ASSAYS OF COUP-TRANSCRIPTION FACTOR INTERACTIONS IN MAMMALIAN SYSTEMS

摘要

Multiple methods for measuring the COUP-TF system, including: a method to measure the level of COUP-TF by combining antibodies with biological samples and measuring the resultant antibody/COUP-TF complex; the binding of COUP-TF to promoters by combining biological samples with COUP-TF binding oligonucleotides and measuring the resultant complex or gene synthesis; and a method to measure COUP-TF inducable promoters by combining native COUP-TF with nuclear extracts of biological samples and measuring the resultant complexes. The methods when applied to human biological samples can detect diabetes due to COUP-TF or promoter defects. In addition to the methods for measuring the COUP-TF system and associated diseases, there are also the polyclonal and monoclonal antibodies necessary for the methods. These bind to at least one immunoreactive site on COUP-TF. Furthermore, there is a DNA clone containing the genetic coding regions of the COUP-TF protein.
