The documentation of gels is a process which is carried out in a photodocumentation of gels, this equipment is part of the special equipment of molecular biology laboratories. Among its functions, it allows to observe, take pictures and analyze the bands of the gels after electrophoresis. In other words, it allows to visualize the bands in the gels that are not visible to the naked eye because these devices have a high resolution and focusing lenses that considerably improve the results.

Thanks to technological development, gel documentation systems are now available, specifically designed to fit the needs of each laboratory, offering innovative solutions for protein image capture and analysis.

The great advantage of gel-based documentation is that it reduces the user’s operating time and, as a result, better quality results are obtained than those obtained by conventional methods. These systems offer better sensitivity and speed, and achieve the lowest detection limits for DNA, RNA and proteins.

Many of the software packages that come with these systems have features such as automatic image capture, user preferences, and automatic analysis, making imaging and analysis much easier.

Types of gels to be analyzed

Agarose gel

This gel is a good electrophoretic support, its nature gives it the particularity to be able to separate molecules according to their size. This gel is used to separate nucleic acids according to their size. It is commonly used to separate large molecules.

Polyacrylamide gel

It is considered the best carrier. They are transparent and chemically inert, uniform and insoluble gels. They are insoluble in water and have a high mechanical stability. It is used in protein electrophoresis because it also allows the separation of molecules according to their size. Among the disadvantages of its use is that it is neurotoxic,
