Introduction
RayBio® Phospho-Tau (Ser202/Thr205) Quantitative ELISA kit is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in Human, Mouse & Rat serum, plasma and CSF. By determining phosphorylated Tau protein in your experimental model system, you can verify pathway activation in your sample. You can simultaneously measure numerous different samples without spending excess time and effort in performing a Western Blotting analysis.
This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human, Mouse & Rat phospho-Tau. An anti-pan Tau antibody has been coated onto a 96-well plate. Standard and Samples are pipetted into the wells and Tau present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-phospho-Tau (Ser202/Thr205) antibody is used to detect phosphorylated Tau. After washing away unbound antibody, HRP-conjugated streptavidin is pipetted into the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Tau (Ser202/Thr205) bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
