Representative two-dimensional (2-DE) gel electrophoresis gels of affinity-purified anti-LaA immunoglobulin (Ig)G from patient SS107. (a) Under reduced conditions, the heavy chain species running at ∼55 kDa (gel plug 1) identifies as IGHV3-43 and IGHV3-30, and the light chain species running at ∼25 kDa as IGKV3-15 (gel plugs 2, 3) and IGKV3-20 (gel plugs 4, 5). (b) Under non-reduced conditions the biclonal intact IgG species running at ∼150 kDa comprises IGHV3-30/IGKV3-15 (gel plug 1) and IGHV3-43/IGHV3-20 (gel plug 2) heavy and light chain pairings.
