Question

least three characteristics unique to antigens, three characteristics unique to antibodies, and three characteristics that both antigens and antibodies share.

Answer 1

3characteristics unique to antigen-1.antigenecity_property that allows a substance to combine with antibodies or TCRs.

2.immunogenecity_ability to induce humoral /cell mediated immunity.

3.antigens are multivalent_valencies(binding sites) can be upto 100.

3characteristics unique to antibodies_

1.these are immunoglobulins(glycoproteins) having properties like specificity and sensitivity.

2.each molecule has 3parts when split by papaine_(one crystalisable-Fc and 2antigen binding-Fab).

3.class switching_on antigen stimulation,the H chain VDJ unit can join any constant heavy gene segment and express paerticular antibody class.

3charactristic in both antigen and antibody_

1.both react in a spifically observable manner(antigen rects with homologous antibody and viceversa,however cross reaction may occour due to antigenic similarity).

2.They both have affinity toward each other(epitope_paratope).

3.Both antigen and antibody participate in formation agglutinates or precipitates.
