Cellulose Acetate Electrophoresis (CAE) is a method of separating charged molecules, including proteins, based on their charge and size. It uses a cellulose acetate sheet as a medium for separation, and an electrical current to move the molecules through the medium. The charged molecules are separated based on their migration rate through the cellulose acetate … Read more
A microtome is a scientific instrument used to cut very thin slices of material, typically for use in microscopy. The material being sliced can be a variety of things, including biological tissue, plant specimens, or materials for industrial or electronic purposes. The microtome works by holding the material in place and then moving a blade … Read more
A compound microscope is a class of optical or light microscope. I have already discussed about basics of a microscope on my previous note “Parts of Microscope with their Functions and Working Principle”, you can check them to get an idea about from which class compound microscope belongs and what is a microscope, and more. … Read more
What is Pulsed-field Gel Electrophoresis (PFGE)? Principle of Pulsed Field Gel Electrophoresis (PFGE) The principle of pulsed-field gel electrophoresis (PFGE) revolves around the separation of DNA fragments based on their size using an electric field. In conventional gel electrophoresis, small DNA fragments migrate more easily through the gel matrix than large fragments. However, when dealing … Read more
Fluorescence spectroscopy is an analytical technique used to examine the characteristics and interactions of molecules. It is founded on the idea that when a molecule absorbs a photon of light and becomes excited, it emits light at a longer wavelength, a phenomenon known as fluorescence. This emitted light can be collected and studied in order … Read more
Phylum Nemathelminthes General Characteristics of Nemathelminthes Phylum Nemathelminthes, also known as Nematoda or roundworms, exhibit several general characteristics that define their biology and classification. Here are some key characteristics of nematodes: Structure of Nemathelminthes Nemathelminthes, also known as roundworms or nematodes, exhibit a unique structure that distinguishes them within the animal kingdom. Here are the … Read more

What is Phytoplankton? Definition of Phytoplankton Phytoplankton are microscopic, photosynthetic organisms found in aquatic environments that serve as the foundation of marine and freshwater food chains and contribute significantly to global oxygen production and carbon cycling. Characteristics Features of Phytoplankton Phytoplankton are a diverse group of microscopic photosynthetic organisms that inhabit aquatic ecosystems, and they … Read more
What is Dinoflagellate? Definition of Dinoflagellate Dinoflagellates are single-celled eukaryotic microorganisms, primarily found in marine environments, characterized by two whip-like flagella that facilitate movement. Many species are photosynthetic, and they play vital roles in aquatic ecosystems, ranging from primary producers to causing phenomena like bioluminescence and red tides. Dinoflagellates Classification Dinoflagellates are a diverse group … Read more
Cnidaria comes from the Greek word cnidos, which means stinging thread. The existence of cnidae characterises these creatures. Cnidaria is a phylum within the Kingdom Animalia that contains 10,000 known species, including corals, sea anemones, jellyfishes, and hydras. These organisms are found in both marine and freshwater environments. It is an additional ancient group with … Read more
