Revvity, ALSU-TCFOS-A10K, AlphaLISA Human Total c-FOS Detection Kit, 10,000 Assay Points

Overview
Protein c-Fos is encoded by the FOS gene, a proto-oncogene that is the human homolog of the retroviral oncogene v-fos. The Activator Protein-1 (AP-1) complex is formed when c-Fos and c-Jun form a heterodimer. This complex binds DNA at specific AP-1 sites in the promoter and enhancer regions of target genes, converting extracellular signals into changes in gene expression. Additionally, posttranslational alterations brought on by phosphorylation by various kinases, such as MAPK, CDC2, PKA, or PKC, regulate its activity. C-Fos plays an important role in numerous cellular functions, including cell proliferation, differentiation, survival, genes associated with hypoxia, and has been found to be overexpressed in a variety of cancers.
 
The AlphaLISA SureFire Ultra Human Total c-FOS Detection Kit is a sandwich immunoassay for the quantitative detection of total c-FOS in cellular lysates, using Alpha Technology.

How it works
Total-AlphaLISA SureFire Ultra assay principle

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.

 

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 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 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.
