Used for the quantitative measurement of lysozyme (LZM) activity in chicken serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess innate immune responses in poultry, as lysozyme plays a key role in antimicrobial defense. It is commonly applied in veterinary research, poultry health monitoring, and immunology studies to evaluate the impact of infections, vaccines, feed additives, or stress on immune function in chickens. The assay provides a reliable and sensitive method for high-throughput analysis in laboratory settings.
