A nonradioactive labelling and detection method for plant genomic DNA analysis is compared to the radioactive method. The radioisotopes are replaced by a nucleotide, digoxigenin-11-dUTP, and the signal detection is accomplished by the enzymatic reaction of alkaline phosphatase, conjugated to anti-digoxigenin antibodies, with the chemiluminescent substrate AMPPD (3-(2′-spiroadamantane)-4-methoxy-4(3″ phosphorytoxy) phenyl-1, 2-dioxetane). The sensitivity of the radioactive and nonradioactive methods are directly compared using identical Southern blots subjected to the radioactive and nonradioactive detection. The advantages of this nonradioactive method are discussed.
