lambda phage library 

Lambda phage genomic library contributes to various applications, especially for antigen discovery and immune response investigations. By constructing genome libraries derived from specific pathogens (i.e. virus, bacteria or organ) and screening against the whole antibody repertoire of infected individuals, efficient identification of a large panel of antigenic regions can be achieved. Therefore, lambda phage genome library provides a highlight for improving diagnosis, prophylaxis, and therapy for many life-threatening diseases.
