Redox balance and carbonylated proteins in limb and heart muscles of cachectic rats.
- J. Marín-Corral, Cibely C Fontes, +6 authors E. Barreiro
- Chemistry, Medicine
- Antioxidants & redox signaling
- 8 January 2010
In fast- and slow-twitch limb and heart muscles of cachectic rats, redox balance and muscle structure were explored. The nature of the oxidatively modified proteins also was identified in these… Expand
Free and sol-gel immobilized alkaline phosphatase-based biosensor for the determination of pesticides and inorganic compounds
- F. Sánchez, A. Díaz, M. C. R. Peinado, C. Belledone
- Chemistry
- 7 May 2003
Alkaline-phosphatase (ALP) catalyses the hydrolysis of 1-naphthyl phosphate to fluorescent 1-naphthol ( λex = 346 nm, λem = 463 nm). This enzymatic reaction was investigated in presence of… Expand

A polarization fluorescence immunoassay has been developed for the screening of the herbicide dichlorprop [(f)-2-(2,4-dichlorophenoxy)propanoic acid]. The assay is based on the difference in… Expand
Phenol derivatives as enhancers and inhibitors of luminol–H2O2–horseradish peroxidase chemiluminescence
- A. Díaz, F. Sánchez, J. García
- Chemistry
- 1 March 1998
Systematic studies on phenol derivatives facilitates an explanation of the enhancement or inhibition of the luminol‐H2O2‐horseradish peroxidase system chemiluminescence. Factors that govern the… Expand
P-phenol derivatives as enhancers of the chemiluminescent luminol-horseradish peroxidase-H2O2 reaction: substituent effects
- F. Sánchez, A. Díaz, J. García
- Chemistry
- 1 June 1995
Abstract We studied the substituent effects of ten p-phenol derivatives and aniline on the chemiluminescence from the luminol-horseradish peroxidase-H2O2 system. The enhancer effects of some… Expand
Horseradish peroxidase sol-gel immobilized for chemiluminescence measurements of alkaline-phosphatase activity
- A. Díaz, F. Sánchez, J. Ramos, M. C. Torijas
- Chemistry
- 28 February 2002
Naphthyl phosphate is a pro-enhancer of the luminol-H2O2-horseradish peroxidase reaction. Alkaline-phosphatase hydrolyses the phosphate group and produces 2-naphthol. This compound is an enhancer of… Expand
