Description
Overview
Moesin, a member of the ERM protein family, links the actin cytoskeleton to the plasma membrane, playing an essential role in maintaining cell structure and signaling. Activated by phosphorylation at Thr558, Moesin facilitates interactions with actin filaments and membrane proteins. Upregulation of Moesin is associated with cancers like breast and colorectal cancer, promoting tumor growth and metastasis. Moesin also modulates immune cell functions, contributing to autoimmune conditions.
The AlphaLISA
SureFire Ultra
Human and Mouse Phospho-Moesin (Thr558) Detection Kit is a sandwich immunoassay for the quantitative detection of phospho-Moesin 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.

How it works
Phospho-AlphaLISA
SureFire Ultra
assay principle
The Phospho-AlphaLISA
SureFire Ultra
assay measures a protein target when phosphorylated at a specific residue.
The assay uses two antibodies which recognize the phospho epitope and a distal epitope 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 phosphorylated 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 phosphoprotein present in the sample.
Phospho-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 Phospho-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.
Phospho-AlphaLISA

one-plate assay protocol
Detection of Phosphorylated 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
