Receptor tyrosine-protein kinase erbB3, also known as HER3 (human epidermal growth factor receptor 3) is a membrane bound protein that is encoded by the ERBB3 gene. ErbB3 has a neuregulin binding domain, however, does not have an active kinase domain and can therefore bind this ligand but is unable to convey the signal into the cell through protein phosphorylation. ErbB3 forms heterodimers with other EGF receptor family members which have kinase activity. Heterodimerization leads to the activation of pathways that trigger cell proliferation or differentiation. ErbB3 overexpression is an indicator of poor patient prognosis in human breast cancer and has also been reported in other cancers such as prostate and bladder.
The AlphaLISA SureFire Ultra Human Total ErbB3 Detection Kit is a sandwich immunoassay for the quantitative detection of total ErbB3 in cellular lysates, using Alpha Technology.
The Total-AlphaLISA SureFire Ultra assay measures the expression level of a protein target in a cell lysate.
The Total-AlphaLISA SureFire Ultra assay uses two antibodies which recognize two different distal epitopes 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 targeted 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 protein 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 Total-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 Total 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.
