Important Knowledge On Gel Imaging Systems

By Nancy Lee


Gels have become cornerstones in carrying out investigations in various fields. Nevertheless, they usually involve complex and imaging processes that rely on trial and error in order to get best images. Gel imagers are widely used in laboratories in molecular biology for documentation of nucleic acid together with the protein suspended agarose gels. Gel imaging systems are used for recording and measuring stained agarose gels using a high technology digital platform.

By digitizing gels, it not only offers benefits of effective data storage and convenience but also gives an accurate way of quantifying the sample. Various instruments are normally used to quantitatively read the nucleic acid, dot blots, protein bands and microplates. Such instruments may include, ethidum bromide, fluorescence, chemiluminescence and visible light detectors. Mostly, these gel systems are usually compatible with Mac or PC operating systems and are normally acquired complete with software.

Through gel imaging, you can manipulate the images for presentation reasons. It is also possible to store the images at your own convenience. Again depending on the compactness, detection mode system flexibility, resolution and cost, it is possible to keep the right fit for your research going through the different models in your bio-compare collection.

Gels documentation system evolved from the old days of dark rooms and blue stains. Today, technologies are available that make it easier to simplify visualization and documentation of your results in gel experiments. Gels are used to characterize DNA, protein as well as small molecules. When used for DNA, they are used for separation, sequencing, and preparation. Documentation and imaging are also essential in such applications.

Modern systems and documentation processes are able to provide highly accurate quantitative results. Some of the available products today include one system that has the instrument and the software. Nevertheless, when choosing gel documentation systems, you will need to consider the requirements for the research. For instance, in a simple application, a more basic system would be ideal and economical while a system with advanced features would be ideal for a sophisticated application.

A digitized gel documentation and imaging system is normally designed to give high-quality images as well as analyzed results in a click of a button. A digitized system makes the analysis very easy due to certain features such as auto image capture, user preferences, and auto analysis among other important features. These features have made the imaging system an essential tool for researchers.

Several benefits have been attributed to this imaging system. First, it is easy to use. Even researchers who are not more familiar with this system can easily learn to use it faster. Secondly, you are able to get quality images together with a complete data analysis. Some of the analyzed results may include bands quantification, molecular weights, PDFs and Excel reports among other results within a few minutes.

Another benefit of this system is that you can be able to save time as well as space. First, you get the results without time wastage. Again you save valuable bench space when you employ this compact system
