First identified in 1969, avian IgY has now become a well characterized research reagent commercially available. For decades, extensive research has been carried out on its biological function, physiochemical property, production and purification. More than a alternative to mammalian IgG, IgY possesses several advantages over polyclonal antibodies raised in mammals, such as a much more hygienic, cost efficient, and humane manufacturing process. Abnova now brings you our latest series of avian antibodies for your choice. Please visit the webpage "New Chicken Antibodies" for more information.
