• Recombinant Human FGF-19: Practical Assay Guide

  2026-09-29

  This guide explains how to reconstitute, qualify, and apply Recombinant Human FGF-19 in FGFR4 binding, cell proliferation, and metabolic regulation research. It is appropriate for controlled in vitro workflows, but the dossier-based activity data should not be interpreted as evidence of clinical efficacy, therapeutic performance, or universal activity across cell types.

• Potato Virus X for RNA Gene Delivery

  2026-09-28

  The reference study develops potato virus X coat protein as a programmable nucleoprotein platform for delivering custom mRNA and circular RNA. Its central advance is the demonstration of self-assembled, length-controlled, and mixed-composition particles that transfect eukaryotic cells and support reporter-protein expression, while also defining important questions for future validation.

• Z-VAD-FMK for Apoptosis and Host-Cell Assays

  2026-09-28

  Use Z-VAD-FMK to test whether a phenotype depends on caspase signaling—not as a stand-alone proof of apoptosis or cell survival. This guide turns that distinction into a practical workflow for immune-cell and host–pathogen studies, including experiments inspired by recent Toxoplasma virulence research.

• Annexin V-PE in Inflammatory Cell-Fate Studies

  2026-09-27

  The Annexin V-PE Apoptosis Detection Kit can add a cell-fate readout to studies of inflammatory signaling. This article explains how to interpret phosphatidylserine staining alongside the monocyte findings in preterm-infant sepsis research—and where the assay’s limits matter.

• Cy3 Goat Anti-Mouse IgG (H+L) Antibody Guide

  2026-09-26

  This Cy3-conjugated secondary antibody detects mouse primary antibodies in immunofluorescence, flow cytometry, and fluorescent western blot workflows. It is intended for research use only—not diagnostic or medical use—and should not be assumed suitable for live-cell functional assays without checking the sodium azide-containing formulation.

• Danazol Workflows for HPG-Axis Research

  2026-09-25

  Use Danazol to build mechanistically informed endocrine assays—from LH-stimulated steroidogenesis measurements to carefully controlled puberty-model studies. A recent rat study also offers a useful framework for testing interventions against Danazol- and diet-associated HPG-axis changes, while highlighting why model-specific controls matter.

• EdU Imaging Kits for RCC Proliferation Studies

  2026-09-25

  Track S-phase entry while testing how gingerenone A and sunitinib affect renal cancer cells. EdU imaging adds a direct DNA-synthesis readout alongside metabolic and viability assays, helping distinguish reduced proliferation from changes in glycolysis alone.

• FH1 Small Molecule for iHep Maturation

  2026-09-24

  FH1 supports iPS-derived hepatocyte-like cell maturation, with reported gains in albumin secretion and CYP3A4 alongside reduced AFP. This practical guide shows how to build a controlled FH1 workflow, interpret multiple maturity readouts, and keep emerging gene-control applications within the evidence.

• 5-Aminolevulinic acid HCl: Assay Guide

  2026-09-24

  A scenario-based guide to using 5-Aminolevulinic acid HCl (SKU B2070) in cell-based and heme-pathway research, with practical controls for viability, proliferation, and photodynamic workflows. It distinguishes product specifications from study-specific findings and explains how to interpret results without overextending the evidence.

• Exercise Limitation Before Muscle Dysfunction in PH

  2026-09-23

  In two rat models of pulmonary hypertension, reduced exercise capacity was evident alongside right ventricular dysfunction before intrinsic skeletal muscle functional deficits were detected. The comparison across strains and disease severity suggests that cardiopulmonary impairment can limit exercise early, while muscle atrophy may emerge in more severe disease.

• Angiotensin Peptides and SARS-CoV-2 Spike Binding

  2026-09-23

  Oliveira et al. show that naturally occurring angiotensin fragments can modify SARS-CoV-2 spike-protein binding to host receptors, with the strongest effects observed for AXL and selected N-terminally truncated peptides. The study provides a mechanistic bridge between renin-angiotensin signaling and viral-entry biology, while its cell-free binding design requires careful interpretation before translation to infection or clinical studies.

• Coumestrol Workflows for ER and Ferroptosis Studies

  2026-09-22

  Coumestrol combines nanomolar estrogen-receptor pharmacology with a distinct high-micromolar ferroptosis workflow in rheumatoid arthritis fibroblast-like synoviocytes. This guide translates the reference study into practical dosing, orthogonal assays, troubleshooting steps, and controls for nuclear receptor and inflammation research.

• RESTRICT-seq Maps Epigenetic Dependencies in SCC Resistance

  2026-09-22

  The RESTRICT-seq preprint introduces a time-gated CRISPR screening strategy for separating gene perturbation from later selection for squamous cell carcinoma resistance. Its findings identify epigenetic regulators that may sustain resistant states and provide a framework for connecting genetic screens with chemically testable vulnerabilities.

• Berberine Hydrochloride: Mechanisms & Bone Research

  2026-09-21

  Berberine hydrochloride is an isoquinoline alkaloid used in metabolic, antimicrobial, apoptosis, ferroptosis, and gut–bone research. Recent preclinical evidence links berberine-driven butyrate production and GPR41-associated tuft cell expansion with improved intestinal barrier and bone-immune homeostasis during estrogen deficiency.

• 7-dehydro Cholesterol: Applied Research Workflows

  2026-09-21

  7-dehydro Cholesterol connects DHCR7-dependent sterol flux with UVB-driven vitamin D3 formation, oxidation-sensitive lipid biology, and disease-model research. This practical guide shows how to build controlled workflows, interpret chemical versus genetic perturbations, and troubleshoot solubility, photoconversion, and phenotype variability.
