• Withania somnifera Digestion: LC–MS/MS Findings

  2026-08-17

  A 2026 study combined simulated gastrointestinal digestion with LC–MS/MS, molecular networking, and untargeted metabolomics to track chemical changes in Withania somnifera leaf and root extracts. Withaferin A and withanoside IV were transformation-prone, whereas withanolide A was comparatively stable, demonstrating why botanical bioavailability studies must evaluate digestive stability before downstream pharmacokinetic testing.

• Cell Counting Kit-8 Plus for ccRCC Assays

  2026-08-16

  Cell Counting Kit-8 Plus delivers a rapid WST-8 readout for separating growth inhibition from metabolic effects in clear cell renal cell carcinoma models.

• SPRTN Ubiquitin Binding and DPC Proteolysis

  2026-08-15

  The reference preprint identifies a ubiquitin-binding domain within the N-terminal catalytic region of SPRTN and links ubiquitin-chain recognition to selective DNA–protein crosslink proteolysis. Its central implication is that DPC ubiquitination is not merely a downstream processing mark but a direct substrate-specificity signal that can strongly accelerate SPRTN activity.

• Partial BACE Inhibition Preserves Synaptic Function

  2026-08-14

  Satir et al. show that moderate inhibition of β-secretase (BACE) can reduce amyloid-β secretion without impairing synaptic transmission in cultured rat cortical neurons. The study separates potentially protective partial target engagement from higher-level inhibition associated with synaptic dysfunction, offering a useful framework for interpreting BACE inhibitor exposure in Alzheimer’s disease research.

• Pentoxifylline Workflows for Inflammation Research

  2026-08-13

  Build reproducible cAMP-centered inflammation assays with Pentoxifylline, then extend the workflow to delivery-focused psoriasis models. The practical framework connects concentration screening, cytokine readouts, and dual-drug niosome optimization while separating evidence-backed parameters from laboratory starting points.

• D-N-Acetylgalactosamine Protocol Guide

  2026-08-13

  D-N-Acetylgalactosamine (SKU B7904) provides a high-purity, water-soluble reagent for examining glycoprotein constituents and glycosylation-related workflows in neurological research. It is suitable for aqueous or compatible DMSO preparations, but not for ethanol-based protocols or long-term storage of prepared solutions.

• Targeted mRNA Nanoparticles Repair the Poststroke BBB

  2026-08-12

  Gao and colleagues developed mannose-targeted lipid nanoparticles carrying mRNA encoding interleukin-10 to redirect microglial responses after ischemic stroke. In mouse models, this strategy reduced neuroinflammation, improved blood–brain barrier integrity, limited neuronal apoptosis, and alleviated neurological deficits, while suggesting a therapeutic window extending to at least 72 hours after stroke.

• Substance P: NK-1 Signaling and Research Use

  2026-08-12

  Substance P is a tachykinin neuropeptide that activates neurokinin-1 receptors and supports research on pain transmission, inflammation, and immune signaling. B6620 is a research-grade lyophilized peptide with defined identity, solubility, purity, and storage specifications.

• Tubastatin A: A Practical Guide to HDAC6 Assays

  2026-08-11

  Tubastatin A is a selective HDAC6 inhibitor whose value extends beyond target engagement. This guide explains how to connect α-tubulin acetylation with pyroptosis, necroptosis, myocardial injury, and better translational assay design.

• Antiarrhythmic Drugs and KCa2 Channels in AF

  2026-08-11

  The reference study systematically tested ten antiarrhythmic drugs against human KCa2.2 and KCa2.3 channels using automated whole-cell patch clamp. Only dofetilide and propafenone produced measurable inhibition, and their concentrations for channel block were substantially above free therapeutic plasma concentrations, arguing against clinically important KCa2 modulation as a general mechanism of atrial fibrillation therapy.

• Dorsomorphin 2HCl: AMPK Workflow Guide

  2026-08-10

  Dorsomorphin 2HCl enables causal testing of AMPK-dependent metabolism while also supporting BMP, osteogenesis, and hepcidin studies. This workflow-focused guide covers formulation, pathway controls, assay selection, and troubleshooting for cell and preclinical models.
