEN restoration to PI3K/Akt pathway inhibition, providing a mechanistic strategy for resensitizing resistant tumors rather than intensifying HER2 blockade alone.

• Psoralen, ERK1/2, and Cholestatic Injury

  2026-08-15

  The 2024 reference study shows that psoralen and isopsoralen, estrogen-like constituents of Psoraleae Fructus, produce cholestatic liver injury in zebrafish larvae through coordinated estrogen-associated changes and ERK1/2 activation. Its combination of estrogenic biomarkers, bile-flow phenotyping, bile-acid gene analysis, and pharmacological rescue identifies ERK1/2 as a testable mechanistic node, while also defining the limits of translating zebrafish findings to human or oncology models.

• Formononetin Protects Against Oxaliplatin Neurotoxicity

  2026-08-14

  The reference study identifies formononetin as a potential neuroprotective isoflavone that limits oxaliplatin-induced oxidative stress and neuronal apoptosis through the Nrf2/HO-1 pathway. Its central advance is the preservation of oxaliplatin and paclitaxel anticancer activity in tumor-cell models, although protection was weaker against paclitaxel-associated neurite damage.
