One of the confusing things about Help Desk management and talking to people about an IT Operations Help Desk, is that people donât understand what Level 1, Level 2, and Level 3 Help Desk support is (as well as Level 0 support and Level 4 support, which not everyone talks about). Hereâs my quick primer on what each of these functions do.
Globulins are immune molecules that are produced by the immune system in response to invasion of the body of agents that are perceived by the system as being foreign. Some immune globulins are also known as antibodies. Examples of microorganisms that stimulate globulin production are bacteria , viruses , molds, and parasites .
Immunoglobulins (Ig), also called antibodies (Ab) , are large Y-shape proteins produced by plasma cells that are used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, called an antigen.he specificity of the immunoglobulin molecule (i.e., whether it will bind to a poliovirus, an E. coli cell, or some other antigen) is determined by the amino acid sequence of the variable regions at the amino-terminal ends of the heavy and light chains.
