Counter current immunoelectrophoresis is a modification of immunoelectrophoresis in which antigen and antibody migrate towards opposite directions and form a visible white precipitate in the area between the wells.
Hot air oven introduction A hot air oven is a laboratory appliance
What is pH? pH indicates the concentration of Hydrogen ions in a
Immunoelectrophoresis is a powerful qualitative technique for the characterization of an antibody.
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.
Polymerase chain reaction or PCR is a laboratory technique that is used to make multiple copies (millions or billions!) of a specific region of DNA in vitro (in a test tube rather than an organism).
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.
In molecular biology Western blotting is a rapid and sensitive assay for detection and characterization of proteins. This technique exploits the inherent specificity of antigen-antibody interaction to identify specific antigens by polyclonal or monoclonal antibodies.
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.
The term Giemsa stain originated from a name of German chemist and
What is Nitrate Reduction Test? Nitrate reduction test is used to differentiate
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.
Gerhardt's test is a type of laboratory test which is performed for the qualitative detection of ketone bodies in urine.
Cross Match is a laboratory test, performed prior to a blood transfusion to determine whether donor blood is compatible (or incompatible) with recipient blood.
Reverse grouping is defined as using the reagent cells with known ABO antigens and testing the patient’s serum for ABO group antibodies.
The concept of Blood grouping was first discovered by Karl Landsteiner in 1901, who was an Austrian-American immunologist and pathologist. He received Nobel Prize in Physiology or Medicine in 1930 for this discovery.
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.
