    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)

How much antigen should I send?

For two hens (i.e., the minimum number we recommend), we suggest 4.0 mg in a total volume of 4.0 mls of PBS or TBS (i.e., 1.0 mg/ml). It is best if the protein is placed in four 1.0 ml aliquots and frozen on dry ice. If you only have a precious amount of protein, we can probably get by with a concentration of 0.5 mg/ml.
