A Lab question antibody recognition

[Username55]

Given a sample blood, what would you do to distinguish different antibodies (MGEAD)?
Also, I am curious as to how the H and L chains are formed ? I can't find any clues in my textbook, please help.
Thanks

Hint: antibodies can be found in all bodily fluids not only in blood, IgM class is the first one to be made after ImmuneSystem's triggered by antigen's proteins. Not many IgD's are found in the sample fluid and little is known about them although their presence is of essence. Also, H and L link together by S-S bonds, (including too the J-chain). Chain polymorphism as well as heterogeneity has no concerns to antibody specificity.
