Used in biomedical research to quantitatively measure levels of calreticulin (CRT) in human biological samples such as serum, plasma, or cell lysates. This ELISA kit is particularly useful in studies related to autoimmune diseases, cancer, and cardiovascular conditions where CRT plays a role in immune response, cell adhesion, and calcium homeostasis. It enables researchers to assess CRT expression under various experimental conditions, supporting investigations into disease mechanisms, biomarker discovery, and therapeutic development. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of CRT in small sample volumes.
