A novel, cost-effective and efficient chicken egg IgY purification procedure

► A quick, cheap and effective way to purify lab-scale chicken antibodies from eggs. ► Using pectin, carrageenan and CaCl2 to delipidate and (NH4)2SO4 to precipitate IgY. ► We obtained approximately 60 mg of active antibody per egg yolk. ► The antibodies were approximately 80% pure and cost a fraction to isolate compared the commercial kits.
