An antigen can be anything from virus to bacteria to a soluble protein from outside or inside a cell. This includes both foreign and self peptides. An antibody that finds an appropriate antigen will bind to it and your B and T cells determine if it's self or not.
A processed antigen came from cytosol. A protein will be taken by ubiquitin to a proteosome where it is broken up into small peptides. These peptides will make their way into the endoplasmic reticulum (through TAP) where they are exposed to MHC's.

MHC (major histocompatability complex) is the term for the molecules in all vertebrates. HLA (human leukocyte antigen) is the specific term for that class of molecules in humans.
A antigen
Any foreign particle interact with Antibody or T cell is antigen. Interaction is non-covalent and highly specific. Antigen that evoke immune response is called Immunogen. An immunogen usually has a fairly high molecular weight (usually greater than 10,000), thus, a variety of macromolecules such as proteins,lipoproteins, polysaccharides, some nucleic acids, and certain of the teichoic acids, can act as immunogens.
The Phase Variation is the reversible ability of some bacteria to turn an and off the expression of genes coding for the surface antigens . While the Antigenic Variation is the modification of the gene for an expressed surface antigen by genetic recombination with one of many variable unexpressed DNA sequences. In this manner , the expressed surface antigen can assume many different antigenic structures
A soluble antigen is a viral antigen that remains after the virus has been removed. A particulate antigen is produced by particles such as dust and germs.
Antigen binding site or epitope is a part of an antigen that is recognized by the antibody. Paratope is a part of an antibody that binds on epitope.
an aepitope is the part of an antigen where antibodiy or lymphocyte receptor binds

difference between an antibody and an antigen
What's the difference between food preservatives and processed food.
An antigen is a body's system for creating antibodies to fight infection. A pathogen is an infectious agent (or germ).
inoculation is the injecting of a harmless form of antigen into a person or animal contamination is the polluting or infecting of a substance or object
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
Data is raw, unorganized facts that need to be processed. When data is processed, organized, structured or presented in a useful, it is called Information.
The only difference is the origin of the solution. A naturally-occurring solution is one that comes about by natural processes with non human interference. A manufactured or processed solution is one that is created by industrial production, in a laboratory, or from other human processes.
The main difference between batch sharing and time sharing is that in batch sharing system tasks are processed in order in which they arrive. Whereas, in the later the system switches between tasks.
