Description
Forkhead box protein M1 (FOXM1) is a transcription factor expressed throughout the cell cycle, rising in late G1-phase, reaching its apex in S-phase, and remaining there in G2/M and late M-phase. FOXM1 plays a significant role in multiple key cell cycle phases and is known as the master regulator of the cell cycle. The transcriptional network associated with FOXM1 regulates many processes, including stemness, cell survival, DNA damage repair, DNA replication, cell G1/S transition, cell cycle, cell proliferation, clonal formation, migration capacity, invasion, metastasis, and tumor initiation and progression. FOXM1 is found to be overexpressed in numerous malignancies such as breast, colorectal, hepatocellular, ovarian, lung, and pancreatic cancers.
The AlphaLISA SureFire Human Phospho-FOXM1 (Thr600) Detection Kit is a sandwich immunoassay for the quantitative detection of phospho-FOXM1 (Thr600) in cellular lysates, using Alpha Technology.

Phospho-AlphaLISA SureFire Ultra assay principle
The Phospho-AlphaLISA SureFire Ultra assay measures a target protein when phosphorylated at a specific residue in a biological sample (e.g. cell lysate).
The assay uses two antibodies which recognize the phospho epitope and a distal epitope on the target 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 for the generation of a luminescent Alpha signal. The amount of light emission is directly proportional to the quantity of phosphoprotein present in the sample.
Phospho-AlphaLISA SureFire Ultra two-plate assay protocol
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 enables cell viability and confluence to be monitored. In addition, lysates from a single well can be used to measure multiple targets.
Phospho-AlphaLISA SureFire Ultra one-plate assay protocol
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 robust AlphaLISA SureFire Ultra quality.
