Chicken

When raised in chickens, antibodies show unique advantages compared to mammalian hosts. These IgY polyclonal antibodies recognize human, goat, and rabbit proteins with minimal interference from mammalian IgG, which improves clarity in assays. They are commonly delivered as purified fractions, often conjugated with HRP, biotin, or fluorescent dyes, and are applied in ELISA, Western Blot, and immunohistochemistry. Research studies highlight chicken-derived antibodies as reliable reagents for diagnostics and protein analysis, especially when cross- reactivity must be avoided.
