What is pH Meter? Definition of pH Meter Advertisements A pH meter is a scientific instrument used to measure the acidity or alkalinity of aqueous solutions by determining the hydrogen-ion activity, expressed as pH. It operates based on the difference in electrical potential between a pH electrode and a reference electrode. What is pH? In … Read more
Advertisements A hot air oven is a laboratory appliance that is used to dry, sterilize, or heat materials. It works by circulating hot air inside the oven chamber to evenly distribute heat to the materials being processed. Hot air ovens are often used in a variety of settings, including research laboratories, industrial settings, and educational … Read more
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.
What is RNA? Definition of RNA Advertisements RNA, or Ribonucleic acid, is a nucleic acid molecule that plays a crucial role in gene expression and protein synthesis. It is a single-stranded molecule composed of nucleotides, including adenine (A), cytosine (C), guanine (G), and uracil (U). RNA carries genetic information from DNA and acts as a … Read more
A Molecular Biology Technique is used for the identification of Post Translation Modification mostly carbohydrate Epitopes by transferring onto a membrane and analyzed using a probe.
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.
Advertisements 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 … Read more
What is Filtration? Advertisements Filtration is utilised to separate a dispersion based on particle size. The filtered mixture is put to an appropriate porous material filter. Particles smaller than the filter’s pores can pass through and enter the filtrate, while larger particles are retained on the filter’s surface. Filtration is a process that is used … Read more
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.
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 differentiate Staphylococcus aureus from coagulase-negative staphylococci. S.aureus produces two forms of coagulase (i.e., bound coagulase and free coagulase).
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.
A synchronous or synchronized culture is a microbiological culture or a cell culture which contains the cells that are all in the same growth stage.
Pyronin Y(G) (PY) is a dye used for DNA staining. PY has orange spectral emission that is easily distinguishable from FITC and 7-AAD.
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.
This “Mayer’s hemalum solution – for microscopy” is used for human-medical cell diagnosis and serves the histological and clinico-cytological investigation of sample material of human origin.
Immunofluorescence Quenching Solution is used in immunofluorescence and immunocytochemistry applications.
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.
