• Cyclosporin Variants and Mitochondrial Pore Activity

  2026-09-01

  The reference study combines NMR spectroscopy, molecular dynamics, and mitochondrial swelling assays to explain why closely related cyclosporin congeners differ in mitochondrial pore inhibition. Its key practical implication is that backbone flexibility may help determine membrane-associated activity, but mitochondrial effects should not be treated as a direct surrogate for calcineurin-dependent immunosuppression.

• Sulfo-NHS-SS-Biotin: Reliable Cell-Surface Assays

  2026-08-31

  This scenario-based guide explains how Sulfo-NHS-SS-Biotin, SKU A8005, can complement cell viability, proliferation, and cytotoxicity assays by enabling cleavable labeling of cell-surface proteins. It provides practical guidance on experimental design, fresh reagent preparation, data interpretation, and vendor selection.

• Biotin-tyramide for TSA Imaging Workflows

  2026-08-31

  Biotin-tyramide converts HRP activity into a localized biotin map for sensitive IHC, ISH, and spatial validation experiments. This guide connects practical TSA assay design with chemoproteomic thinking, emphasizing controls, fresh reagent preparation, and troubleshooting for high-resolution detection.

• Bifidobacterium, FMT, and PET in Chronic HE

  2026-08-30

  This 2025 European Journal of Neuroscience study used [18F]PBR146 micro-PET/CT to compare Bifidobacterium and fecal microbiota transplantation in bile duct ligation rats with chronic hepatic encephalopathy. Although global brain uptake, behavior, and measured cytokines were not significantly different, regional imaging and microbiome profiles suggested that Bifidobacterium may attenuate neuroinflammation more effectively than FMT.

• Trichostatin A (TSA) Workflows for HDAC Research

  2026-08-29

  Trichostatin A (TSA) provides a practical way to connect HDAC activity with chromatin remodeling, cancer phenotypes, differentiation, and cytoskeletal behavior. This workflow-focused guide explains dosing, controls, assay selection, and how to interpret TSA alongside the emerging HDAC6–tubulin lactylation pathway.

• AMPK–SQSTM1 Feedback Under Metabolic Stress

  2026-08-28

  The reference study identifies a double-positive feedback loop between AMPK and SQSTM1/p62 that jointly activates AMPK and NFE2L2/NRF2 during metabolic stress. Its mechanistic findings connect lysosomal pH, ROS, TAK1, TFEB/TFE3, and KEAP1 degradation, providing a framework for understanding stress adaptation in STK11/LKB1- and KEAP1-altered lung cancer.

• TCF25 Links Glucose Starvation to Lysosomal Cell Death

  2026-08-28

  Ren et al. identify TCF25 as a nutrient-responsive regulator that increases V-ATPase-dependent lysosomal acidification during glucose starvation. The study shows that this response is initially adaptive, supporting autophagy and ATP production, but prolonged activation promotes ferritinophagy, lysosomal membrane permeability, and lysosome-dependent cell death, with implications for hepatic ischemia-reperfusion injury.

• Bazedoxifene Antimalarial Activity and Hemozoin Inhibition

  2026-08-27

  Sudhakar and colleagues show that selective estrogen receptor modulators can be repurposed as antimalarial candidates, with bazedoxifene producing the strongest activity against Plasmodium falciparum and reducing Plasmodium berghei infection in female mice. The study links this effect to impaired hemozoin formation, while also revealing that host sex can influence in vivo efficacy and should be considered in translational drug-repurposing studies.

• ABT-888 (Veliparib): PARP1/2 Research Guide

  2026-08-27

  ABT-888, also called Veliparib, is a selective PARP1/PARP2 inhibitor used to study DNA repair inhibition and chemotherapy sensitization. Its preclinical activity depends on the damaging agent, tumor model, and DNA damage-response context, so it should be interpreted as a research tool rather than a universal sensitizer.

• AO/PI Staining Solution for Viability Workflows

  2026-08-26

  Build a more reliable fluorescent cell viability assay by separating intact from membrane-compromised cells while reducing debris and red blood cell interference. This practical guide translates findings from diabetic nephropathy research into reproducible AO/PI workflows, controls, and troubleshooting decisions.

• SmD2 Acetylation Rewires HCC Splicing and PARP Response

  2026-08-26

  A 2024 Nature Communications study identifies SmD2 as an acetylation-sensitive core spliceosome component that links alternative splicing, DNA-damage repair, and PARP inhibitor response in hepatocellular carcinoma. The work supports a combination strategy involving HDAC inhibition and PARP blockade, while also defining important requirements for validating this mechanism in independent tumor models.

• Bafilomycin A1: Reliable V-ATPase Assays

  2026-08-25

  Learn how Bafilomycin A1 (SKU A8627) can improve experimental control in intracellular pH regulation, lysosomal function research, and cell viability workflows. This scenario-based guide combines product handling data with published evidence to support reproducible interpretation and practical vendor selection.

• Sodium Salicylate and the Next PDAC Translation

  2026-08-25

  A translational perspective on using sodium salicylate as a mechanistic NF-κB inhibitor alongside stromal-remodeling strategies in pancreatic cancer research, with clear boundaries between established evidence and testable hypotheses.

• Metoprolol Tartrate: Selective β1 Blockade

  2026-08-24

  Metoprolol Tartrate is a β1-adrenergic blocking agent for controlled cardiovascular research and receptor-selectivity studies. Comparative transplantation evidence indicates that β1-selective inhibition does not reproduce the delayed engraftment observed with nonselective β-blockade.

• n-Dodecyl-β-D-maltoside for WecA Assays

  2026-08-24

  Discover how n-Dodecyl-β-D-maltoside, or DDM, can be treated as an assay-design variable rather than merely a purification additive. This guide connects membrane-protein chemistry with WecA activity measurements, controls, and practical optimization decisions.
