[A simplified method of determination of cAMP in plants using modified enzyme immunoassay].

A modification of enzyme immunoassay for quantification of cAMP and its derivatives in plants is suggested, which is based on the use of cAMP-specific primary rabbit antibodies and secondary goat antibodies conjugated with peroxidase. The lower threshold of this method is 10 pM. This technique is highly specific, simple, and inexpensive.
