To facilitate the identification and visualization of potential methylation sites for restriction enzyme digestion.

Main Methods:

Development of a freeware tool, Methyl-Typing, integrating various databases and methylation-related functions.
Implementation of modules for handling diverse input formats, including gene names, accession numbers, sequences, and primer information.
Demonstration of input protocols and output generation for COBRA assay-related data.
Integration of computational and visualization capabilities for COBRA analysis.

Main Results:

Methyl-Typing offers a comprehensive solution for methylation analysis with a focus on COBRA.
The tool supports multiple input types for flexible data integration and retrieval.
It efficiently identifies all possible methylation sites amenable to restriction enzyme digestion.
Provides essential information for COBRA assay design and interpretation.

Conclusions:

Methyl-Typing is a fast and efficient freeware tool that simplifies DNA methylation analysis via COBRA.
The integrated approach enhances the accessibility and ease of performing COBRA assays.
This tool empowers researchers to readily analyze methylation patterns and their implications.
