Product information
Overview
The AlphaLISA SureFire Ultra total Rb assay is a sandwich immunoassay for quantitative detection of total Rb (phosphorylated and non-phosphorylated) in cellular lysates using Alpha Technology.
Formats:
- The HV (high volume) kit contains reagents to run 100 wells in 96-well format, using a 60 μL reaction volume.
- The 500-point kit contains enough reagents to run 500 wells in 384-well format, using a 20 μL reaction volume.
- The 10,000-point kit contains enough reagents to run 10,000 wells in 384-well format, using a 20 μL reaction volume.
- The 50,000-point kit contains enough reagents to run 50,000 wells in 384-well format, using a 20 μL reaction volume.
In the AlphaLISA SureFire Ultra assay, Donor beads are coated with streptavidin to capture one of the antibodies, which is biotinylated. Acceptor beads are coated with a proprietary CaptSure™ agent that immobilizes the other antibody, labeled with a CaptSure™ tag. In the presence of target protein, the two antibodies bring the Donor and Acceptor beads close together, generating signal. The amount of light emission is directly proportional to the amount of protein present in the sample.
AlphaLISA SureFire Ultra kits are compatible with:
- Cell and tissue lysates
- Antibody modulators
- Biotherapeutic antibodies
Alpha SureFire kits can be used for:
- Cellular kinase assays
- Receptor activation studies
- Screening

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 validation
Evaluation of Rb Total in NRG1 treated cells
MCF7 cells were seeded in a 96-well plate (20,000 cells/well) in complete medium, and incubated overnight at 37°C, 5% CO2. The cells were pre-treated with 20 µM Wortmannin in serum free medium for 2 hours, followed by treatment with increasing concentrations of Neuregulin 1 (NRG1) in serum free medium for 24 hours.
After treatment, the cells were lysed with 100 µL of Lysis Buffer for 10 minutes at RT with shaking (350 rpm). Rb Total and Phospho (Ser780) levels were evaluated using respective AlphaLISA SureFire Ultra assays. For the detection step, 10 µL of cell lysate (approximately 2,000 cells) were 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.
NRG1 induced a significant increase in Rb Phospho (Ser780) levels and a modest increase in Rb total.
Evaluation of Rb Total in Palbociclib treated cells
RT4 cells were seeded in a 96-well plate (40,000 cells/well) in complete medium, and incubated overnight at 37°C, 5% CO2. The cells were treated with increasing concentrations of Palbociclib for 24 hours.
After treatment, the cells were lysed with 100 µL of Lysis Buffer for 10 minutes at RT with shaking (350 rpm). Rb Total and Phospho (Ser780) levels were evaluated using respective AlphaLISA SureFire Ultra assays. For the detection step, 10 µL of cell lysate (approximately 4,000 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, Palbociclib triggered a significant decrease in the levels of Rb Phospho (Ser780) and a modest decrease in Rb Total.
