Revvity, ALSU-TCYCE1-A50K, AlphaLISA Human Total Cyclin E1 Detection Kit, 50,000 Assay Points

Overview
Cyclin E1 (CCNE1) is a member of the highly conserved cyclin family, whose members have various roles in the cell cycle. CCNE1 forms a complex with cyclin-dependent kinase 2 (CDK2) and acts as a regulatory subunit. CDK2 is required for cell cycle G1/S transition. Overexpression of CCNE1 has been observed in many tumors, such as breast, ovarian, endometrial, and bladder cancer.
The AlphaLISA SureFire Human Total Cyclin E1 Detection Kit is a sandwich immunoassay for the quantitative detection of total Cyclin E1 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.
Assay versatility
Versatility of Total Cyclin E1 assay in various cell lines
Adherent cells were seeded at 20,000 cells/well in a 96-well culture plate in complete medium and incubated overnight at 37°C, 5% CO2. Cells were lysed with 100 µL of Lysis Buffer.
Cyclin E1 levels were evaluated by AlphaLISA SureFire Ultra. For the detection step, 10 µL of cell lysate (approximately 2,000 cells) was transferred into a 384-well white OptiPlate, followed by 5 µL of Acceptor Mix and incubated for 1 hour at RT. Finally, 5 µL of Donor Mix was then added to each well and incubated for 1 hour at RT in the dark. The plate was read on an Envision using standard AlphaLISA settings.
As expected, Cyclin E1 is expressed at high levels in BeWo cells.
