15 Differences between antigen and antibody
Antigen is a immunogenic portion present on the foreign cell or substance. To combat that antigen or foreign cell, our body’s immune system produces antibodies. Differences between antigen and antibody Sl.No Properties Antigen Antibody 1 Name Anti – AgainstGen – Generate/ formation Anti – AgainstBody-Against the body 2 Other names Also called as Immunogens. Also […]
Read MoreProduction of Monoclonal Antibodies | 5 Steps and Applications
Monoclonal antibodies are set of antibodies which are target specific against a single source of antigen. 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 […]

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 […]

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 […]

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 […]
