Abstract:
Carbohydrate Antigen CA19 - 9 has been widely utilized for diagnosis of different kinds of cancer such as pancreatic cancer, cancer of upper gastrointestinal tract. It may also be used as an indicator of pancreatic tissue damage that may be caused by diabetes.The method of enzyme linked immunosorbent assay (ELISA) for measurement CA19 - 9 in sera of patients with type 2 diabetes mellitus was developed using external CA19 - 9 antibody (competitive sandwich ELISA technique) and found to be suitable for the determination of a dissociation constant (Kd) of the binding of CA19 - 9 to its antibody in type 2 diabetic patients using scatchard plot. Objectives : - This study was performed to assess CA19 - 9 levels in sera of patients with type 2 diabetes mellitus with non - cancerous tissue by enzyme - linked immunosorbent assays (ELISA) and define the normal range (cutoff value) for the same marker in this patients also investigated the possible relationships of CA19 - 9 with fasting plasma glucose and HbA1c.This study present a new method for determination the dissociation constant (Kd) of the binding of CA19 - 9 to its antibody in type 2 diabetic patients using scatchard plot through development of ELISA (competitive sandwich ELISA technique).Different factors affecting this binding were extensively studied such as divalent cations, different halides, and Polyethylene (PEG - 6000).
