Hardy Diagnostics CAMP Spot Test Reagent is used to rapidly determine an organism’s ability to produce the protein CAMP factor. CAMP factor is a diffusible, extracellular protein which acts synergistically with staphylococcal beta-hemolysin (beta-lysin). The test is particularly useful as part of the identification of Streptococcus agalactiae (group B streptococci), and Listeria monocytogenes.
