Rocket Immunoelectrophoresis (RIEP) also known as electro-immuno diffusion is a simple, quick and reproducible method for determining the concentration of antigen (Ag) in an unknown sample.
It is a type of biochemical test, which is used to differentiate Staphylococcus aureus from coagulase-negative staphylococci. S.aureus produces two forms of coagulase (i.e., bound coagulase and free coagulase).
Spread Plate Method in microbiology The spread plate method is used to isolate individual colonies from a diluted sample of mix population. Different methods have been developed for the isolation of microorganisms from a mixture sample but among them Spread plate culture method is the most widely used technique in laboratory. An ideal spread plate … Read more
The pour Plate Method technique was created in the laboratory by Robert Koch and is still widely used in the laboratory since his time. This technique is appropriate for Microaerophilic, facultative, or anaerobic microorganisms. It is straightforward to use, requires fewer resources, and is simple and cost-effective. However, it requires the specimen to be placed … Read more
Streak Plate Method Overview There are two types of microbial culture such as mixed culture and pure culture. The mixed culture contains two or more species while the pure culture contains only a single species. During the identification of a microorganism, the first and important step is to isolate the individual species from a mixed … Read more

The oxidase test is a biochemical reaction that assays for the presence of cytochrome oxidase, an enzyme sometimes called indophenol oxidase. In the presence of an organism that contains the cytochrome oxidase enzyme, the reduced colorless reagent becomes an oxidized colored product .
It is a type of biochemical test which is used to distinguish reducing sugars from non-reducing sugars. This biochemical test is also known as the silver mirror test based on the end product of this test. This test was also used to differentiate between aldehydes and ketones through routine qualitative organic analysis.
In this method, the Group B Streptococcus (CAMP test positive) is streaked in the center of sheep blood agar, and Clostridium perfringens is streaked perpendicular to it.
Gerhardt’s test is a type of laboratory test which is performed for the qualitative detection of ketone bodies in urine.
