Autoradiography

Autoradiography¬†involves localization, recording of a radiolabel within a solid specimen, and production of image in a photographic emulsion. These photographic emulsions consist of silver halide crystals suspended in a clear phase composed mainly of gelatin. In 1867, first autoradiography was obtained accidentally, when a blackening was produced on emulsions of silver chloride and iodide by … Read More

Freeze Drying

Freeze Drying is also known as Lyophilization or cryo-dessication. It is a process for removing water from the substance by the process of dehydration under vacuum while substance is in frozen state. Lyophilization technology is used to freeze-dry products, such as biologicals, bacterial cultures, analytical chemistry moieties, and therapeutic molecules (e.g., antibodies, vaccines, drugs, and … Read More

Cell Division

Cell division is the process cells go through to divide. There are several types of cell division. Thousands of cells die daily in our body and thousands of new ones are produced. This happens by the process of cell division, in which a parental cell gives rise to two daughter cells. The process involves both … Read More
