Description
Overview
Spleen tyrosine kinase (SYK) is a non-receptor kinase crucial for immune cell signaling, particularly in B cells and microglia. Activated through interaction with phosphorylated ITAM motifs, SYK triggers downstream pathways governing cell activation, proliferation, and survival. SYK acts as both a tumor suppressor and promoter, depending on the cancer type, and is a key driver of autoimmune diseases like rheumatoid arthritis and lupus.
The AlphaLISA
SureFire
Biotin-Free Human Total SYK Detection Kit is a sandwich immunoassay for the quantitative detection of total SYK 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.

Biotin Free assay principle
The Total-AlphaLISA
Surefire
Biotin Free assay measures the expression level of a protein target in a cell lysate.
The Total-AlphaLISA Surefire 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 a proprietary CaptSure 3 agent to capture one of the detection antibodies, which is labeled with CaptSure 3 tag. 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.

Biotin Free 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
Biotin Free 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
Biotin Free one-plate assay protocol
