Used in biomedical research to detect and quantify levels of leucine-rich repeat protein 32 (LRRC32) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly valuable in studies related to immune regulation and TGF-β signaling, as LRRC32 plays a role in the activation of latent TGF-β, a key cytokine involved in immune tolerance and suppression. Researchers use this kit to investigate conditions like autoimmune diseases, cancer, and fibrotic disorders where TGF-β pathway dysregulation occurs. The assay provides a sensitive and specific means to monitor LRRC32 expression under experimental or clinical conditions, supporting both basic science and translational research.
