Description
Inhibitor of nuclear factor kappa-B kinase subunit β (IKKβ) is a protein subunit of IkB kinase, which is an enzyme complex involved in propagating cellular response to inflammation. Activated IKKβ phosphorylates IkBα, preventing IkBα from inhibiting NF-kB which then frees NF-kB and allows it to enter the nucleus of the cell, where it activates various genes involved in inflammation and other immune responses. The IKKβ signaling pathway is associated with numerous therapeutic areas, including diseases such as multiple sclerosis, rheumatoid arthritis, psoriasis, and many types of cancers.
The AlphaLISA SureFire Ultra Human Total IKKβ Detection Kit is a sandwich immunoassay for the quantitative detection of total IKKβ in cellular lysates, using Alpha Technology.

Total-AlphaLISA SureFire Ultra assay principle
The Total-AlphaLISA SureFire Ultra assay measures the expression level of a target protein in a biological sample (e.g. cell lysate).
The Total-AlphaLISA SureFire Ultra assay uses two antibodies which recognize two different distal epitopes 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 target 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 protein present in the sample.
Total-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 Total-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.
Total-AlphaLISA SureFire Ultra one-plate assay protocol
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 robust AlphaLISA SureFire Ultra quality.
