鸡蛋包括胚胎发育所必需的营养物质和生长因子,还有从母鸡血液转移到蛋黄为小鸡提供免疫力的抗体。自从19世纪末期发现卵黄抗体(Ig Y),抗原特异性卵黄抗体被医学和研究领域广泛应用。Ig Y研究最有价值和前景的是被动免疫预防和治疗人类和动物疾病。Ig Y结构中Fc片段的存在使得其更加疏水,适合在卵黄这种高脂环境存在,而且Ig Y性质较稳定,口服不易发生过敏反应,在家禽腹泻和人类胃炎、肠炎及牙周炎等疾病的预防和治疗中有非常出色的表现。免疫母鸡可获得特异性抗体,卵黄中的Ig Y经稀释、凝集和离心等步骤纯化,制成含抗原特异性Ig Y产品,这种Ig Y产品致力于改善家禽和人类健康。
Eggs include nutrients and growth factors essential for embryonic development, as well as antibodies that migrate from hen blood to egg yolk to provide immunity to chickens. Antibody-specific yolk antibodies have been widely used in medicine and research since the egg yolk antibody (Ig Y) was discovered in the late 19th century. The most valuable and promising IgY study is passive immunization to prevent and treat human and animal diseases. The presence of the Fc fragment in the IgY structure makes it more hydrophobic and suitable for use in the high fat environment such as egg yolk. Ig Y is more stable and less susceptible to oral allergic reactions. In poultry diarrhea and other human diseases such as gastritis, enteritis and periodontitis In the prevention and treatment of very good performance. Immune hens obtain specific antibodies, Ig Y in the yolk diluted, agglutination and centrifugation and other steps purified to produce antigen-specific Ig Y products, this Ig Y products committed to improving poultry and human health.
