Affinity purified polyclonal antibody to the Listeria genus made in goat and labeled with alkaline phosphatase. Isolated from a serum pool of goats immunized with different strains of heat-killed whole cells of Listeria. This antibody is broadly reactive to Listeria and recognizes all 10 Listeria species tested in our laboratory. The intensity of reaction may vary with the strain of Listeria tested. It may also show occasional low level cross-reactivity to Staphylococcus and Streptococcus species under certain test conditions.
Product is in lyophilized form. Each lot is tested to assure specificity and lot-to-lot consistency using an in-house ELISA assay.
