The Ultra-sensitive Human TGF-β1 ELISA is a solid phase ELISA to measure the low concentration of human TGF-β1 at 0.5pg/mL level in cell culture supernatants, serum, and plasma, which is not possible to be detected with the regular ELISA. The main feature of this kit is the use of a novel approach to replace traditional methods. The kit is designed to ensure short steps, a short incubation time, and only one-step washing out. The measurement can be finished within 2 hours instead of the traditional 4-5 hours. The detection range is between 0.5-2048 pg/mL. The levels of human TGF-β1 samples are parallel to the standard curves obtained using the kit standards linearly. These results indicate that this kit can be used to determine relative mass values for natural human TGF-β1 protein.
