Description

Specificity

4-Chloro-1-Naphthol is a peroxidase substrate suitable for use in immunoblotting procedures. This substrate produces an insoluble end product that is blue in color and can be observed visually.

Application

4-Chloro-1-naphthol has been used as a substrate in enzyme-linked immunospot (ELISpot) assay for detection of the spots. It has also been used as a precipitating chromogenic substrate for visualizing the antigen−antibody-reactive bands following western blotting.

Quantity

Contains 30 mg substrate per tablet.

Reconstitution

Dissolve 1 tablet in 10 ml of methanol. Add 2 ml of methanol stock solution to 10 ml of triethanolamine buffered saline, pH 7.5. Add 5 μl of fresh 30% hydrogen peroxide (Sigma Product No. H-1009) immediately prior to use.
