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 .
This dye has been used as a counterstain in saturated aqueous potassium alum and in a counterstain solution of 0.1% (w/v) with 5% aluminum sulfate for a Prussian Blue Stain for ferric iron. It has been used as a reagent for calcium in tissue where it forms a scarlet lake.
A real-time polymerase chain reaction (real-time PCR) is a conventional polymerase chain reaction (PCR) based laboratory technique used in molecular biology for real-time monitoring of the amplification of a targeted DNA molecule during the PCR, not at its end, as the conventional PCR do.
In molecular biology and genetics, blotting is an analysis technique used for the detection of specific biomolecules (proteins, DNA or RNA) in samples of complex composition by transferring them onto a carrier such as a nitrocellulose, polyvinylidene fluoride or nylon membrane.
Northern blotting or Northern hybridization is a widely used technique in molecular biology to determine the molecular weight of mRNA and to measure relative amounts of mRNA present in different samples and for identifying alternatively spliced transcripts and multigene family members.
What is a serial dilution? – serial dilution definition Hey there, you might be thinking, what is serial dilution? As the term indicates, it is a series of succeeding dilutions that performed to create a less dense or less concentrated solution from a high dense or concentrated solution. Serial dilution involves performing a series of
The term Giemsa stain originated from a name of German chemist and bacteriologist Gustav Giemsa. He apply this stain with a combination of reagents to detect the presence of malaria parasites. This stain is used for nucleic acid staining and histopathological diagnosis of malaria and other parasites. Giemsa Stain is a types of Romanowsky stains
Before learning about plant tissue culture, first you have to learn about tissue culture and its importance. So, lets jump to the main article- What is tissue culture? The technique in which the tissues or cells are grown on an artificial medium separate from the parent organism is known as tissue culture. An American pathologist
pH Meter Definition A pH meter is a precise instrument that weighs the hydrogen-ion movement in water-based suspensions, showing its acidity or alkalinity expressed as pH. It is also called a “potentiometric pH meter” because it measures the variation in electrical potential between a pH electrode and a reference electrode. The variation in electrical potential
Hot air oven Definition A hot air oven is a laboratory instrument that uses dry heat to sterilize laboratory equipment and other materials. That equipment cannot be wet or material that will not melt, catch fire, or change form when exposed to high temperatures are sterilized by using the dry heat sterilization method. Hot air
BOD Incubator also known as Biological Oxygen Demand incubator. In microbiology laboratories, it is broadly used for cell culture and fungal growth, BOD test, fermentation, crop and physiology, and various pharmaceutical tests etc. BOD Incubator is additionally recognized as a low-temperature incubator or refrigerated incubator because it produces a temperature limit between 5°C to 60°C
What is Dexamethasone? Figure: Chemical structure of dexamethasone | Image by: Maria Palmira Gremiao | Source: www.researchgate.net In 1957, an American physician Philip Showalter Hench first made this drug. Dexamethasone is corticosteroid medication (Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates). Dexamethasone used for the treatment of
