|Product name:||Human sTFR(Soluble Transferrin Receptor) ELISA Kit|
|Alternative Names:||CD71; TFR1; P90; TFRC; T9; Trfr; sTfR; Transferrin receptor protein 1, serum form|
|Sample type:||serum, plasma, tissue homogenates, cell lysates and other biological fluids|
|Research Area:||Signal transduction;CD & Adhesion molecule;Tumor immunity;Infection immunity;|
|Test 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 Soluble Transferrin Receptor(sTFR). Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Soluble Transferrin Receptor(sTFR). 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 Soluble Transferrin Receptor(sTFR), 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 Soluble Transferrin Receptor(sTFR) in the samples is then determined by comparing the OD of the samples to the standard curve.|
|Concentration (pg/mL)||OD||Corrected OD|
Intra-assay Precision (Precision within an assay)：CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays)：CV%<10%
Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
