Used in biomedical research to quantify human red cell membrane proteins in biological samples. Enables study of erythrocyte structure and function, particularly in conditions affecting the red blood cell membrane such as hereditary spherocytosis, elliptocytosis, and other hemolytic anemias. Supports investigation into protein expression changes during disease progression, drug exposure, or oxidative stress. Widely applied in clinical labs and research settings for accurate, sensitive detection of membrane protein levels using ELISA methodology.
