Polyclonal secondary antibodies raised in goat (Cat.# W4011, W4021, W4031), rabbit (Cat.# G1351) or donkey (Cat.# V8051), immunoaffinity-purified using corresponding immobilized antigens and conjugated to horseradish peroxidase (HRP) enzyme. The Anti-Rabbit IgG (H+L), HRP Conjugate, Anti-Mouse IgG (H+L), HRP Conjugate and Anti-Human IgG (H+L), HRP Conjugate antibodies bind to both heavy and light chains for all IgG subclasses. As with all antibodies, in certain applications some species-dependent antigen-dependent cross-reactivity may be observed. The products (unless otherwise noted) are supplied as 1mg/ml solutions. A starting working dilution of 1:2,500 is suggested for most Western blot, dot blot and ELISA applications. The optimum concentration of secondary antibody depends on the application and will need to be empirically determined. Rabbit Anti-Chicken IgY, HRP Conjugate is a secondary antibody developed in rabbits against chicken IgY. Anti-Chicken IgY, HRP Conjugate recognizes both the heavy and light chains of IgY and has been validated for use in Western blots, dot blots and ELISAs. Donkey Anti-Goat IgG, HRP Conjugate is a secondary antibody developed in donkeys against goat IgG. Donkey Anti-Goat IgG, HRP Conjugate shows reactivity to goat and sheep IgG but minimal cross-reactivity to rabbit and mouse IgG. For Western blot applications with chromogenic detection use at a starting dilution of 1:10,000.|
