  The present invention provides a novel reporter gene assay. In particular, the present invention provides a histochemical reporter gene assay employing α- L -arabinofuranosidase in combination with a chromogenic α- L -arabinofuranosidase substrate. The α- L -arabinofuranosidase histochemical reporter assay may be utilized to characterize gene regulatory regions of interest either alone or in combination with other assays.
