Colocalization Analysis
Colocalization is a powerful analytical technique that reveals details about the composition of a sample With Particle Metrix’s ZetaView® systems, researchers can quantify colocalized markers with high precision, providing critical insights into particle interactions and complex biological systems.
What is Colocalization?
Colocalization refers to the ability to detect and quantify the overlap or proximity of two or more distinct signals, typically fluorescence-based, within a sample. It is used to identify markers that are spatially associated on particles or molecules, such as EVs liposomes, and other nanoparticles.
This technique is particularly valuable for understanding the composition and purity of samples, enabling researchers to study co-expressed markers, binding events, or the structural organization of biological or synthetic systems.mKey Attributes of Colocalization:
Spatial Analysis: Measures the overlap of fluorescence signals to determine the simultaneous presence of multiple biomarkers.
Quantitative Insights: Provides numerical data on the degree of colocalization, enabling accurate comparisons.
Multi-Channel Capabilities: Simultaneously analyze multiple fluorescent markers within a single sample.
Why is Colocalization important?
Colocalization is critical for understanding interactions and relationships within complex systems. By identifying which markers are co-localized on particles or molecules, researchers can gain insights into biological pathways, material performance, and environmental interactions. For instance:
In biotechnology, colocalization helps analyze the binding of Extracellular Vesicles (EVs) to target cells and identifies co-expressed markers on bio-nanoparticles like EVs.
In pharmaceuticals, it is used to track drug delivery particles and their association with target sites.
In materials science, colocalization enables the study of composite materials or functional nanoparticle assemblies.
How is Colocalization measured?
Colocalization is measured using advanced systems like the ZetaView® analyzer, which combines fluorescence detection with high-resolution imaging and multi-parameter analysis. The process involves:
- Fluorescence Detection: Particles or molecules are tagged with different fluorescent markers, each emitting light at a specific wavelength.
- Parallel Imaging: The ZetaView® system uses multiple lasers to detect fluorescence signals from labeled components within a sample.
Overlap Analysis: Advanced algorithms determine the spatial overlap or proximity of the detected signals and extrapolate the probability of colocalization , This approach ensures precise and reproducible quantification of colocalization in complex samples.
