Levels of Lactoferrin in human donors.
Ten individual healthy male donors and one pooled sample (n = 50) were evaluated for the presence of Lactoferrin in serum using this assay. Results were interpolated from the standard curve in Sample Diluent NS and corrected by sample dilution (1 : 75). In the 10 individual donors, the mean level of Lactoferrin is 350.3 ng/mL with a range of 106.2 – 627.7 ng/mL and a standard deviation of 159.4 ng/mL.

Linearity of dilution of native Lactoferrin in human plasmas.
Native human Lactoferrin protein was measured in citrate plasma (1 : 128), EDTA plasma (1 : 150), and heparin plasma (1 : 64) diluted in a 2-fold dilution series in Sample Diluent NS. The interpolated dilution factor corrected values are graphed (mean +/- SD).

Linearity of dilution of native Lactoferrin in serum and urine and spiked Lactoferrin in media.
Native human Lactoferrin protein was measured in serum diluted 1 : 64 and urine diluted 1 : 8 in Sample Diluent NS prior to a 2-fold dilution series in Sample Diluent NS. Purified human Lactoferrin protein was spiked into cell culture media diluted 1 : 20 prior to a fold dilution series in Sample Diluent NS. The interpolated dilution factor corrected values are graphed (mean +/- SD).

Product details
Lactoferrin in vitro CatchPoint SimpleStep ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Lactoferrin protein in human serum, plasma, milk, urine, saliva, and cell culture supernatants.
This CatchPoint SimpleStep ELISA kit has been optimized for Molecular Devices Microplate Readers. Click here for a list of recommended Microplate Readers.
If using a Molecular Devices' plate reader supported by SoftMax® Pro software, a preconfigured protocol for these CatchPoint SimpleStep ELISA Kits is available with all the protocol and analysis settings at www.softmaxpro.org.
The CatchPoint SimpleStep ELISA employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530/570/590 nm Excitation/Cutoff/Emission.
Transferrins are iron binding transport proteins which can bind two Fe3+ ions in association with the binding of an anion, usually bicarbonate. 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).

Biological function summary
Lactoferrin 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.
Pathways
Lactoferrin 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.
