Used in research settings to quantify phenylalanine ammonia-lyase (PAL) enzyme activity in chicken samples. This ELISA kit enables detection and measurement of PAL, which plays a role in phenylalanine metabolism and immune response studies. It is applied in poultry health research, helping investigate metabolic disorders, inflammatory conditions, and the impact of dietary or environmental factors on amino acid metabolism. The assay supports high-throughput analysis with reliable sensitivity, making it suitable for laboratory studies in veterinary science and agricultural research.
