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.

what is the difference between pf soluble and insoluble
The only difference between the two is with active agglutination you have a particulate Ag + Ab, since the Ag is particulate, large, when a complex is formed it is visable. In passive agglutination the Ag is soluble so it must first be attached to something like latex beeds or a carrier so when agglutination occurs it can be seen with the naked eye.
it cannot be solved because it is soluble
Turbidity measures the degree of light is scattered by suspended particulate material and soluble colored compounds in the water. Absorbance measures the amount of light absorbed by the constituents in the water with a specified wavelength.
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.

1 will dissolve to make a solution, 1 won't.
K1 is fat soluble and K2 is water soluble.
precipitation
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
