چکیده
Introduction: Chronic kidney disease is a worldwide health problem and Glomerular filtration rate (GFR) is the most frequently used criteria in the assessment of rental function. Cystatin C as a member of type 2 cystatin superfamily and cysteine-protease inhibitor is found in high concentrations in all biological fluids. This study is aimed to study cystatin C as a potent biomarker for clinical measurement of renal disorders and other diseases. Materials and Methods: In this study, the human cystatin C construct was analyzed by bioinformatics software. It was cloned and expressed to produce an appropriate antigen for anti-cystatin C (anti-Cys C) obtained from mice Balb/C as a crucial point in the improvement of an enzyme-linked immunosorbent assay (ELISA) method. Serum samples were given from 32 hospitalized patients with renal failure and cardiovascular disease and non-hospitalized patients were tested by ELISA method using anti-Cys C obtained from mice Balb/C. Results: Our findings indicated 0.36-2.4 mg/L as the best conclusion for antigen cystatin C in patients’ sera and 1/50 dilution for anti-Cys C obtained from mice Balb/C and showed a relationship between patients with high creatinine and high concentration of cystatin C. In case of five cardiovascular disease patients with normal upper limit of Creatinine we obtained cystatin C lower than kidney failure and raising of cystatin C in 6 patients with increased TSH were seen. Conclusions: Polyclonal anti-Cys C antibodies were obtained through the immunization of Balb/C mice can be employed as an anti-Cys C in ELISA for diagnosis of some renal dysfunction.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
