Normal Chicken IgY (egg-derived)

The antibody may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at -20°C. Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. An aliquot should be thawed slowly at ambient temperature and centrifuged to remove precipitate. This may result in a thin lipid layer floating on top and/or a visible precipitate. Removal of either will not affect the performance or the concentration of the product.
