Lactoferrin (LF, Lactotransferrin, LTF, Talalactoferrin) (Biotin)

Exocrine organs produce various secretions, each with its characteristic function. Proteins found in secretions may be divided into two groups: those specific for the particular secretion, and plasma proteins independent of the type of exocrine cells. Lactoferrin belongs to the first group. It is an iron containing protein with a molecular weight of 75000 and it is antigenically different from transferrin. Lactoferrin has a slight antimicrobal action. Originally identified in milk, its presence has also been demonstrated in other secretions as saliva, semen and tears.
