A dry mount slide is the simplest type of slide preparation in microscopy. It is the process in which a dry specimen is placed directly on the clean glass slide without using any liquid medium. It is the air that remains between the specimen and the objective lens, and the refractive index of air is … Read more
Pseudomonas Aeruginosa Principle The MacConkey Agar is a specialized culture medium widely used in microbiology for the isolation, identification, and differentiation of gram-negative bacteria, particularly those belonging to the Enterobacteriaceae family. The principle of MacConkey Agar lies in its combination of selective and differential properties, making it an effective tool in microbiological analyses. The medium’s … Read more
What is Microinjection? Definition of Microinjection Microinjection is a precise technique used to introduce DNA or other genetic materials directly into a cell using a micropipette or fine glass needle. It is widely employed in genetic engineering, genome editing, and various biomedical research areas. Principle of Microinjection Microinjection operates on the fundamental principle of directly … Read more
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.
What is Filtration? 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 to … Read more
The most frequent tasks in the microbiology area is the determination of the weight or mass of desired substances, chemicals. Another important aspect to be considered is the preservation of substances. Thus, the powders, as well as other granular or paste-like substances should Chamber not be placed directly on the platform for weighing of the balance. It is recommended that glazed paper or a small weigh boats is the best choice to weigh. It is recommended to use glazed papers if the material is 15 grams or less needs to be weighed. A the weigh boat pan or small beaker must be utilized if you are weighing a larger amount. Because of the the light weight of glazed papers its weight is subject to a minimal. If the weight is less of 1 gram an electronic balance is recommended. The larger amount (above 1 grams) is not to be considered using electronic balances.
Soil contain different types of microorganisms which are listed below; Principle of Isolation of Microorganisms from Soil During this process, the soil sample is collected from the study site. After that, the soil sample is dissolved in distilled water and then serial dilution is performed. Then the spread-plate/streak plate method is performed on the sample … Read more
Making a Wet Mount Staining a Slide (After Making a Wet Mount) Adjusting Focusing Tension There is a ring on the inside portion of the right-hand focusing knob on all other compound microscope versions (490 and above). This ring can be manually adjusted to increase or decrease tension. Changing the Eyepiece (M Series Microscope) A … Read more
