Production of Monoclonal Antibodies | 5 Steps and Applications
A recent development in cell biology has allowed the fusion of different cells to form a “hybrid’ cell, which expresses the properties of both parental cell lines. The fusing agent can be a defective virus (Sendai virus that characteristically causes cell fusion) or various chemicals (such as polythene glycol. And this gives rise to cells […]

Bacteria vs Virus Sl.No Character Bacteria Virus 1 Live Organism Yes they are Living Intermediate between living and nonliving. Inside host live 2 Cell Single-celled organism A-cellular (no cell) just a particle 3 Size Bigger in size, […]
Read MoreCitrate Utilization Test | Its Principle, Procedure and Applications
A citrate utilization test is one of the IMVic series groups of tests for identification of bacteria. IMViC stands for Indole, Methyl red, VP, and citrate test. A citrate utilization test helps to detect the organism’s ability to produce citrase enzymes. Those organisms which have an ability to use citrate as the sole source of […]

It is called the VP test, it is one of the tests for the identification of bacteria. In 1898, Voges and Proskauer, a German bacteriologist, first observed the production of red color in the cultures grown in specific media after the addition of potassium hydroxide. But later Harden revealed that red color was due to […]
Read MoreTypes of Immune Cells | Their Role in Body Defense
There are different types of immune cells in the body like Lymphocytes Monocytes and macrophages Basophils Neutrophils Eosinophils The cells of the immune system attack the disease-causing agents like microorganisms, parasites and prevent infections. Some of the cells work by neutralization of foreign material. While others eat and destroy the disease-causing microbes. But few of […]

An organism is one which lives an independent life. Single cell organisms are quite interesting in that with a single cell, they perform the entire activities. There are some billions of cells in human body which make up tissues and further organs to function. In a single cell organism, the cell is so designed to […]

10 Examples of Innate Immunity | Their Composition and Action
Innate immunity is a part of immune system which exists from birth of an individual. It is also called as natural immunity as it is a basic method of defense. This is first line of defense against any microbial attacks to the baby. This natural immunity is essential for the survival of the tender infant […]
Read MoreSterilization Validation | Protocol and Process
Sterilization aims to destroy all the viable forms of microbes. This process is done on routine basis in industry for many products. So to check the efficiency and effectiveness of sterilization, some probes are used to verify it. This is called validation of sterilization. This is done for all methods of sterilization. However, there are […]
Read MoreSteam Sterilization | Its Principle and Process Using Autoclave
Steam sterilization is one of the widely used and dependable methods of sterilization. It is fast, inexpensive and applicable to wide range of products. Sterilization is a process of removal of all the viable forms of organisms from a substance. This mostly is meant to eradicate any living microorganisms in drug formulations, food materials, cosmetics […]
Read MoreElisa and Ria| Similarities & Differences between techniques
ELISA and RIA are two different types of immunoassays used in research and diagnosis. Their principle is similar but their methods of detection and analysis are different. ELISA is a methods where in color is produced out of an immune reaction and the color is estimated for qualitative analysis and quantitative analysis. While RIA is […]
