Transferrin is a monomeric glycoprotein found in plasma at an average concentration of 250 mg/100 ml. The specific iron-binding protein in plasma, it has a role in the transportation and distribution of iron among the body organs, in iron metabolism and prevention of iron loss via the kidneys. Stored in bone marrow as Tf-bound iron, it also possesses bacteriostatic and fungistatic activity. Clinically, decreases in transferrin are observed in congenital disorders, newborns, inflammatory diseases, hypoproteinemias and nephrotic syndrome; increases are found in pregnancy, iron-deficiency anemias, and inoculation hepatitis. Transferrin is required by all types of cells in cultures for maximal growth. It is, therefore, an important transport factor used in defined culture media.

转铁蛋白是一种单体糖蛋白，存在于血浆中，平均浓度为250mg/100ml。血浆中的特异性铁结合蛋白，在铁在身体器官之间的运输和分布、铁代谢和预防肾脏铁流失方面发挥作用。它以Tf结合铁的形式储存在骨髓中，还具有抑菌和抑菌活性。临床上，先天性疾病、新生儿、炎症性疾病、低蛋白血症和肾病综合征中观察到转铁蛋白的减少；妊娠、缺铁性贫血和接种肝炎的发病率都有所增加。培养物中所有类型的细胞都需要转铁蛋白才能最大限度地生长。因此，它是特定培养基中使用的重要运输因素。
