The TAU [pT231] Human ELISA kit is designed to detect and quantify the level of TAU protein phosphorylated at threonine residue 231. This assay is intended for the detection of TAU [pT231] from human cerebrospinal fluid and cell lysates using 96-well plates and a microplate reader.
• Easy to run • More sensitive than Westerns • Convenient precoated, removable 8-well strips
Easy-to-Run Sandwich ELISA A monoclonal capture antibody specific for TAU has been coated onto the wells of the 96-well plate provided. During the first incubation, standards of known TAU [pT231] content and unknown samples are pipetted into the wells and the TAU antigen binds to the immobilized (capture) antibody. After washing, a rabbit antibody specific for TAU phosphorylated at threonine 231 is added to the wells. During the second incubation, this antibody serves as a detection antibody by binding to the immobilized TAUprotein captured during the first incubation. After washing, a horseradish peroxidase labeled anti-rabbit IgG is added. This binds to the detection antibody to complete the four member sandwich. After a third incubation and washing to remove all the unbound enzyme, a substrate solution (TMB) is added, which is acted upon by the bound enzyme to produce color. The intensity of this colored product is directly proportional to the concentration of TAU [pT231] present in the original specimen and the optical density can be read on a standard microplate reader. The total assay incubation time is only 4 hours.
Detect Low Expressing Proteins and Use Less Sample ELISA kits designed to measure intracellular signaling targets are 2–10X more sensitive than Western blotting. The improved sensitivity enables you to detect low-expressing proteins that otherwise may not be distinguishable from background. In addition, the amount of sample needed to run the assay is less than what is needed for Western blots.
Ready-to-Use Tau [pT231] Human ELISA Kit Contains These Reagents, Buffers, and Supplies:
• TAU Antibody-Coated 96-Well Plate • TAU [pT231] Standard • Standard Diluent Buffer • TAU [pT231] Detection Antibody • anti-rabbit IgG-HRP (100X) • HRP Diluent • Wash Buffer Concentrate (25X) • Stabilized Chromogen, TMB • Stop Solution • Plate Covers • Detailed protocol with validation tests
Convenient Kit Format The kit comes with a capture antibody precoated to the plate, eliminating an overnight coating process. The plates are machine coated to provide low variability well-to-well. Furthermore, the plate comes as removable 8-well strips allowing you to run as few samples as you want. In addition, the standards provided in the kit can be used to obtain quantitative results from the standard curve and/or can be used as a positive control.
Rigorous Validation Each ELISA kit is validated for sensitivity, specificity, precision, and lot-to-lot consistency. See protocol insert for more information on validation.
