Resolving Power
The presence of a protein can be indicated through various methods, such as enzyme-linked immunosorbent assay (ELISA), Western blotting, or immunohistochemistry, which utilize antibodies specific to the target protein. Additionally, techniques like mass spectrometry and protein assays (e.g., Bradford or BCA assays) can quantify protein levels. Visual techniques, such as gel electrophoresis, can also reveal protein presence based on size and migration patterns. Each method provides distinct insights into the protein's abundance and functionality.

An electron microscope is best suited for studying objects at the nanometer scale, such as viruses, bacteria, cell structures, and nanomaterials. It provides high-resolution images and can reveal details that are not visible with a light microscope.
The standard HIV test, whether a rapid test or one sent to the laboratory, will detect the presence of antibodies to the HIV virus. When the body becomes infected, it will attempt to fight the infection by developing antibodies. Therefore, if a test finds antibodies, it has in essence indicated that the HIV virus is also present.
Under a transmission electron microscope, one can see the internal structure of cells, tissues, and individual molecules at a very high magnification. This type of microscope can reveal details such as the arrangement of atoms and the ultrastructure of organelles within cells.
Diagnosis is based first on the laboratory examination of the urine and the blood. While the urine will reveal significant quantities of protein, the blood will reveal abnormally low amounts of circulating proteins. Blood tests will also reveal.

When the body becomes infected, it will attempt to fight the infection by developing antibodies. Therefore, if a test finds antibodies, it has in essence indicated that the HIV virus is also present.
A polarizing light microscope is best suited to observe birefringent minerals and fibers. This type of microscope is specifically designed to analyze samples that exhibit optical properties like birefringence when light passes through them. The polarizing filters in this microscope help to reveal different colors and textures in the sample, making it ideal for studying birefringent materials.
You would typically use an electron microscope to study the internal parts of a cell, as it provides much higher magnification and resolution compared to a light microscope. Electron microscopes can reveal detailed structures inside cells, such as organelles like mitochondria and the nucleus.
An electron microscope is useful when studying bacteria because it offers higher magnification and resolution compared to a light microscope. This allows for detailed examination of the ultrastructure of bacteria, including their cell wall, membrane, and internal organelles, which can reveal important information about their morphology and function.
It magnifies the specimen by a certain degree to make it appear larger and let you see more detail which were not visible to the naked eye. It is done with the help of lenses which are aided in microscope
