Area of Science:
- Bioinformatics
- Computational Biology
- Genetics
Background:
- Gel electrophoresis is a fundamental technique in molecular biology for separating DNA or proteins.
- Analyzing electrophoresis images to generate phylogenetic trees can be complex and time-consuming.
- Existing software often lacks user-friendliness and advanced image correction capabilities.
Purpose of the Study:
- To introduce GelClust, a novel software for processing gel electrophoresis images.
- To provide a user-friendly and accurate tool for generating phylogenetic trees from gel images.
- To highlight GelClust's unique ability to automatically detect and correct gel smile effects.
Main Methods:
- GelClust software was developed using C# for the Windows operating system.
- The software guides users through a seven-step process from image input to dendrogram output.
- Experimental validation was performed to compare GelClust's accuracy and performance against existing software.
Main Results:
- GelClust demonstrated high user-friendliness, simplifying the image-to-dendrogram workflow.
- The software achieved superior accuracy in image processing compared to other available tools.
- GelClust successfully and automatically corrected gel 'smile' effects, a common artifact.
Conclusions:

01:22Two-dimensional Gel Electrophoresis
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method involves protein separation by two dimensions, mass and charge, making it more accurate than one-dimensional gel electrophoresis.
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
