Abstract
This invention deals with genetically engineered immunoglobulins with affinity and specificity for (human) glycated albumin. The invention is directed to the DNA which encodes the immunoglobulins. The DNA sequence can be manipulated to produce chimeras and fragments such as Fab, F(ab').sub.2 or ScFv. The immunoglobulins can be produced by recombinant DNA methods and readily purified. The invention also provides a novel and improved method for treating the complications of diabetes.
Claims4
An isolated DNA molecule that comprises DNA encoding an IgG molecule having specificity for glycated albumin as defined by a monoclonal antibody produced by cell line ATCC 9596 and comprising a complementarity determining region of murine origin, a variable framework region of human origin (Seq Id. No:
- 3,4) and a constant region of human origin.
An isolated DNA molecle that comprises DNA encoding an immunoglobulin F(ab').sub.2 molecule having specificity for glycated albumin as defined by a monoclonal antibody produced by cell line ATCC 9596 and comprising a complementarity determining region of murine origin, a variable framework region of human origin (Seq Id. No:
- 3,4) and a constant region of human origin.
An isolated DNA molecule that comprises DNA encoding in immunoglobulin Fab molecule having specificity for glycated albumin as defined by a monoclonal antibody produced by cell line ATCC 9596 and comprising a complementarity determining region of murine origin, a variable framework region of human origin (Seq Id. No:
- 3,4) and a constant region of human origin.
An isolated DNA molecule that comprises DNA encoding a single chain immunoglobulin (ScFv) molecule having specificity for glycated albumin as defined by a monoclonal antibody produced by cell line ATCC 9596 and comprising a complementarity determining region of murine origin and a variable framework region of human origin (Seq Id. No:
- 5).
