Used in biomedical research to quantify levels of human calcium-binding protein (CR) in tissue samples and biological fluids. Helps in studying neurological disorders, as CR is expressed in specific neurons and involved in calcium signaling. Supports research in neurodegenerative diseases such as Alzheimer's and Parkinson's by enabling assessment of neuronal health and loss. Also applied in cancer studies, particularly in tumors of the nervous system, where CR expression serves as a biomarker for certain cell types. The kit provides a reliable, sensitive method for detecting CR in ELISA format, facilitating high-throughput analysis in clinical and research laboratories.
