Fluorescein di-β-D-galactopyranoside (FDG) is one of the most sensitive substrates for galactosidases. Nonfluorescent FDG is sequentially hydrolyzed by β-galactosidase, first to fluorescein monogalactoside (FMG) and then to highly fluorescent fluorescein. Enzyme-mediated hydorlysis of FDG can be followed by the increase in either absorbance or fluorescence.

This concentrated Nitro-Block-II™ Enhancer can be used with CSPD® or CDP-Star® chemiluminescent substrates to increase the alkaline phosphatase signal for protein or nucleic acid blots. The Nitro-Block-II™ membrane enhancer increases chemiluminescent signal intensity on nitrocellulose and PVDF membranes. • Chemically optimized formulations provide enhanced signal intensity in blotting applications with dioxetane-based substrate solutions (CSPD® or CDP-Star® substrates) on nitrocellulose or PVDF membranes. • Enhancer increases signal intensity, allowing decreased signal acquisition time. Increa...

TMB (3,3’, 5,5;-tetramethylbenzidine) chromogen solution may be used as a substrate for horseradish peroxidase (HRP) in ELISAs. Using TMB Use this reagent as supplied, no dilution or further preparation is required. In the presence of peroxidase (HRP, POD), TMB will be converted to a blue color that can be read at OD 650 nm.
Size: 500 ml
TMB (Tetramethyl Benzidine) chromogen solution may be used with horseradish peroxidase (HRP)-based immunodetection procedures.
