An Immunological Approach to Gibberellin Purification and Quantification

Abstract
Gibberellin (GA) specific, high-affinity monoclonal antibodies have been used to assay the GA content of various plant [Pisum sativum and Marah macrocarpus] tissues and to purify selected GAs by immunoaffinity chromatography. These immunological techniques may not stand alone as a general method of GA analysis. The results of this study indicate, however, that in conjunction with gas chromatography-mass spectrometry for positive GA identification, radioimmunoassay and immunoaffinity chromatography are extremely powerful tools for purifying and quantifying GAs from plant tissues.
