Human OLFM4(Olfactomedin 4) ELISA Kit

May promote proliferation of pancreatic cancer cells by favoring the transition from the S to G2/M phase. In myeloid leukemic cell lines, inhibits cell growth and induces cell differentiation and apoptosis. May play a role in the inhibition of EIF4EBP1 phosphorylation/deactivation. Facilitates cell adhesion, most probably through interaction with cell surface lectins and cadherin Assay Type: Sandwich. Sensitivity: 1.12 ng/mL. Standard: 200 ng/mL. Detection range: 3.13-200 ng/mL. Sample type: serum, plasma, tissue homogenates and other biological fluids. Assay length: 3.5h. Research Field: Tumor 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 Human OLFM4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human OLFM4. 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 Human OLFM4, 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 Human OLFM4 in the samples is then determined by comparing the OD of the samples to the standard curve.
