Latex agglutination test is a simple serological test where antigen and antibody reaction is made visible on the surface of latex particles. It is the process in which latex beads are coated either with antigen or with antibody and when a sample containing the corresponding component is added, the beads is clumped together forming visible … Read more
Agglutination Test is a serological test in which the antigen and antibody reaction is seen directly as visible clumping. It is the process where particulate antigen reacts with its homologous antibody and form aggregates called agglutinates. These aggregates can be seen with naked eyes. This reaction is specific because the antigen combines only with the … Read more
A spectrophotometer cuvette is a small optical cell that is used to hold the liquid sample during absorbance or transmittance measurement. It is usually made in a rectangular shape and two opposite sides are kept clear and highly polished so that the light beam can pass through the solution without scattering. It is the process … Read more
Microbiology is the study of microscopic organisms like bacteria, viruses, fungi and some parasites, and it is the field that explains how these organisms is involved in different biological and environmental activities. A career in microbiology is followed when a person study these microbes and work with them in laboratories or research centers. It is … Read more

It is the reptile that is found naturally in New Zealand, and it is considered a very old lineage that diverged from other reptiles in ancient geological time. The body … Read more
A pH meter is an instrument that is used to measure the pH of a solution, and it is the value that shows how acidic or alkaline the solution is. It is the process where a glass electrode and a reference electrode are placed in the sample, and the potential difference formed between them is … Read more
Brucella is a genus of small Gram-negative coccobacilli. It is non-motile and non-spore forming, and it is the organism responsible for a zoonotic disease called brucellosis. It is the process where the bacteria survive as facultative intracellular parasite inside different host cells. These organisms are named after David Bruce and are placed under the family … Read more
Gradient PCR is referred to as a PCR optimization method where a range of annealing temperatures is tested at the same time in a single run. It is done in a thermal cycler that contain a gradient block, and this block is made in such way that one side hold lower temperature while the opposite … Read more
What is Bright Field Microscope? Bright field microscope is an optical microscope that produce a dark image of the specimen against a bright background, and it is the most common compound light microscope used in biological laboratories. It is the system where the specimen is illuminated from below by a uniform beam of light, and … Read more
What is Ocular Micrometer? The ocular micrometer, which many student’s usually call as the eyepiece micrometer, is basically a small circular glass disk that stay fitted inside the microscope eyepiece, and it carry a tiny ruled scale engraved on it. In general terms, this scale look like a simple series of line’s, but it is … Read more
