New fluorimetric assay of horseradish peroxidase using sesamol as substrate and its application to EIA

open access: yesJournal of Pharmaceutical Analysis, 2012
Horseradish peroxidase (HRP) is generally used as a label enzyme in enzyme immunoassay (EIA). The procedure used for HRP detection in EIA is critical for sensitivity and precision.

RF Sensor with Graphene Film for HRP Concentration Detection

open access: yesC, 2023
This paper presents a radio-frequency (RF) antenna as a sensor to detect Horseradish peroxidase (HRP). At the core of the proposed approach is a graphene film deposited on a stub connected to an RF antenna. The graphene film is doctor bladed on the stub.

Conjugation of Antibodies to Horseradish Peroxidase [PDF]

open access: yesCold Spring Harbor Protocols, 2019
Antibodies conjugated with horseradish peroxidase (HRP) are one of the most widely used bioreagents in the biological sciences. This protocol is a basic method for adding HRP to a thiolated antibody and can be adapted for use with different cross-linkers. Conjugation methods usually focus on linking through the lysines on HRP because there are only six

Direct Electrochemistry of Horseradish Peroxidase-Gold Nanoparticles Conjugate

open access: yesSensors, 2009
We have studied the direct electrochemistry of horseradish peroxidase (HRP) coupled to gold nanoparticles (AuNP) using electrochemical techniques, which provide some insight in the application of biosensors as tools for diagnostics because HRP is widely ...

Horseradish peroxidase ototoxicity [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1976
Following intracochlear perfusion of horseradish peroxidase (HRP) in artifical perilymph (1% for 10 min–4 h; 1–24 survival), HRP was demonstrated histochemically in some hair cells and supporting cells, the basilar membrane, spiral limbus and stria vascularis of 18 anesthetized (DIAL) guinea pigs. No neuronal retrograde transport occurred.
