This assay has high sensitivity and excellent specificity for detection of Lactoferrin (LTF). No significant cross-reactivity or interference between Lactoferrin (LTF) and analogues was observed.

For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Samples: Serum, plasma, tissue homogenates, Cell lysates, saliva, milk,cell culture supernates and other biological fluids. Assay Type: Sandwich. Detection Range: 1.56-100ng/mL. Sensitivity: Typically less than 0.65ng/mL.

Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Lactoferrin (LTF) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Lactoferrin (LTF) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 . Intra-Assay: CV<10% . Inter-Assay: CV<12% . Assay Procedure Summary: 1. Prepare all reagents, samples and standards;. 2. Add 100uL standard or sample to each well. Incubate 2 hours at 37 degree C;. 3. Aspirate and add 100uL prepared Detection Reagent A. Incubate 1 hour at 37 degree C;. 4. Aspirate and wash 3 times;. 5. Add 100uL prepared Detection Reagent B. Incubate 30 minutes at 37 degree C;. 6. Aspirate and wash 5 times;. 7. Add 90uL Substrate Solution. Incubate 15-25 minutes at 37 degree C;. 8. Add 50uL Stop Solution. Read at 450nm immediately.

Principle of the Assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Lactoferrin (LTF). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Lactoferrin (LTF). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Lactoferrin (LTF), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of Lactoferrin (LTF) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

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. Antimicrobial, antiviral, antifungal and antiparasitic activity has been found for this protein and its peptides. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]

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. Protein type: Secreted; EC 3.4.21.-; Protease; Secreted, signal peptide.
