Sequestome-1, also known as ubiquitin binding protein p62 or SQSTM1 p62, is an autophagosome cargo protein that directs selective autophagy toward proteins that bind to it. SQSTM1 p62 is an adaptor protein that can attach to cargo proteins that have been ubiquitinated because it has a higher affinity for ubiquitin chains post-phosphorylation. After lysosomal fusion, the contents of phagosomes are eliminated, removing ubiquitinated proteins or mitochondria associated with SQSTM1 p62 proteins. Alzheimer's disease, Huntington's disease, NASH, and many cancers are all linked to SQSTM1 p62.
The AlphaLISA SureFire Human and Mouse Phospho-SQSTM1 p62 (Ser403) Detection Kit is a sandwich immunoassay for the quantitative detection of phospho-SQSTM1 p62 (Ser403) in cellular lysates, using Alpha Technology.
The Phospho-AlphaLISA SureFire Ultra assay measures a protein target when phosphorylated at a specific residue.
The assay uses two antibodies which recognize the phospho epitope and a distal epitope on the targeted protein. AlphaLISA assays require two bead types: Acceptor and Donor beads. Acceptor beads are coated with a proprietary CaptSure™ agent to specifically immobilize the assay specific antibody, labeled with a CaptSure tag. Donor beads are coated with streptavidin to capture one of the detection antibodies, which is biotinylated. In the presence of phosphorylated protein, the two antibodies bring the Donor and Acceptor beads in close proximity whereby the singlet oxygen transfers energy to excite the Acceptor bead, allowing the generation of a luminescent Alpha signal. The amount of light emission is directly proportional to the quantity of phosphoprotein present in the sample.
The two-plate protocol involves culturing and treating the cells in a 96-well plate before lysis, then transferring lysates into a 384-well OptiPlate™ plate before the addition of Phospho-AlphaLISA SureFire Ultra detection reagents. This protocol permits the cells viability and confluence to be monitored. In addition, lysates from a single well can be used to measure multiple targets.
Detection of Phosphorylated target protein with AlphaLISA SureFire Ultra reagents can be performed in a single plate used for culturing, treatment, and lysis. No washing steps are required. This HTS designed protocol allows for miniaturization while maintaining AlphaLISA SureFire Ultra quality.
