I'm developing specific IgE detection kits for food, inhalant and others with immunoassay system(line blot).
It is difficut to choose membrane, allergens, the components of sample diluent, conjugate solution, enzyme solution and so on.
I'm suffering from false positive and low detection limit.
Is there any comments to help me?
* method : immunoassay, line blot
* capture : allergens
* conjugate : anti-human IgE- biotin
* enzyme : Streptavidin - AP
* substrate : BCIP, NBT
