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).
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.
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.
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.
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 10×45, 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.
