EnzyFluo™ Human/Mouse RB(T821/826) Phosphorylation ELISA Kit

Application

• For determination of RB(T821/826) phosphorylation status in whole cells and evaluation of pathway modulation by activators, inhibitors, siRNA, etc.

Key Features

• New and improved. Total assay time reduced from the standard 21 hours to 6.5 hours (hands-on time 2.5 hrs).
• Simple and convenient. Cells are directly cultured in 96-well plates. No cell lysis is necessary.
• Accurate and high-throughput. Protein phosphorylation is normalized to total cellular protein in the same well, greatly minimizing well-to-well variations. It can be readily automated as a high-throughput 96-well plate assay for thousands of samples per day.

More Details

• PROTEIN PHOSPHORYLATION plays key role in regulating protein activity within cells. A large number of protein kinases and phosphatases are known to be involved in a variety of signal transduction pathways. A rapid assay capable of monitoring such signal transduction pathways, target protein phosphorylation status, and drug effects is highly desirable in life science research and drug discovery. The RetinoBlastoma tumor suppressor protein (Rb, RB1, pRb, retinoblastoma 1, OSRC, PPP1R130, p105-Rb, pp110, retinoblastoma protein, RB transcriptional corepressor 1, p110-RB1) regulates cell differentiation, apoptosis, and cell cycle control. BioAssay Systems’ RB(T821/826) Phosphorylation ELISA Kit provides a rapid and sensitive assay for measuring the phosphorylated protein pRB(T821/826) in cultured cells and normalizes the level of phosphorylation to the total protein content in the same well. This simple and efficient assay eliminates the need for cell lysate preparation and can be used to study the underlying signal pathway and effects of inhibitors, siRNA, or activators on the pathway. In this assay, cells grown in a 96-well plate are fixed and permeabilized. The phosphorylation of RB(T821/826) is measured using a specific primary antibody followed by a HRP-conjugated secondary antibody with a fluorogenic substrate, and a fluorescent reagent that measures the total protein in the same well.
