What functions of UV transilluminators? UV transilluminators allows the display surface through straight gels fluorescence of proteins and nucleic acids. It specifications include safety switch Dimmable lighting. Additionally efficient power allows UV light bulbs quickly while a glass filter background minimizes unwanted light. All these maximize contrast and sensitivity, allowing better visualization of gels. The electronic ballast and art manufacturing technology produce UV light more intense and uniform. Different sizes of filters available, for gel electrophoresis, Fluorescence DNA and proteins. The 2UV models offer wavelengths 302nm and 365nm. 3UV models offer selecting three wavelengths. All models have fast ignition, better visualization and documentation of gels, lower power consumption and durability of the lamp. Include UV coated plastic that protects against UV radiation. Lightweight and compact, these models use lamp 8 watts.

The series of desktop UV transilluminator provides the researcher uniform and intense sources of ultraviolet light with a compact size. Its special design emits one or two UV wavelengths of excitation intensity for the return of fluorescent lighting transparent materials. Modes of 254nm, 312nm, 365nm, 254 and 365 nm, and 254 and 312nm are available for different applications. There are two options of filter size display size, 26 x 21 cm and 21 x 21 cm to user requirements. Mode is provided to display 365nm gels longwave easily extended periods of avoiding damage photo nicking. 254nnm mode is used to irradiate samples. 312nm mode is suggested to operate generally gel. The wavelength modes have a high intensity or low intensity equipped switch. All transilluminator desktop models are compact, lightweight and economical. You should buy UV transilluminators product for you lab from www.bioolympics.com. Here you can obtain proper biological devices in a reasonable rate.

What functions of UV transilluminators? Transilluminators UV high performance with four 25 W tubes that provide a high intensity of 100 W and ensure uniform fluorescence UV radiation and high sensitivity for observing stained gels. Adjust intensity developed for fluorescence and photographic applications. Photonicking or Photobleaching gel samples during preparation, allows more time for preparation of gel. The intensity setting "Hi" is developed for documentation. Models with two UV wavelengths are the same size and the same design as other performance models, but have a fixed intensity and generate half-wave UV light (302 nm) and long wave (365 nm). The steel frame allows easy cleaning and reduces sample contamination. Backlight enhanced fluorescence applications through a "Background Screen Uniformity" that provides a uniform background and long-life filter. Fans for cooling the surface of the filter, the samples prevent damage and ensure a constant intensity UV.

The removable cover UV protection can be adjusted in height to adjust the viewing angle to the appropriate value. It gloves are used throughout the practice to avoid contact with toxic chemicals and degradation of samples. Each micropipette tip is used only once, to prevent contamination of the samples. Ethidium bromide is a highly toxic compound that under no circumstances is to be played and or inhaled. The UV light can damage your eyes. Before connecting the UV lamp must put a protective screen. In case of doubt, before acting, ask the teachers. The term electrophoresis was used to describe the migration of a charged particle under the influence of an electric field. Many bimolecular (amino acids, peptides, proteins, nucleotides, it have ignitable groups electric charge present in solution and that are separating function of said load when a voltage is applied across the electrodes.

Horizontal electrophoresis gel electrophoresis is a widely used technique for separating nucleic acids. Gels were placed in an electrophoresis chamber immersed in a buffer of pH ~ 8, so that the DNA molecules or RNA electrophoreses will move to the positive pole and that at pH above 5 are negatively charged. Gels behave as a molecular sieve and loaded allow separation based on size and shape molecules. Electrophoresis mobility of a DNA fragment is inversely proportional to the logarithm of its molecular weight. The most widely used polymers are polyacrylamide and agarose. Polyacrylamide gels are used to separate fragments up to one thousand base pairs, and more porous gels, agarose, to resolve mixtures of larger fragments. Agarose is a linear polymer, from red algae, in alternating D-galactose and 3,6-anhydro-L-galactose.

It is also possible to display the separated nucleic acids on the gel if it they are added during preparation a fluorescent compound capable of intercalating between the base pairs of nucleic acids, making it possible to display when the gel is illuminated with ultraviolet light, for example, ethidium bromide, SYBR Green, etc. It is important the use of markers of known size, similar in nature to the DNA problems because they allow calculating the molecular weights of the same, since the distance of migration of a DNA fragment is inversely proportional to the logarithm of its size.
