Fluorescent microspheres, beads and particles applications including blood flow determination, tracing, fluorimetry, in vivo imaging and calibration of imaging and flow cytometry instruments. Because our fluorescent dyes are incorporated in the bead and not just on the surface, they are relatively immune to photo bleaching and other environmental factors. Spheres are in difference sizes and fluorescences, high intensity, FITC, GFP, red, green, yellow, light yellow, sky blue, blue, orange, deep-red, Nile-red, purple, mcherry. The diameter of the spheres is usually higher than 50nm and in the micrometer um range.
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 Green Fluorescent Protein (GFP). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Green Fluorescent Protein (GFP). 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 Green Fluorescent Protein (GFP), 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 Green Fluorescent Protein (GFP) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
