鸡胚提取物是从生长9-12天的鸡胚中提取的，用于组织培养中的生长因子补充成分。
鸡胚提取物是一种优质蛋白质，蛋白质含量高，氨基酸模式与人体的氨基酸模式一致，具有丰富的矿物元素和维生素，具有很高的营养价值。它的K、Fe、Se矿物元素和维生素A、D、B2等含量也很高。这使得它不但具有补充这些营养素的作用，而且，还可能有一些保健功能。已有实验证明，鸡胚提取物能有效地改善小鼠的硒营养不良状态，提高低硒小鼠的GPX活性，清除过氧化物产物MDA。有文献提出鸡胚提取物还具有调节血脂的功能。
在磷酸盐缓冲盐水中以50%的提取物进行处理，补充100IU/mL青霉素、100ug/mL链霉素和2.5ug/mL两性霉素。将液体提取物无菌过滤至0.2µm，并在10mL等分试样中冻干。这种冻干粉的无菌性无法保证，应在重组后再次进行无菌过滤。

The product is prepared in conformance with cGMP.

The proprietary process utilises 9-12 day eggs collected from registered flocks and found to be free from clinical signs of notifiable diseases.
