Lactoferrin is a member of the transferrin family and is a major iron-binding and multifunctional protein found in exocrine fluids such as breast milk and mucosal secretions. High levels of Lactoferrin are found in saliva and tears, intermediate levels in serum and plasma, and low levels in urine. The canonical sequence of Lactoferrin (known as isoform 1) is 710 amino acids in length and runs at 78.2 kDa. Isoform Delta-Lactoferrin (or DeltaLF) is missing amino acids 1 – 44 of the canonical sequence. Mouse and rat Lactoferrin are 71% and 62% identical to human Lactoferrin, respectively.Lactoferrin possesses antibacterial, antiviral, anti-inflammatory, and immunoregulatory properties. The presence of Lactoferrin in neutrophils and the release of Lactoferrin during inflammation suggest that Lactoferrin is involved in phagocytic killing and immune responses. Additionally, Lactoferrin mediates bacteriostasis through its ability to sequester free iron and inhibit microbial growth. Lactoferrin also directs bactericidal properties leading to the release of lipopolysaccharides from the bacterial outer membrane. Furthermore, Lactoferrin may play a role in the regulation of bone growth because it has anabolic, differentiating, and anti-apoptotic effects on osteoblasts and can also inhibit osteoclastogenesis. Salivary Lactoferrin plays an important role in protecting the oral cavity against several oral pathogens including Streptococcus mutans. Additionally, increased levels of Lactoferrin in fecal samples is used as a marker of active inflammatory bowel disease (IBD).\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nLactoferrin also known as lactotransferrin is an iron-binding glycoprotein with a molecular weight of about 80 kDa. It predominantly exists in mammalian milk particularly in high concentrations in colostrum and is also found in various epithelial secretions such as saliva tears and nasal fluids. The liver and neutrophils also produce lactoferrin and it plays a significant role in the body's primary defense system. As an antibacterial agent lactoferrin sequesters free iron to limit bacterial growth and disrupt biofilms assisting in the protection against microbial invasions.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nLactoferrin exhibits multiple functions beyond its antimicrobial properties. It contributes to immunomodulation by binding to specific receptors on immune cells enhancing phagocytosis and influencing cytokine production. Also it possesses anti-inflammatory and antioxidant properties. Lactoferrin interacts with cellular components including glycosaminoglycans and lipoproteins impacting the activity and expression of proteins within signaling and metabolic pathways. This multifaceted role places it as a critical participant in both innate and adaptive immune responses although it does not form part of a stable protein complex.\u003cbr\u003e\nPathways\u003cbr\u003e\nLactoferrin plays a significant role in the iron metabolism and immune response pathways. It tightly interacts with the transferrin receptor modulating iron uptake and distribution across tissues which helps prevent iron overload and oxidative stress. Furthermore lactoferrin links with the toll-like receptor pathways particularly TLR4 which enables the modulation of innate immune responses against pathogens. By influencing nuclear factor kappa B (NF-kB) signaling lactoferrin impacts inflammation and immune responses working together with proteins such as ferritin and hepcidin.\u003cbr\u003e\nLactoferrin has relevancy to diseases like anemia of chronic disease and inflammatory bowel disease (IBD). Its role in regulating iron homeostasis makes it essential for preventing anemia associated with chronic inflammation. Lactoferrin mitigates dysregulated immune responses in IBD potentially reducing inflammation and promoting gut health. Disease-modifying properties of lactoferrin connect it to glycoproteins like transferrin and inflammatory mediators demonstrating its potential therapeutic importance.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843535851689,"sku":"ab200015","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab200015","provider":"Iright","version":"1.0","type":"link"}
