Used in research to quantify Klotho protein levels in biological samples such as serum, plasma, and cell culture supernatants. Enables studies on aging, kidney function, and age-related diseases by providing a reliable method to measure Klotho expression. Commonly applied in preclinical studies investigating metabolic disorders, cardiovascular health, and neurodegenerative conditions. Supports high-throughput screening in drug development where Klotho modulation is a therapeutic target. Provides sensitive and specific detection, allowing researchers to monitor changes in protein levels under experimental conditions.
