Which types of light chain exist in IgG?

What is the purpose of the Ouchterlony technique?

Which factors does the position of the precipitin line depend on?

Where is a precipitin line thickest? Why?

List some potential experimental errors that could result in unexpected patterns on the Ouchterlony slides.

What pattern is produced when there is identity (identical epitopes) between two antigens on an Ouchterlony slide? Why?

What pattern is produced when there is no identity (both antigens are recognised by the antibody but they do not have identical epitopes) between two antigens? Why?

What pattern is produced when there is partial identity (both have one epitope in common, but one has another epitope that the other doesn't have) between two antigens? Why?
