KLH ELISA kits are assays designed to detect keyhole limpet hemocyanin, a large copper-containing protein molecule found in the hemolymph of the mollusk Megathura crenulate. It is a potent immunogen that is used as a carrier protein for haptens and in the production of antibodies. They are used for the production of vaccines and treatment of human bladder cancer. KLH is advantageous as it has numerous epitopes, large, and is phylogenetically distant from mammalian proteins, which help to reduce false positives.
