• Sulfo-NHS-Biotin for EVTPD Assay Design

  2026-08-17

  Discover how Sulfo-NHS-Biotin can strengthen extracellular-vesicle assay design by selectively marking accessible amines without permeabilizing intact cells. This article connects practical surface biotinylation with the receptor-independent EV degradation strategy reported in recent targeted protein degradation research.

• Angiotensin II: Practical Research Protocol

  2026-08-16

  This dossier-based guide explains how Angiotensin II (SKU A1042) can be prepared and applied in receptor, cell-based, and vascular remodeling workflows. It is intended for controlled scientific research, not diagnostic, therapeutic, or clinical use, and all benchmark conditions should be validated in the investigator’s assay system.

• Dual Metabolic Reprogramming for TNBC Ferroptosis

  2026-08-15

  The reference study develops an iron-containing metal-polyphenol nanoplatform that combines DHODH and GPX4 suppression with DGAT1 inhibition to overcome ferroptosis resistance in triple-negative breast cancer. Its central contribution is showing that brequinar can both sensitize cells to ferroptosis and promote lipid-droplet accumulation, creating a rationale for simultaneous lipid-metabolism intervention.

• IWP-2: A Cell-State-Aware Wnt Inhibitor Guide

  2026-08-14

  IWP-2 is a potent Wnt production inhibitor for dissecting Porcupine-dependent signaling in cancer models. This guide combines mechanistic pharmacology with single-nucleus study design to improve assay interpretation, controls, and translational restraint.

• PPP1R3G/PP1γ Control RIPK1 Cell Death

  2026-08-14

  The reference study identifies PPP1R3G as a regulatory factor that recruits PP1γ to TNFR1 complex I, removes inhibitory RIPK1 phosphorylation, and enables RIPK1-dependent apoptosis and type I necroptosis. Its combination of CRISPR screening, genetic rescue, phosphosite analysis, and mouse experiments provides a mechanistic framework for interpreting how RIPK1 kinase activation is controlled in inflammatory cell death.

• EDC.HCl: Practical Coupling Workflow

  2026-08-13

  EDC.HCl is a water-soluble carbodiimide used to activate carboxyl groups for amide bond formation in peptide synthesis, bioconjugation, and related in vitro workflows. It should be handled as a laboratory reagent only; no in vivo or clinical data are available, and long-term storage of prepared solutions is not recommended.

• ACE2 Libraries Map SARS-CoV-2 Variant Receptor Usage

  2026-08-13

  Shukla et al. developed a barcode-based pseudotyped-virus assay that simultaneously measures entry through multiplexed ACE2 orthologs and human receptor mutants. The study shows that SARS-CoV-2 spike evolution produces relatively modest changes in human ACE2 usage but substantially reshapes compatibility with animal ACE2 sequences, providing a scalable framework for studying viral adaptation and cross-species transmission.

• AMPK, Mitophagy, and Inflammation in Diabetic Periodontium

  2026-08-12

  A 2026 FASEB Journal study identifies AMPK as an upstream regulator linking PINK1/Parkin-mediated mitophagy with NLRP3-associated inflammation in mechanically loaded periodontal tissue. Its combined in vitro and in vivo design suggests that restoring mitochondrial quality control may be especially relevant when mechanical stress occurs in a high-glucose environment.

• EDTA-Free Protease Inhibitor Cocktail for OXPHOS

  2026-08-12

  The Protease Inhibitor Cocktail is an EDTA-Free Protease Inhibitor formulation supplied as a 100X DMSO stock for protecting proteins during cell and tissue extraction. Its broad-spectrum composition supports intact lysates for Western blotting, co-immunoprecipitation, pull-down, imaging, and kinase workflows, while OXPHOS studies require separate validation of biological effects.

• LRPPRC–Dasatinib Synergy in OXPHOS Cancer

  2026-08-11

  The reference study identifies dasatinib as a synergistic partner for LRPPRC inhibition and proposes a dual-genome mechanism for disrupting tumor-cell oxidative phosphorylation. Its findings connect mitochondrial transcript destabilization with suppression of nuclear-encoded OXPHOS programs, while also highlighting the need for biomarker-guided validation beyond cell models.

• MEDUSA Reveals Hidden Drug-Death Mechanisms

  2026-08-11

  Honeywell et al. introduce MEDUSA, a time-resolved modeling framework that separates growth and death in pooled functional genomic screens. Its application to DNA damage responses shows that p53 loss can redirect cells from apoptosis toward a respiration-dependent nonapoptotic death state, improving mechanistic interpretation for cancer research.

• KU-55933: ATM Signaling in Cancer Research

  2026-08-10

  KU-55933 is a selective ATM kinase inhibitor for dissecting DNA damage signaling, Akt regulation, and cell-cycle control. This guide connects ATM inhibition with mitochondrial stress research and provides an assay-focused framework for interpreting cancer cell responses.

• E-64 for Cathepsin S and Protease Assays

  2026-08-09

  E-64 provides a practical route to irreversible cysteine protease inhibition in purified-enzyme, lysate, and mechanistic cancer research workflows. Its broad activity is especially useful for active-site titration and pathway perturbation, while careful controls are essential when interpreting cathepsin S biology.

• Phosphotungstic Acid Negative Stain Workflow

  2026-08-08

  Use a ready-to-use negative stain to move from purified macromolecule screening to virus imaging, bacteria visualization, and glycoprotein morphology checks with a controlled, repeatable grid workflow. The guide emphasizes practical parameter ranges, comparative assay design, and troubleshooting limits when structural contrast is used to support—but not replace—glycan-binding or antiviral experiments.
