AP conjugated mouse IgG (H+L) cross-adsorbed secondary antibody in western blotting

Alkaline phosphatase (AP)-conjugated secondary antibodies are commonly used in enzyme driven applications, such as western blotting, ELISA, immuno-histochemistry, and others. AP-conjugated secondary antibodies use alkaline phosphatase substrates mainly for chemiluminescent or colorimetric detection. Navigate this page to find our menu of AP-conjugated secondary antibodies along with recommended substrates for your western blotting, ELISA, or immuno-histochemistry experiments.

Fluorescent substrates for signal amplification of AP conjugates

Endogenous phosphatase activity in zebra brain visualized with ELF Endogenous Phosphatase Kit

(Cat. No. E6601).

ELF signal amplification is based on ELF 97 phosphate, a substrate for both alkaline phosphatase and acid phosphatase. Upon cleavage this substrate yields a bright yellow-green fluorescence with excellent photostability. The ELF 97 signal is more photostable than signals achieved using either direct or indirect detection with fluorescein conjugates. ELF 97 is well suited for immunolabeling and can be detected with imaging instrumentation that is equipped with a UV light excitation source.
