Lactoferrin, Bovine Protein | LTF protein
Lactoferrin, Bovine (bLF, LTF, lGIG12, HLF2, Lactoferrin, Lactotransferrin, LF, Talalactoferrin)
A great deal of structural information has been obtained about the lactoferrin molecule. It has been possible to relate this structural information to two striking in vitro properties of lactoferrin, its ability to bind a wide variety of metal ions with extremely high affinity, and its ability to bind to a number of different types of cells.
Lactoferrin is an iron binding protein. It is structurally similar to transferrin, the plasma iron transport protein; but lactoferrin has a much higher affinity for iron (250 fold). It is very abundant in colostrum and small amounts can also be found in tears, saliva, mucous secretions and in the secondary granules of neutrophils. It is made by mucosal epithelium and neutrophils and is released by these cells in response to inflammatory stimuli. Bacterial growth is inhibited by its ability to sequester iron and also permeabilize bacterial cell walls by binding to lipopolysaccharides through its N-terminus. Lactoferrin can inhibit viral infection by binding tightly to the viral envelope protein. This prevents cell-virus fusion by blocking the binding domain. Lactoferrin appears to activate host defense systems in part by stimulating the release of interleukin-8, a neutrophil activator. It may also be involved in antibody and interleukin synthesis, lymphocyte proliferation and complement activation.
NCBI and Uniprot Product Information
NCBI Description
This gene is a member of the transferrin family of genes and its protein product is found in the secondary granules of neutrophils. The protein is a major iron-binding protein in milk and body secretions with an antimicrobial activity, making it an important component of the non-specific immune system. The protein demonstrates a broad spectrum of properties, including regulation of iron homeostasis, host defense against a broad range of microbial infections, anti-inflammatory activity, regulation of cellular growth and differentiation and protection against cancer development and metastasis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2010]
Uniprot Description
LTF: Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. Belongs to the transferrin family. 2 isoforms of the human protein are produced by alternative promoter.

Product Notes
The LTF ltf (Catalog #AAA635052) is a Protein produced from Bovine colostrum and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Lactoferrin, Bovine, Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
