Compounds I of Catalase and Horse Radish Peroxidase: π-Cation Radicals [PDF]

open access: yesProceedings of the National Academy of Sciences, 1971
Two-electron oxidation of cobaltous octaethylporphyrin [Co(II)(Et) 8 P] yields a stable π-cation radical [Co(III)(Et) 8 P] 2+. , the optical spectrum of which exhibits spectral changes dependent upon the nature of the counterion.

Eco-Friendly Fluorescent ELISA Based on Bifunctional Phage for Ultrasensitive Detection of Ochratoxin A in Corn

open access: yesFoods, 2021
Conventional enzyme-linked immunosorbent assay (ELISA) is commonly used for Ochratoxin A (OTA) screening, but it is limited by low sensitivity and harmful competing antigens of enzyme-OTA conjugates.

Integrated immunoassay-based broad detection of multi-class mycotoxins

open access: yesFood and Agricultural Immunology, 2018
Europium (Eu3+) and horse radish peroxidase (HRP) are highly promising biosensors due to its excellent physical and chemical properties. The two biosensors are widely applied in time-resolved fluoroimmunoassay (TRFIA) and chemiluminescence enzyme-linked ...

Plasmon-Enhanced Enzymatic Reactions: A Study of Nanoparticle-Enzyme Distanceand Nanoparticle Loading-Dependent Enzymatic Activity

open access: yesNano Biomedicine and Engineering, 2011
A detailed investigation of the dependence of the efficiency of plasmon-enhanced enzymatic reactions on the distance between silver island films (SIFs) and horse radish peroxidase (HRP) enzyme and on the loading of SIFs on glass surfaces is presented ...

Preparation of the luciferase-labeled antibody for improving the detection sensitivity of viral antigen

open access: yesVirology Journal, 2022
Background Viral antigen detection test is the most common method used to detect viruses in the field rapidly. However, due to the low sensitivity, it can only be used as an auxiliary diagnosis method for virus infection. Improving sensitivity is crucial

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

open access: yesMolecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Immobilization of horse radish peroxidase on different macroporous glycydil methacrylates for wastewater treatment [PDF]

open access: yes, 2011
Removal of phenolic compounds from wastewaters has been investigated by many researchers and it has been shown that horse radish peroxidase can react with aqueous phenolic compound in the presence of hydrogen peroxide and form non-soluble materials that ...

Effect of Physical Factors on Reactions of Horse-Radish Peroxidase Complexes with Reduced Cytochrome c

open access: yes, 1963
This investigation concerns the effect of certain physical factors—viscosity, dielectric constant, ionic strength, and temperature of the medium—on the reaction of hydrogen peroxide and ferrocytochrome c in the presence of the enzyme horse-radish ...

Oppositely Charged Single Enzyme Nanogels Form Versatile Coacervates for Efficient Enzyme Cascade Catalysis

open access: yesAdvanced Materials, EarlyView.
Oppositely charged single enzyme nanogels (SENs) phase‐separate into bi‐enzymatic coacervate microdroplets, acting as both scaffold and functional units. By tuning SEN ratios, these coacervates create specific microenvironments that enable selective small‐molecule enrichment and efficient intermediate diffusion.
