Used in research settings to quantify levels of PNPT1 protein in human biological samples such as cell lysates, tissue extracts, or serum. This ELISA kit enables scientists to study the expression and regulation of PNPT1, which plays a role in mitochondrial RNA processing and antiviral immune responses. It is particularly useful in studies related to mitochondrial disorders, neurodegenerative diseases, and innate immunity. The assay provides a sensitive and specific method for detecting PNPT1, supporting biomarker discovery and mechanistic investigations in cellular and molecular biology.
