Used in biomedical research to detect and quantify levels of Reticulocalbin 3 (RCN3) in human biological samples such as serum, plasma, and cell lysates. This ELISA kit is particularly useful in studying endoplasmic reticulum-related cellular processes, protein trafficking, and calcium signaling. It supports research into diseases associated with ER stress, including neurodegenerative disorders, diabetes, and certain cancers. The kit enables high sensitivity and specificity, making it suitable for both basic research and diagnostic development in laboratory settings. Not intended for clinical diagnostic use.
