NKX3-1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level NK3 Homeobox Protein 1 (NKX3-1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level NK3 Homeobox Protein 1 (NKX3-1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

BAPX2; homeobox protein NK-3 homolog A; homeobox protein Nkx-3.1; NK homeobox, family 3, A; NK3 transcription factor homolog A; NK3 transcription factor related, locus 1; NKX3; NKX3.1; NKX3A.

Transcription factor, which binds preferentially the consensus sequence 5'-TAAGT[AG]-3' and can behave as a transcriptional repressor. Plays an important role in normal prostate development, regulating proliferation of glandular epithelium and in the formation of ducts in prostate. Acts as a tumor suppressor controlling prostate carcinogenesis, as shown by the ability to inhibit proliferation and invasion activities of PC-3 prostate cancer cells.

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 NK3 Homeobox Protein 1 (NKX3-1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to NK3 Homeobox Protein 1 (NKX3-1) . 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 NK3 Homeobox Protein 1 (NKX3-1), 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 NK3 Homeobox Protein 1 (NKX3-1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
