Analytik Jena has a long tradition in developing high-performance precision analytical systems which dates back to the inventions made by Ernst Abbe and Carl Zeiss. We have grown to become one of the most innovative manufacturers of analytical measuring technology worldwide.

If zoom lenses are so flexible, why haven’t they replaced the others? The main reason here is image quality — common zooms, especially those having a ratio larger than 3x, cannot produce photos as sharp as primes do. Also, they usually cannot capture as much light as the fixes. Moreover, even though these lenses can zoom in a lot, you might still want to use a dedicated macro lens to make exceptional close-up photography.

Upon determining its novel utility for fluorescence labeling in other living organisms, the development of new molecules has expanded the range of available fluorescent proteins to encompass almost the complete visible spectrum from 350 nm (UV) to 750 nm (Infrared).

That is why zooms are very common lenses and are great in many cases — street and press photography, wildlife, and so on.

These requirements for acquiring images and preparing samples largely limits opportunities for entry-level researchers or students to participate in research involving in vivo applications.

Usually, depending on the spectrum of the fluorescent protein as shown in Figure 2b and c, the fluorescent signal will be pseudo-colored. Compositing the colored fluorescent images with a white light image helps to locate the fluorescent signals on the animal.

The mouse model which was utilized for this experiment is created from colored silicone rubber. In order to mimic the look of the true nude mouse model commonly used in fluorescent in vivo imaging white and red and acrylic paints were applied.

Depending on your shooting environment and goals, both of them can be a great selection. If flexibility is what you need, then go with a zoom. Landscapes or architecture will still look great in your family photo slideshows. If you are taking pictures in a more specific environment, like sports events or wildlife, a telephoto lens could really bring your photos to the next level.

School laboratories can utilize these instruments for teaching purposes and can use this article to supplement STEM training, particularly students aiming for advanced degrees and research careers.

Additionally, they can be divided into short telephoto (85mm - 135mm), medium telephoto (longer than 135mm), and super telephoto (longer than 300mm+). The further your subject is, the longer focal length you need.

The variable focal range can be helpful for a quick reframing of a scene without changing lenses or physically moving closer or further away. You just need to rotate the zoom ring to get a new composition in the viewfinder. Therefore, you don’t need to buy and carry many lenses with you, saving both your money and space.

In order to practice in vivo imaging methods and get a taste of how in vivo imaging works in a laboratory setting, researchers are quickly able to work with the UVP GelSolo and a silicone mouse sample.

The emission filter for GFP has been selected as 510 nm to 523 nm with a peak wavelength of 513 nm. The emission filter designed for RFP has a wavelength range of 575 nm to 640 nm and a peak wavelength of 605 nm.

In addition to complicated sample preparation procedures, imaging the fluorescent proteins within small animals requires specialized instrumentation consisting of an excitation light source, a high-performance camera, emission filters, and associated software.

Also, you can meet the so-called ratio, to describe zoom lenses, for example, 3:1 or 3x. It is calculated by dividing the longest focal length by the shortest and meaning how much you will be able to zoom in (zoom out).

An easy-to-use entry-level imager, the UVP GelSolo, is an ideal option for multi-user laboratories, school laboratories, and practical training where users may not have access to relevant samples or experience with in vivo imaging.

The enhanced properties and unique characteristics of fluorescent proteins have since permitted the non-invasive visualization of dynamic processes and structural organization in living cells and organisms by in vivo imaging2. This technology enables subjects to be monitored longitudinally over the course of a study to supply real-time information on internal changes.

The UVP GelSolo imager was used to image the silicone mouse. Selections for exposure time, light sources, and emission filter are shown in Table 1.

A zoom lens is the opposite of a prime lens. While the latter has a fixed focal length, the former has a variable one. Usually, it is represented in millimeters and you can find the shortest and the longest focal lengths range on the barrel. For example, 18-55mm, or 70-200mm.

A lens is an important element of any camera. A kit lens that usually goes with a DSLR camera can be a good starter, but at some point, we start looking for something else to take our photos to the next level.

The fast and simple tracking of primary and metastatic cancer development research in live animals is enabled within vivo imaging using fluorescent proteins. Discovered decades ago in the jellyfish Aequorea victoria as a primary feature of bioluminescence1, a green fluorescent protein (GFP) is a commonly utilized fluorescent dye for in vivo imaging.

The results exhibit the distinct imaging of fluorescent signals within an organism in an easily reproducible and non-invasive manner. In addition to the in vivo image acquisition method, researchers and students will also be able to learn post-processing for captured in vivo images.

Two pieces of 1 cm red round plastic fluorescent rods were inserted into the head of the silicone mouse and two pieces of 1 cm green-yellow round plastic fluorescent rods were inserted into the back of the mouse before the silicone model was completely solidified to visually mimic tumors. The silicone rubber mouse then set for four hours and was subsequently imaged.

Students at non-research institutions who are interested in learning in vivo imaging but might not have access to animal models can use the UVP GelSolo to practice the in vivo imaging method.

The UVP GelSolo was employed to image a fluorescent silicone mouse embedded with both red and green round plastic fluorescent rods. The fluorescent rods were selected because red fluorescent protein (RFP) and green fluorescent protein (GFP) are frequently used for in vivo imaging.

The intensity of the signal can be analyzed using the Area Density feature in the software for a more in-depth analysis. As an easy-to-use system, the UVP GelSolo is designed for imaging and analysis without the requirement for any additional training.

The silicone mouse and the individual GFP and RFP signals are clearly detected with the UVP GelSolo imaging system, as demonstrated in Figure 2a-c. Figure 2d shows the location of each signal in a composite image.
