A microscope comes with an objective of 10X (low power) 45X (high power) and 100X (oil immersion). and the ocular lens with 5X, 10X and 15X. In general, an 10-X ocular lens is used in most cases. If an animal can be clearly seen with 10X ocular lens and 45X objective, this means that the size is 10x45, which is 450 times larger than the standard one. We don't know the exact measurement is ? It could be determined using an calibrated scale. Thus the calibration of all lenses (eyepieces) is performed.
A well-established microbiology laboratory is necessary for the work of microorganisms. The students/researchers/scientists must follow the basic rules while working with microorganisms.
Staining protein gels using Coomassie Brilliant Blue R-250 is common to see proteins that are resolved using SDS-PAGE. It is extremely sensitive and suitable for long-term storage of gels.
Modified Kirby-Bauer disc diffusion test is a standard method that can be used as a regular method to assess the susceptibility test to a bacterial isolate in the clinical laboratory.
Proteins are polymers of amino acids. They are complex organic compounds containing nitrogen, hydrogen, carbon and oxygen. Proteins are abundant in our everyday food e.g. egg, soya bean, pulses, fish, milk etc. The presence of proteins can be confirmed qualitatively by usign several tests, Xanthoproteic test is one of them. Due to the presence of characteristic side chains in them, certain amino acids exhibit typical color reactions that form the basis for their identification.
The catalase test is a type of biochemical test which is used to detect the production of catalase enzymes in the organism.
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.
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.
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.
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.
The restriction enzymes cleave the DNA molecule at a specific site or specific nucleotide sequence, is known as recognition sequences or Restriction sites.
Southern Blotting is a molecular biology technique used for the identification of a specific DNA sequence in a collected DNA sample.
Dot Blot is a simplified technique of western blotting, which is mainly used for the detection of proteins.

Before learning about plant tissue culture, first you have to learn about tissue culture and its importance. So, lets jump
The food supply upon which microorganisms thrive in laboratories is termed as a culture medium or culture media. Culture Medium
Methylene Blue Reduction Test also known as mbrt test. It is a qualitative test for milk, it used to check
