Used in biomedical research to quantify transthyretin (TTR) levels in human serum, plasma, or cerebrospinal fluid. Helps in studying thyroid hormone transport, as TTR is responsible for carrying thyroxine and retinol-binding protein. Widely applied in diagnosing and monitoring TTR-related amyloidosis, a condition where misfolded TTR forms amyloid deposits in tissues. Also used in clinical research to evaluate the effectiveness of therapies aimed at stabilizing TTR or reducing its production. Supports studies on malnutrition, inflammation, and liver diseases, where TTR levels may be altered. Provides a reliable, high-throughput method for measuring TTR concentration in large sample sets.
