Hello,
McPherson published the crystal strcuture of an antibody-antibody interaction and as far as I can understand the explanations, the total size of the complex is approx. 15 nm in length. If you assume that the interaction is nearly planar, one can assume for a single antibody an approx. length of 7.5 nm. But please check the link below with the original article...

What is a monovalent antigen?
A monovalent antigen is a type of antigen that contains only one type of epitope, which is the specific molecular structure that can be recognized by the immune system. This means that the antigen can only trigger a response from one type of antibody.
All immunogen are antigen but all antigen are immunogen?
An Immunogen is foreign particle that triggers the body's immune system where as Antigen is also a foreign particle , due to its low molecular weight it is unable to trigger immune system. Example for antigen is Hapten
Can salt be a antigens?
An antigen has to be a protein or molecule of a certain and complex size. NaCl, table salt, is not large enough of a molecule to be an antigen.
Do antigens cause normal immune response?
No. Hapten is an antigen whic has low molecular weight and does not trigger immune system.
What are factors affecting antigenicity?
mention factors affecting antigenicity 1) molecular weight of antigen. e.g. protein is a good antigen as compare to lipid or nucleic acid. 2) invecivness of antigen, that is due to toxins or chemicals secreted by the antigen 3) degredibility: antigen should be degreted in body so that body immune system can react against them. 4) complexicity of antigen
What is the molecular size of phenol?
please i want to know the volume and area of phenol molecule
How is the immunogenicity determined?
if the antigen is more foreign , then the immunogenicity is high if the immune response is high, then the immunogenicity is also high Immunogenicity of Antigens : •Determined by -Foreignness -Molecular Size -Chemical Composition -Degradability •Influenced by -Host genotype -Dose and route of administration -Presence of adjuvants

What is the separation of materials by molecular properties such as size?
You think probable to the separation with molecular sieves.
What is size of DMSO molecule?
The molecular formula of dimethyl sulfoxide (DMSO) is C2H6OS. The molecular weight of this molecule is approximately 78.13 grams per mole. In terms of size, DMSO has a molecular diameter of about 6.9 angstroms.
What is the molecule that can be recognized by the immune system?
Antigens.
