  2026-09-29

  Protect Wnt receptor-complex samples from rapid proteolysis without introducing EDTA that can disrupt divalent-cation-sensitive assays. This workflow shows how an EDTA-free 100X DMSO formulation supports lysate preparation, co-immunoprecipitation, phosphorylation analysis, and kinase assay development.

• Protease Inhibitor Cocktail for Signaling Assays

  2026-09-28

  Learn how a Protease Inhibitor Cocktail improves protein degradation prevention and strengthens interpretation of bioenergetic, ER-stress, Western blot, and co-immunoprecipitation assays. This article translates findings from a ciclopirox NSCLC study into practical sample-preservation decisions.

• SARS-CoV-2 Variant Shifts in ACE2 Receptor Use

  2026-09-28

  Shukla and colleagues developed a barcoded pseudovirus assay to compare how six SARS-CoV-2 spike proteins use a multiplexed library of 30 ACE2 sequences. Their results show that variant-associated changes have modest effects on human ACE2 compatibility but can substantially alter compatibility with animal orthologs, highlighting the value of testing host and viral sequence variation together.

• AZ505: A Selective SMYD2 Inhibitor for Research

  2026-09-27

  AZ505 is a substrate-competitive SMYD2 inhibitor that blocks access to the enzyme’s peptide-substrate groove without competing with SAM. Product information reports biochemical potency and selectivity, while a cisplatin-induced kidney disease study provides preclinical evidence that pharmacological SMYD2 inhibition can reduce renal fibrosis and inflammation.

• PFHxS Disrupts Zebrafish Lipid Homeostasis via PPARα

  2026-09-26

  An integrated lipidomic and transcriptomic study found that environmentally relevant PFHxS exposures altered multiple lipid classes and PPAR-related pathways in zebrafish larvae. Molecular simulation and antagonist coexposure support PPARα as a potential initiating target, while the evidence does not establish it as the sole cause of the observed lipid changes.

• Sodium Oxamate: Reliable Assay Design

  2026-09-25

  Learn how Sodium Oxamate (SKU C3893) can help investigate LDH-A-dependent metabolism without mistaking metabolic readout changes for altered cell number. This scenario-driven guide covers assay compatibility, dose-finding, interpretation, and practical product-selection criteria.

• Mycobacterium tuberculosis WecA: Expression and Kinetics

  2026-09-25

  The study establishes a practical route to produce and analyze the challenging membrane enzyme WecA, using regulated expression in Escherichia coli, affinity purification, mass-spectrometric identification, and UMP-based activity detection. Its kinetic analysis identifies tunicamycin as a competitive inhibitor and provides an experimental foundation for WecA mechanism studies and inhibitor discovery, while leaving important questions about assay conditions and inhibitor behavior for further work.

• Wnt3a Dimer Organizes the Extracellular Signalosome

  2026-09-24

  Cryo-EM structures show how a Wnt3a homodimer organizes Frizzled and LRP6 into a 2:4:2 extracellular complex, while interface mutations connect dimer formation to receptor clustering and downstream signaling. The findings provide a structural framework for understanding canonical Wnt activation and for investigating the Wnt–LRP6 interface.

• CD80 and 4-1BBL mRNA T-Cell Vaccine Findings

  2026-09-24

  Cho et al. reported that expanded CD4 T cells expressing both CD80 and 4-1BBL produced stronger CD8 T-cell responses than cells expressing either ligand alone, with antitumor activity in mouse tumor models. The poster supports a cellular-vaccine strategy worth testing further, while its limited methodological detail and preclinical scope constrain translation.

• UBE2F–SAG Neddylation Activates RHEB in Liver Tumors

  2026-09-24

  The study identifies RHEB as a non-cullin substrate of the UBE2F–SAG neddylation machinery and links modification at K169 to stronger mTORC1 signaling. Cell and liver-model findings connect this mechanism to steatosis and tumorigenesis following Pten loss, while patient data show an association between UBE2F, mTORC1 activity, and hepatocellular carcinoma survival.

• TMRE mitochondrial membrane potential assay kit Guide

  2026-09-23

  Use TMRE to convert mitochondrial polarization into a quantitative red-fluorescence readout for apoptosis, necrosis, and energy-stress studies. This workflow emphasizes CCCP validation, sodium-driven mitochondrial disruption, scalable plate formats, and troubleshooting that separates true depolarization from handling artifacts.

• Human iPSC Sensory Neurons for HSV-1 Latency

  2026-09-22

  Oh et al. developed a scalable human iPSC-derived sensory neuron system that supports HSV-1 latency and stimulus-induced reactivation. The model combines neuronal functional validation with virological, transcriptional, and chromatin-based criteria, providing a human-relevant platform for studying latency mechanisms and candidate interventions.

• Bradford Protein Assay Kit: Practical Guide

  2026-09-22

  The Bradford Protein Assay Kit provides a rapid protein quantification assay for soluble samples when limited volume, fast turnaround, and routine concentration measurement are priorities. It is best used with compatible aqueous matrices and should be validated or replaced for detergent-rich, strongly colored, turbid, compositionally unusual, or out-of-range samples.

• HRP Goat Anti-Mouse IgG (H+L): K1221 Guide
