Revvity, ALSU-TDNA-A-HV, AlphaLISA Human Total DNA PKcs Detection Kit, 100 Assay Points

Overview
DNA-PK, a nuclear DNA-dependent serine/threonine protein kinase, consists of two components, a DNA-dependent protein kinase, catalytic subunit (DNA PKcs) and an autoimmune antigen (KU). DNA-PKcs is inactive and relies on KU to direct it to DNA ends and trigger kinase activity where it is required for the non-homologous end joining pathway of DNA repair which rejoins double-strand breaks. DNA repair genes likely underlie many forms of cancer, and reduced expression of DNA PKcs is associated with cancers such as breast, prostate, and gastric.
The AlphaLISA SureFire Human Total DNA PKcs Detection Kit is a sandwich immunoassay for the quantitative detection of total DNA PKcs 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.
