Assay Principle
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.
Assay Protocol
1. Prepare all reagents, samples and standards;
2. Add 100µ L standard or sample to each well. Incubate 2 hours at 37° C;
3. Aspirate and add 100µ L prepared Detection Reagent A. Incubate 1 hour at 37° C;
4. Aspirate and wash 3 times;
5. Add 100µ L prepared Detection Reagent B. Incubate 30 minutes at 37° C;
6. Aspirate and wash 5 times;
7. Add 90µ L Substrate Solution. Incubate 10-20 minutes at 37° C;
8. Add 50µ L Stop Solution. Read at 450nm immediately.
Assay Performance Time
3h
Sample Type
Serum, plasma, tissue homogenates, cell lysates, breast milk, cell culture supernates and other biological fluids
Detection Range
0.312-20ng/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 Inter-Assay: CV Inter-Assay: CV
Sensitivity
The minimum detectable dose of this kit is typically less than 0.131ng/mL
Stability
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.
Format
48T, 96T, 96Tx5, 96Tx10, 96Tx100
Specificity
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.
Product Name Synonym

Chemical Information

Water

Water is an oxygen hydride consisting of an oxygen atom that is covalently bonded to two hydrogen atoms. It has a role as an amphiprotic solvent, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a member of greenhouse gas, an Escherichia coli metabolite and a human metabolite. It is an oxygen hydride, a mononuclear parent hydride and an inorganic hydroxy compound. It is a conjugate base of an oxonium. It is a conjugate acid of a hydroxide.
