Flow Cytometry-based MAPK Pathway Assay Service
Introduction
The MAPK (Mitogen-Activated Protein Kinase) signaling pathway is pivotal in regulating various cellular processes, including proliferation, differentiation, and survival. Hyperactivation of the MAPK pathway is implicated in a significant proportion of human cancers, making it a critical target for therapeutic interventions. At Creative Biolabs, we utilize state-of-the-art flow cytometry techniques to evaluate the activation status of the MAPK pathway, providing insightful data that supports both basic and clinical research.
Assessment of MAPK Pathway by Flow Cytometry at Creative Biolabs
Flow cytometry is a powerful tool used to measure the phosphorylation status of signaling proteins within the MAPK pathway, such as ERK1/2. This method allows for the simultaneous assessment of multiple markers at the single-cell level, offering a high-throughput and detailed analysis of cellular signaling.
Our technology at Creative Biolabs enables precise quantification of phosphorylated ERK1/2 versus total ERK1/2, allowing us to determine the activation status of the MAPK pathway efficiently. We employ phospho-specific antibodies that selectively bind to the phosphorylated forms of these proteins, providing an accurate measure of pathway activation or deactivation.
Service Contents
Detailed Phospho-Specific Analysis
-
Our phospho-specific flow cytometry assays measure the phosphorylation levels of key MAPK components under various conditions. By employing antibodies specific to the phosphorylated forms of proteins like ERK1/2, we offer a comprehensive overview of MAPK pathway dynamics.
Multi-parametric Assessment
-
We analyze multiple signaling nodes concurrently, including Akt, JNK, NF-κB p65, p38, STAT3, STAT5, ZAP70, and Rb. This multiplexing capability facilitates a holistic view of the signaling networks and inter-pathway crosstalk, crucial for understanding complex biological contexts such as cancer.
Customized Modulation Condition
-
We provide assays under a variety of modulatory conditions including treatment with H2O2, PMA, CXCL12, and IL7. This flexibility ensures that specific external stimuli's impact on MAPK pathway regulation can be accurately assessed.
Benefits of Our Service
-
High Sensitivity and Specificity
Our phospho-specific antibodies ensure high sensitivity and specificity in detecting phosphorylated proteins, allowing for precise quantification of MAPK pathway activation.
We provide a multiparametric analysis that captures the complex dynamics of the MAPK pathway, including feedback loops and cross-talk with other signaling pathways.
Flow cytometry analysis at Creative Biolabs offers single-cell resolution, enabling the detection of cell-to-cell variability in pathway activation which is particularly valuable in heterogeneous samples such as tumors.

Summary
|
Flow cytometry-based assays are backed by substantial scientific literature demonstrating their effectiveness in assessing intracellular signaling pathways. For example, phosphorylation flow assay was used to detect multiple targets such as ERK1/2 and JNK, revealing high signal variability among T-ALL cell lines. Each cell population has a different phosphorylation profile and specific signal sensitivity to phosphatase inhibition and PKC activation.
