Lactoferrin (LF) is an iron-binding glycoprotein in mammals, which has many functions, such as broad-spectrum anti-infection, two-way immune regulation, iron balance in vivo, growth of bifidobacteria, intestinal flora balance and so on. It can be divided into secretory lactoferrin and serotype lactoferrin.

Secretory lactoferrin: secreted by mammary gland, bronchial gland and salivary gland, and widely exists in exocrine fluids such as milk, tears, saliva, respiratory tract and digestive tract together with sIgA. It is an important part of the body's nonspecific immune system and a natural broad-spectrum antibacterial agent and immune factor.

Serotype lactoferrin: secreted by secondary lysosomal particles of mature neutrophils. Serum lactoferrin level reflects the secretory activity of neutrophils, which has important immunological significance.
