Summary for Patent: 5,312,628
Title: Isolation of a soluble 42 KD pancreatic islet cell autoantigen
Abstract:A method of isolating soluble pancreatic islet antigen employs extraction with a non-ionic detergent and fractionation on a gel filtration column. Fractions are screened for high immunoreactivity with diabetic serum which is positive for ICA immunofluorescence when tested on tissue sections of a pancreas from a human blood group O donor. The isolated soluble antigen is suitable for measuring autoantibodies in both complement fixation assays as well as ELISA-type and immunoblotting formats. Methods of using isolated soluble antigen to test serum for autoantibodies are also taught.
