Humoral immunity and Cellular immunity are two kinds of adaptive immunity during which a particular immunologic response is produced for a specific pathogen. In humoral immunity, antibodies are produced by the plasma T-cells. While in the case of cell-mediated immunity, T cells induce the apoptosis of the infected cells. Humoral immunity destroys the extracellular pathogens while cell-mediated immunity destroys the intracellular pathogens.

Antibodies or immunoglobulins are a class of disease-fighting proteins produced by B cells found in the lymphatic system or bone marrow. Antibodies are produced to bind a specific antigen that has stimulated the immune system. Their selectivity and tunability to recognize and bind an almost infinite range of large- and small molecule substrates is what makes antibodies so important to the immune system.
Fermentation Technology Notes PPT PDF Fermentation Technology: i. Anaerobic process that generates energy by the breakdown of organic compounds.ii. Any process that generates bacterial metabolites as end products: lactic acid,…
Blotting is the technique in which nucleic acids or proteins are immobilized onto a solid support generally nylon or nitrocellulose membranes. Blotting of nucleic acid is the central technique for hybridization studies. Nucleic acid labeling and hybridization on membranes have formed the basis for a range of experimental techniques involving understanding of gene expression, organization, etc.
Enzymes are macromolecular biological catalysts. Enzymes accelerate or catalyze chemical reactions. The molecules at the beginning of the process are called substrates and enzymes convert these into different molecules which are called products.
