Spike solutions supplement Immunolab´s allergen ELISA kits and help establish routine test schemes in a laboratory or facilitate the validation of new sample types. They are made from the same reference material as used for the calibrators of the corresponding ELISA test kit, but come in higher concentration. Since no international or even industry wide reference materials are available for food allergens, spike solutions provide for convenient to use reference samples that fit into Immunolab’s test scheme.
