Immunoglobulins, often referred to as antibodies, are essential components of our immune system, responsible for defending our bodies against a wide range of pathogens and foreign invaders. These remarkable molecules come in various classes, each with a unique structure and function tailored to combat different types of threats. The five major classes of immunoglobulins are IgG, IgM, IgA, IgD, and IgE.
IgG antibodies, a subclass of immunoglobulins, are essential tools in the realm of scientific research, thanks to their remarkable structure and versatility. These antibodies have a well-defined domain organization that allows them to perform various crucial functions. At the core of their structure, IgG antibodies feature two distinct domains: the variable (V) and constant (C) domains.
Secondary antibodies are crucial in a multitude of applications, particularly in immunodetection techniques like Western blotting, immunohistochemistry and immunofluorescence. Their primary function is to amplify the signal generated by the binding of primary antibodies to specific target molecules. This amplification is pivotal for visualizing and quantifying proteins or other biomolecules within a sample. One essential aspect of secondary antibodies’ reliability is their manufacturing process, which often involves affinity purification.
