Used in immunological research to quantify C4 binding protein levels in biological samples. Helps in studying complement system regulation, particularly in autoimmune diseases, inflammation, and infectious conditions. The kit enables detection of C4BP in serum, plasma, or cell culture samples, supporting research into disease mechanisms and potential biomarkers. Commonly applied in studies related to systemic lupus erythematosus, sepsis, and age-related macular degeneration. Provides a reliable, sensitive, and specific method for measuring protein concentration in goat samples, aiding veterinary and comparative medicine research.
