Description

Application

4-Aminophthalhydrazide has been used in:

• chemiluminescence-based reactive oxygen species (ROS) assay in bone marrow (BM) neutrophils post-Yersinia pseudotuberculosis infection
• neutrophil ROS assays post-K. pneumonia exposure
• neutrophil ROS assays in response to formylated-methionine-leucine-proline

Biochem/physiol Actions

4-Aminophthalhydrazide or isoluminol is a chemiluminescent compound that comprises a phthalazine ring. It is more hydrophilic than luminol. Isoluminol is commercially used in a wide variety of in vitro immunoassays and is a chemiluminescence amplifier for studying reactive oxygen species. It is also useful as an electroluminescence (ECL) biosensor and as a probe for rapid microbial detection.

Features and Benefits

Produces chemiluminescence.
