He ōrite te rohe pūmau i roto i ngā ārai mate katoa o te momo ōrite, engari he rerekē i roto i ngā ārai mate o ngā momo ōrite rerekē. Ko nga mekameka taumaha γ, α me δ he rohe pumau e toru nga rohe Ig (i roto i te raina), me te rohe hinge mo te taatai taapiri; he mekameka taumaha μ me te ε he rohe pumau e wha nga rohe immunoglobulin. He rerekē te rohe rerekē o te mekameka taumaha i roto i ngā antibodies e whakaputaina ana e ngā pūtau B rerekē, engari he ōrite mō ngā antibodies katoa e whakaputaina ana e tētahi pūtau B kotahi, he pūtau B tāruatia rānei. Ko te rohe rereke o ia mekameka taumaha e 110 nga waikawa amino te roa, ka hangaia mai i te rohe Ig kotahi.  Pātai: E hia ngā waikawa amino kei roto i te mekameka taumaha?
Ko te 110
