Gallus gallus domesticus and other IgY antibodies have high affinity and are easy to collect from the yolk. Gallus gallus can produce 20 more than in rabbit polyclonal. The antibody will not bind to rheumatoid factor or protein or Fc regions. This gives very much reduced background very much suited for diagnostic applications. Papain will digest IgY’s to divalent Fab antibody fragments. IgY’s are suited for Elisa kit development, Immunohistochemistry and Western Blot.

Donkeys or Equus africanus asinus are often used as host species to raise antibodies. Even Equus ferus or horse antibodies are different than donkey antibodies since we know horse anti donkey IgGs. For immunohistochemistry it is useful to use an anti-donkey or horse block if your primary antibody is a donkey anti-human. We provide also anti-donkey as a species antibodies and ELISA kits.
