• Ibuprofen Workflows for Cell and Cancer Research

  2026-09-01

  Build more reproducible Ibuprofen experiments by connecting solvent handling, dose design, apoptosis induction in colon carcinoma cells, and cell-cycle profiling. This guide also adapts a protein–ligand workflow from a molecular pharmacology study without treating findings from mubritinib as direct evidence for Ibuprofen.

• Fingolimod (FTY720) for Immune-Cell Assays

  2026-08-31

  Fingolimod (FTY720) gives researchers a controllable way to interrogate S1P-dependent lymphocyte trafficking, ERK signaling, and BDNF-associated neurobiology. Used as a mechanistic perturbation rather than an unproven CAR-T component, it can sharpen magnetic T-cell engineering assays and reveal how cell distribution affects efficacy.

• Deep Learning for iPSC-CM Cardiotoxicity Screening

  2026-08-31

  Grafton et al. developed a scalable phenotypic screening strategy that combines induced pluripotent stem cell-derived cardiomyocytes, high-content imaging, and deep learning to detect cardiotoxic patterns. Screening 1,280 bioactive compounds showed that a single deep-learning score could prioritize chemically and mechanistically diverse liabilities, while also revealing the need for orthogonal validation before biological or regulatory decisions.

• Oligo (dT) 25 Beads for mRNA Workflows

  2026-08-30

  Oligo (dT) 25 Beads provide a selective, magnet-assisted route from total RNA or tissue lysate to polyadenylated mRNA for cDNA synthesis, RT-PCR, and sequencing. This guide translates a cisplatin-resistance transcriptomics study into practical capture, QC, assay-design, and troubleshooting decisions.

• Caged Bioluminescent Probe for the Immunoproteasome

  2026-08-29

  Loy and Trader present a protocol for synthesizing and applying a cleavable, bioluminescent activity-based probe selective for the immunoproteasome, particularly the β5i catalytic subunit. The workflow connects peptide-probe chemistry with live-cell and plate-reader assays, while a tissue-mimic experiment suggests a path toward deeper optical studies without establishing in vivo performance.

• Tobramycin: Designing Better Resistance Assays

  2026-08-28

  Tobramycin is an aminoglycoside antibiotic widely used to examine bacterial protein synthesis inhibition and resistance. This article converts historical comparative MIC data into a modern framework for improving assay design, formulation control, and interpretation in microbiology research.

• NSAIDs and Canine Osteosarcoma Cell Viability

  2026-08-28

  Royals and colleagues compared deracoxib and piroxicam in canine osteosarcoma and fibroblast cultures, showing that deracoxib produced concentration-dependent loss of tumor-cell viability at lower concentrations than piroxicam while sparing fibroblasts. The findings support a selective in vitro cytotoxic effect at intermediate or high exposure, but they do not establish activity at typical canine plasma concentrations or demonstrate apoptosis.

• Thapsigargin Workflows for SERCA Pump Inhibition
