Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (PubMed:20949621). Plays an important role in the regulation of cell proliferation (PubMed:23698361, PubMed:22711838). Plays a role in promoting oncogenic events by inducing transcriptional silencing of tumor suppressor genes (TSGs) in colorectal cancer (CRC) cells in a ZNF304-dependent manner (PubMed:24623306).

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 V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS). 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 V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS), 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 V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) were tested on 3 different plates, 8 replicates in each plate.
