Luminol-based Assay for Detection of Immunity Elicitor-induced Hydrogen Peroxide Production in Arabidopsis thaliana Leaves [PDF]

, 2015
In Arabidopsis thaliana, one of the very early immune-related responses induced after elicitor perception is the oxidative burst, i.e. reactive oxygen species (ROS) generation including superoxide anion and hydrogen peroxide (H2O2).

Confined electrochemiluminescence in vertically ordered silica mesochannels for the imaging of hydrogen peroxide released from single cells

Electrochemistry Communications, 2019
Here, the confined electrochemiluminescence (ECL) of luminol and hydrogen peroxide is achieved in vertically ordered silica mesochannels (SMCs) and applied to map the efflux of hydrogen peroxide from single living cells. The vertical alignment of SMCs on

The secreted redox sensor roGFP2‐Orp1 reveals oxidative dynamics in the plant apoplast

Plant Biology, Volume 28, Issue 2, Page 359-373, March 2026.
Using the secreted redox biosensor roGFP2‐Orp1, we reveal differences in extracellular (apoplastic) oxidative processes between and within species, depending on cell type and immune signalling. Abstract Specific generation of reactive oxygen species (ROS) is important for signalling and defence in many organisms. In plants, different types of ROS serve

Lactoferrin treatment activates acetylcholinesterase, decreasing acetylcholine levels in non‐small cell lung cancer (NSCLC) cell culture supernatants, inhibiting cell survival

FEBS Open Bio, Volume 16, Issue 2, Page 412-431, February 2026.
Representation of the suggested mode of action of lactoferrin (Lf) in nonsmall cell lung cancer (NSCLC) A549 cells. Lf induces activation of caspase‐3 by activating p53 and AChE leading to decreased ACh concentrations. In turn, ACh signaling leads to activation of VEGF and AKT and blocking of caspase‐3.

A Comparison between Four Analytical Methods for the Measurement of Fe(II) at Nanomolar Concentrations in Coastal Seawater

Frontiers in Marine Science, 2017
Dissolved Fe(II) in seawater is deemed an important micronutrient for microbial organisms, but its analysis is challenging due to its transient nature. We conducted a series of Fe(II) method comparison experiments, where spikes of 5 to 31 nM Fe(II) were ...

Smart REASSURED Sensors via Machine‐Augmented Printable On‐Paper Arrays

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
This perspective highlights the emerging role of pattern‐recognition, printable on‐paper sensor arrays for intelligent PoC diagnostics. It discusses how paper's inherent limitations can be overcome through surface modification and scalable printing, and how machine‐learning analysis of cross‐reactive arrays enables multiplexed, low‐cost, and REASSURED ...

Elucidation of Proteoforms of Chinese Hamster Ovary (CHO) Phospholipase B‐Like 2 (PLBL2) Captured From a Monoclonal Antibody

Biotechnology and Bioengineering, Volume 123, Issue 2, Page 406-419, February 2026.
A platform approach to the affinity capture and enrichment of host cell proteins to enable their subsequent deep characterization and elucidation of variants or proteoforms (e.g., molecular size variants, charge variants, glycoforms, etc.). ABSTRACT Removing host cell proteins (HCPs) during biotherapeutic manufacturing is essential to ensure patient ...
