Chicken IgY Purification Kit (VS-0824-WK24)

CAT#: VS-0824-WK24

This chicken IgY purification kit purifies chicken antibodies from hen egg yolks using a unique delipidation reagent to separate protein from lipid and a precipitation reagent to selectively isolate the IgY fraction. With this kit, 80-120mg of 90% pure IgY can be easily obtained from each egg
yolk.

  • Background
  • The eggs of immunized chickens are an economical and abundant source of polyclonal antibodies. A single egg may contain as much antibody as can be obtained from an average bleed of a rabbit. Immunogen-specific antibody generally is from 1-10% of the total IgY in each egg. The eggs from immunized chickens offer a nearly continual daily source of milligram quantities of specific polyclonal antibody. When using chickens, there is a higher potential of producing antibodies to mammalian antigens than when using rabbits or goats. In addition, chicken IgY does not cross-react with mammalian IgG and does not bind bacterial or mammalian Fc receptors. It has been reported, that nonspecific binding is reduced and the need to do cross-species immunoabsorptions is eliminated when using chicken antibodies
