Revvity, ASBF-TNFKB-A10K, AlphaLISA Biotin-Free Human and Mouse Total NF-κB p65 Detection Kit, 10,000 Assay Points

Overview
NF-κB p65 (RelA) is a key subunit of the NF-κB transcription factor complex, which regulates genes involved in inflammation, immune responses, apoptosis, and cell proliferation. In its inactive state, p65 is sequestered in the cytoplasm by IκB proteins. Upon activation by pro-inflammatory stimuli such as TNFα, IL-1, or pathogen-associated signals, IκB is phosphorylated and degraded, allowing NF-κB p65 to translocate into the nucleus and drive transcription of target genes. Dysregulation of NF-κB p65 activity contributes to chronic inflammation, autoimmune diseases, and cancer, particularly in driving tumor-promoting inflammation and resistance to apoptosis.
The AlphaLISA SureFire Biotin-Free Human and Mouse Total NF-κB p65 Detection Kit is a sandwich immunoassay for the quantitative detection of total NF-κB p65 in cellular lysates, using Alpha Technology.

How it works
Total-AlphaLISA SureFire Ultra Biotin Free assay principle
The Total-AlphaLISA Surefire Ultra Biotin Free assaymeasures 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 a proprietary CaptSure 3 agent to capture one of the detection antibodies, which is labeled with CaptSure 3 tag. 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.

 

Total-AlphaLISA SureFire Ultra Biotin Free 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 Biotin Free 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.

Total-AlphaLISA SureFire Ultra one-plate assay protocol
Detection of Total target protein with AlphaLISA SureFire Ultra Biotin Free 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.
