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 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.
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.
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.
In this article, we will learn about the Membrane filtration methods, definition, applications, advantages, disadvantages. Before heading towards Membrane Filtration, you have to understand what is filtration? Membrane filtration is a method of separating particles or molecules from a liquid or gas stream using a semi-permeable membrane. The membrane acts as a barrier, allowing some … Read more
