In addition to a catalog of ELISA kits and monoclonal antibodies, AffinityImmuno Inc. provides a custom chicken polyclonal antibody service. Chicken polyclonal antibodies have many advantages when compared to mammalian antibodies such as high yields, high affinity, no binding to mammalian Fc receptors, and no binding by rheumatoid factor or complement proteins in mammalian samples.

Recently, AffinityImmuno Inc. has launched a series of reagents in response to the COVID19 pandemic which includes various polyclonal antibodies, virus spike protein ELISA kit, and a virus neutralization test.
