• DiI (DiIC18(3)) Membrane Probe Guide

  2026-08-29

  DiI (DiIC18(3)) provides orange-red labeling of plasma membranes in live or fixed cells and tissues, supporting membrane visualization, neuronal tracing, migration, fusion, adhesion, and lipoprotein workflows. Because it is insoluble in water and membrane localization can be affected by permeabilization, it should not be used as an aqueous-only stain or as an exclusive intracellular organelle marker.

• Angiotensin Peptides and SARS-CoV-2 Spike Binding

  2026-08-26

  Oliveira et al. report that naturally occurring angiotensin peptides can enhance SARS-CoV-2 spike-protein binding to host receptors, with particularly strong effects observed for selected shortened or N-terminally modified fragments. The study introduces a biochemical link between renin–angiotensin system peptides and viral receptor engagement, while also defining important limits for interpreting binding results in cardiovascular, renal, and infection models.

  Build customizable fluorescent RNA probes for in situ hybridization and Northern blotting with a T7-driven workflow that balances probe yield against Cy3 signal. This guide connects practical labeling decisions with transcript-localization questions raised by recent RNAi delivery research.

• Amplex Red for Sensitive H2O2 Assays

  2026-08-23

  Amplex Red converts otherwise invisible hydrogen peroxide and peroxidase activity into a quantitative resorufin signal for cell, biochemical, and microsensor workflows. This guide combines practical assay design with lessons from a nanoelectrode study that measured active immobilized HRP at femtogram sensitivity.

• Tricine-SDS-PAGE Gel Preparation Kit Guide

  2026-08-22

  The Tricine-SDS-PAGE Electrophoresis System Gel Preparation Kit is intended for resolving low-molecular-weight proteins and peptides that are difficult to separate with conventional Tris-SDS-PAGE. It supports research workflows using denaturing or non-denaturing electrophoresis, but it is not intended for diagnostic, clinical, or medical use.

• Salvianolic Acid B: From Collagen to Matrix State

  2026-08-22

  Salvianolic acid B is a mechanistically informative natural product for fibrosis studies. This article explains how to design assays that distinguish collagen abundance from LH2-dependent matrix remodeling and interpret antifibrotic activity with greater causal precision.
