Description
Overview
Wee1, a serine/threonine kinase, plays a key role in regulating the cell cycle. Wee1 activity is increased in response to DNA damage to support cell cycle arrest. By phosphorylating and deactivating CDK1, Wee1 controls the G2/M cell cycle checkpoint. Wee1 phosphorylates CDK2 during the S phase, preventing cells from moving on to the subsequent cell cycle phase until DNA replication or repair is complete. Wee1 is overexpressed in numerous tumors and has been linked to cancer patients' poor disease-free survival. Thus, Wee1 inhibition is a current research topic, especially with the introduction of novel strategies utilizing PROTACs (PROteolysis TArgeting Chimeras).
The AlphaLISA
SureFire
Human and Mouse Total Wee1 Detection Kit is a sandwich immunoassay for the quantitative detection of total Wee1 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
