Used in immunological research to detect and quantify Chicken B Factor (BF), an important component of the avian complement system. The kit enables researchers to study immune responses in poultry, assess the health status of chicken flocks, and support vaccine development. It is commonly applied in veterinary diagnostics, poultry farming research, and studies related to disease resistance in birds. The ELISA format allows for high-throughput analysis of serum, plasma, or tissue samples with high sensitivity and specificity.
