The AlphaLISA™ SureFire® Ultra™ Human and Mouse Total PAX8 assay is a sandwich immunoassay for quantitative detection of total PAX8 in cellular lysates using Alpha Technology.
PAX8 is a transcription factor essential for the development and function of the thyroid gland, kidneys, and reproductive system. It regulates thyroid-specific genes such as thyroglobulin and thyroid peroxidase in response to TSH signaling. Aberrant PAX8 expression is observed in cancers, including ovarian, endometrial, and renal cancers, where it is used as a diagnostic marker and contributes to tumor progression.

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.
Adherent cell lines were seeded at 40,000 cells/well in a 96-well culture plate in complete medium and incubated overnight at 37°C, 5% CO2. Cells were lysed with 100 µL of Lysis Buffer. Suspension cells (Daudi, Ramos) were seeded at 100,000 cells/well (200 µL/well) in a 96-well culture plate in HBSS + 0.1% BSA, cells were spun down and lysed with 100 µL of Lysis Buffer. Suspension cell lysates were further diluted 1:2.5 with Lysis Buffer.
PAX8 Total levels were evaluated by AlphaLISA SureFire Ultra. For the detection step, 10 µL of cell lysate (approximately 4,000 cells) were transferred into a 384-well white OptiPlate, followed by 5 µL of Acceptor Mix and incubated for 1 hour at RT. Finally, 5 µL of Donor Mix was then added to each well and incubated for 1 hour at RT in the dark. The plate was read on an Envision using standard AlphaLISA settings.
Total PAX8 expression is dependent upon cell type. As expected, a very high level of expression was detected in OVCAR-3 cells, while signal was undetectable in Daudi, Ramos, AN3 CA, and PANC-1 cells.
