    Why Use Chicken IgY?

  • Here are top 5 reasons:

    1. Higher titres against highly conserved mammalian gene products

    2. Double immunostaining is easier to perform

    3. Animal-friendly -- we purify the antibodies from eggs, not serum

    4. Large quantities of antibody - faster and cheaper

    5. Nearly unlimited quantities (again, because the antibodies come from eggs)

My proteins come out of solution (i.e., precipitates) when I put it in PBS. What should I do?

Insoluble proteins generally make great antigens, so don’t worry if your protein comes out of solution in PBS. Simply make an even suspension before aliquoting your antigen.
